An Overview of 4 Types of Indoor Air Pollutants

Mon, 17 May 2021 15:28:41 GMT

Indoor air pollution is a problem that affects us every minute that we're at home, yet most homeowners rarely have indoor air quality on their minds. If you want to improve the air quality in your home, first understand the sources of airborne pollutants in the home. This post will give you insight into four of the most common types of indoor air pollution.

Volatile Organic Compounds

Volatile organic compounds, or VOCs, are a class of pollutants made of molecular compounds that contain carbon, with certain exceptions like carbon monoxide. Common examples of VOCs include formaldehyde, benzene, and methylene chloride. Many VOCs find their way into your home as a byproduct of combustion from tobacco smoke, wood-burning stoves, and other appliances.

VOCs are also present in many materials that are used in the construction of modern homes. Paint, paint thinners, carpet and upholstery, and composite wood products like plywood will all off-gas VOCs continuously at a slow rate. Minimize sources of VOCs and ventilate your home often to reduce your level of VOC exposure.

While exposure to low levels of VOCs may not be harmful to everyone, those with existing respiratory problems are at greater risk. Acute exposure to VOCs can cause symptoms such as sinus irritation, headaches, nausea, and dizziness. Long-term exposure increases the risk of cancer as well as damage to the liver, kidneys, and nervous system.

Biological Pollutants

While VOCs are deemed "organic" because they contain carbon, they usually do not originate from a biological source. Biological pollutants include all contaminants that originate from - or are - living things. Examples include pet dander, mold spores, plant-based allergens such as pollen, and even viruses and bacteria.

Because they come from such a wide variety of sources, it can be difficult to develop a plan for dealing with biological pollutants in your home. In general, you should target areas in your home that are high in moisture, since all living contaminants require a source of moisture to thrive. Clean humidifiers and other moisture-generating appliances often, ventilate your home regularly, and consider installing an electrostatic filter.

Radon

Radon is a colorless, odorless gas that can be found virtually anywhere. Radon is formed as uranium in the earth's crust breaks down, and it makes its way into buildings through any small crack or opening. Radon breaks down into radioactive components and is a leading cause of lung cancer. Radon is dangerous indoors because it can easily build up to unsafe levels.

DIY radon testing kits and radon testing professionals can identify whether radon is a problem in your home. Radon mitigation systems are the most common solution for existing homes with unsafe radon levels. These systems are installed beneath the foundation to vent radon outside before it reaches the interior of your home.

Carbon Monoxide

Carbon monoxide is perhaps the most talked-about indoor air pollutant, and for good reason. Like radon, carbon monoxide is undetectable, but a buildup of CO indoors can quickly become fatal. Carbon monoxide is usually found in the home as a byproduct of combustion in furnaces and other appliances.

To protect homeowners from carbon monoxide poisoning, the gas supplied to the furnace is mixed with a chemical called mercaptan to create a distinctive, sulfur-like odor in the event of a leak. Still, a carbon monoxide detector is always recommended to eliminate any chance of an undetected CO leak.

Improving your home's air quality is a valuable goal to protect your family's health. No matter the source of poor indoor air quality in your home, the professional team at Parks Davis Air Conditioning & Heating can provide the best indoor air solution for your home.

A Guide to New Home AC Maintenance

Fri, 09 Apr 2021 15:35:16 GMT

The purchase of a home comes with a lot of built-in elements homeowners may take for granted. The idea of central air is definitely a perk when purchasing a new home, but there are some caveats along the way. Proper AC unit maintenance will ensure your system runs properly and delivers good air quality.

Learn about some of the essential maintenance tasks needed to run your new home's central air unit and some of the problems that may arise if you ignore the issue.

Dust Build-Up

When you move into a new home, you may not realize how long the home's been empty or unused. For example, if the former owners moved out in early spring and the house didn't sell until the late summer. This means the air conditioner went for months without any use.

During this time, dust, cobwebs, and debris could build up within the unit. All of these factors could have an impact on air quality. Even if the unit was used, you may not know the last time the ducts were actually cleaned out.

Cleaning the ducts is a part of a maintenance package for your central air unit. HVAC technicians can provide professional cleaning services to ensure you have the best air quality. Along with cleaning and inspecting the ducts, the techs will replace air filters to help provide cleaner air and eliminate allergens.

The inspection will also include checks for any blockages. Rodents and small critters could make their way into the ducts and cause blockages that need removal for the unit to work properly.

AC Unit Noises

If you've never owned a home with a central air unit, you may not know what to expect when the unit turns on to supply cool air. Rattles, clangs, buzzing, and other warning signs may seem like typical operations to new homeowners. Before you run the unit for extended amounts of time, you should consider a full test and inspection.

An HVAC technician will run the unit, take note of any noises, and find the source of any problems. In some cases, you may just need minor adjustments. In other cases, you may need to replace parts to ensure the unit operates smoothly. A technician can also educate you on what specific noises mean and when you need to contact them for emergencies.

Part of the tests and inspection will include the performance of the unit. If a unit is under-delivering the proper cool air, a technician will look into performance issues. A unit may overheat or not have the proper output it should.

Cooling Calibration

Through years of use, an air conditioning unit may not properly regulate the temperature in your home. When you move into a new house, one of the main maintenance tasks you should hire technicians for is cooling calibration. The calibration process will ensure the air conditioner outputs the proper temperature that is set on the thermostat.

An extended test process will set a cooling temperature for multiple rooms. HVAC technicians have the tools needed to check the temperature in each room and calibrate the thermostat as needed. Some rooms may have temperatures too hot and others that are too cold.

The calibration will not only help give your air conditioner more accurate results, but you can save money on your energy bill. You will not have to constantly adjust the temperature and force the central air unit on and off in the home. The smoother process will create more consistent results and allow you to remain comfortable in your new home.

Contact us at Parks Davis Air Conditioning & Heating once you have settled into your new home. You can get started off on the right foot and ensure you have cool air for years to come in your new house.

4 Thermostat Problems that Affect HVAC Operation

Wed, 20 Jan 2021 15:47:33 GMT

Your HVAC system will work only as well as the thermostat that tells it what to do and when to do it. Whether you have a vintage mercury-driven thermostat or a state-of-the-art digital model, malfunctions in this key component can prevent you from maintaining a comfortable home temperature range.

Once you have a clearer idea of what can go wrong with thermostats and their accessories, you can recognize HVAC problems that might require thermostat repairs, maintenance, or even replacement. Keep an eye out for these four common home thermostat problems.

1. Power Failures

A thermostat has to have a steady, reliable source of power before it can do its job. Many thermostats get this power from a wired connection that feeds 24 volts from your home's electrical system while also employing backup batteries in case of power loss. Other thermostats rely entirely on battery power.

If your thermostat's batteries have run through most of their capacity, it will probably display a clear warning that the batteries need changing. If you can't get any response from your digital thermostat at all, you may have either dead batteries or a loss of hardwired power (which may require repairs to the wiring itself).

Sometimes the power disconnection occurs within the thermostat itself. For instance, if years of dirt, dust, and other debris have interfered with terminal connections, your thermostat can simply stop working. A loose or corroded wire can also cause a thermostat power failure.

2. Location or Position Problems

Thermostats can prove highly sensitive to their surroundings, including their exact location, position, or orientation in the home. Your thermostat can only respond to the immediate temperature surrounding it. A thermostat placed in an unusually warm or cold area may run your HVAC system based on that isolated temperature.

If your previous installer placed your thermostat too close to a door or window, or if you've modified these features so that they let more sunlight into your home, your thermostat could function inaccurately. Additionally, if your home's foundation has shifted, the change in level could affect an older mercury-bulb thermostat's operation.

Your HVAC technician can often solve this problem by re-leveling the thermostat or relocating it farther away from heat or cold sources. If windows provide too much heat for your thermostat, and you don't wish to relocate the thermostat, try covering the windows with thermal blinds or other insulating materials.

3. Heat Anticipator Issues

Traditional dial-type thermostats have a component called a heat anticipator. This disc-shaped electrical resistor lives up to its name by anticipating the final resting temperature of your home and then shutting off your furnace just before the ambient temperature reaches the desired level.

Even a slight flaw in a heat anticipator's calibration can cause your HVAC system to either shut off before it achieves the right temperature or shoot right past that temperature, making your home too warm. You may experience short cycling, with the HVAC system switching on and off too rapidly to maintain comfortable temperatures.

Fortunately, HVAC technicians can solve this problem relatively easily. Your technician will open the thermostat and manually adjust the calibration settings to make the system follow a longer cycle.

4. Old Age

Any mechanical or electronic device can eventually wear out, including an HVAC thermostat. Eventually, you may notice that your HVAC system never runs, runs constantly, or disobeys your thermostat's commands. An aging thermostat may also start showing differences between its settings and actual room temperature.

The expected lifespan of a thermostat can vary greatly, depending in part on how hard you run your HVAC system. Even the most advanced programmable thermostat may last anywhere from five years to over 20 years . As a general rule of thumb, however, you can expect to get ten years of reliable performance.

If you think you may have a thermostat problem, contact Parks Davis Air Conditioning & Heating. Our team can troubleshoot your entire HVAC system, including the thermostat, and make any necessary fixes to restore comfort to your home.

4 HVAC Tips to Help With a Dusty Home

Tue, 17 Nov 2020 16:04:39 GMT

Do you find yourself dusting your home more frequently than you feel you should have to? You may be surprised to learn that your HVAC system can help - and that it also may be to blame! Here are four HVAC tips that can help you dust less often and keep the surfaces in your home cleaner.

HVAC System for a Dusty Home — Douglasville, GA — Parks Davis Air Conditioning & Heating

1. Maintain Your Furnace Filter

All the air that your HVAC system circulates through your home passes through the furnace filter. In this way, the furnace filter is the first line of defense when it comes to reducing airborne dust. A filter that is clogged with dust and dirt won't be able to trap more dust from the air. Depending on the type of filter you have, you should make a priority to clean or replace it once a month.

In addition to furnace maintaining your furnace filter, you can also see improvements in indoor dust levels when you upgrade to a more efficient filter. Replaceable fiberglass filters have larger spaces between their fibers that some dust can pass through, and they clog easily. An advanced filter, such as an electrostatic filter, will do a much better job of keeping dust out of your home's air.

2. Patch Duct Leaks

Most homeowners are concerned with duct leaks because they allow heated and cooled air to escape and waste energy. However, duct leaks are also problematic because they can draw unconditioned air into your ductwork. This air comes from some of the dustiest areas of your home like crawlspaces and your basement, so duct leaks can significantly increase the concentration of dust in the air.

Patching duct leaks in exposed areas, such as your attic, isn't difficult for DIY-oriented homeowners. The problem is that duct leaks can often develop in ductwork behind walls where homeowners can't reach them. An HVAC technician can give you a complete picture of your ductwork and patch leaks that would otherwise go unnoticed.

3. Get Professional Furnace and Duct Cleaning

Dust doesn't just accumulate on your furnace filter as you use your HVAC system. Over time, dust in the air will build up inside the furnace air handler as well as on the interior of your ducts. Layers of dust in these areas could provide a constant supply of dust from your vents every time you use your furnace or AC, even if your furnace filter is clean.

You can inspect the interior of your furnace for dust by removing the furnace access panel, and you may be able to remove much of the dust with a vacuum hose attachment. Alternatively, you can rely on the services of a professional for more thorough results. An HVAC technician can provide thorough internal cleaning for your furnace as well as professional duct cleaning to ensure your system is as dust-free as possible.

4. Invest in HVAC Add-ons

Homeowners who are looking for optimum indoor air quality will benefit from whole-house HVAC add-ons such as air purifiers and dehumidifiers. These devices are installed in your ductwork, typically in the return duct to process air before it is returned to the air handler. HVAC add-ons provide consistent air quality improvements in every room.

Air purifiers are great at removing dust and other pollutants from the air. One popular option is an ionizing purifier, which electrically charges contaminants in the air so that they stick to metal plates inside the purifier. Dehumidifiers remove moisture in the air that dust and other particles cling to, which makes it harder for them to circulate through your home.

With a little help from your HVAC system, you can enjoy a home that is as close to dust-free as possible. Contact Parks Davis Air Conditioning & Heating today for professional duct cleaning and all your other HVAC needs!

Midnight HVAC Emergency? What to Do Next

Tue, 15 Sep 2020 16:16:42 GMT

HVAC System Stops Working — Douglasville, GA — Parks Davis Air Conditioning & Heating

What should you do if your HVAC system stops working in the middle of the night? Whether during the heat of the summer or the middle of the winter, you need cooling and heating 24 hours a day. If you wake to a hot or cold home (depending on the season), take a look at what you should do next.

Make Sure the Electricity Is On

Did a warm summer night bring on a severe thunderstorm? Windy weather or a lightning strike can turn your electricity, and your air conditioner, off. The same goes for wild winter weather, strong snowstorms, or other similar outdoor issues.

Before you assume something is wrong with your AC or heat system, make sure the electricity is on. This may present challenges in the middle of the night. Even though you could look outside to see if your neighbor's lights are on, chances are they are asleep too. Contact your local power supplier for outage notifications and information.

Wait until the power is restored and turn the system on again. If the air conditioner or heater does not start, call a qualified contractor. The unit might have storm-related damage and requires a reset or a repair.

Check the Electrical Box

A tripped breaker or blown fuse can shut down your home's HVAC system. If your whole home hasn't lost power, but the system stops in the middle of the night, check the electrical box. This easy fix can save you time and restore your home's interior comfort immediately.

Even though a flip of a switch can bring your air conditioner or heater back to life, a more serious issue may be at fault. A short circuit or other electrical issue could cause the breaker to trip (or a fuse to blow) repeatedly. This potential problem requires professional inspection. An HVAC technician can inspect the system, look for possible faults, and repair the system.

Call a Contractor

The power is on, a circuit breaker did not trip, and your heater or air conditioner still refuses to work. It is the middle of the night, and you are not sure what the next step to take is. A possible HVAC problem during regular business hours may only require a quick call to your contractor. But a nighttime issue may throw you for a loop.

If your regular HVAC contractor has emergency services, you are in luck. Call the contractor and explain the problem. Given that you were asleep when the issue started, you may not have much information for the contractor. This means they will need to inspect the system firsthand to diagnose the problem and determine what type of repair the heater or air conditioner needs.

Homeowners who do not have already have a contractor's number stored in their contact list will need to find a professional who provides emergency services. To make this type of situation easier, research a few potential companies right now (before the system stops). Ask friends, family members, or neighbors for the names of reputable service contractors.

Keep Your Home Comfortable

An emergency contractor can provide overnight service. But that does not mean they will arrive immediately after you call.

If your home is extremely hot (in the summer), open the windows, turn on fans, and try to keep cool until the HVAC technician arrives. Keep your wintertime home warm and pull the curtains or window treatments closed, cover yourself (and family members) with quilts or blankets, and wear an extra layer of clothes as you wait for professional heater help.

Airflow Issues? What You Need to Know About Your AC System

Thu, 16 Jul 2020 16:27:00 GMT

Does your central AC system have an airflow issue? Whether your air conditioner blows too high or the air barely flows from the vents, take a look at the questions to ask right now.

Do You Have a New Air Conditioner?

It's possible what seems like a hurricane of cool air breezing into your home is perfectly normal. An older, worn, or damaged AC unit may have restricted airflow. Over time, this can lead you to believe air should trickle or lightly flow from the system.

According to the U.S. Department of Energy, a new high-efficiency system uses between 30 and 50 percent less energy than an older model would. A replacement central air conditioner that works efficiently should seem powerful in comparison to your older, worn system. It should also use considerably less energy.

If you recently installed a new air conditioner and aren't sure whether the high flow is normal, contact your HVAC contractor. While feeling a significant difference with an energy-efficient or higher quality upgrade is normal, you should always leave the final system diagnosis up to the professional. Even though the system is brand-new, it could have a manufacturer's defect or a similar issue.

Does the Filter Have a Clog?

High or hard airflow isn't the only issue to look out for. Poor or low flow can impact indoor air quality and overall home comfort. If your system is slow to cool your home or you can't feel air coming from the vents, check the filter.

A clogged filter restricts airflow into the ducts. This can result in poor home cooling and little to no air circulation. Before you assume the low airflow is a major (or expensive to repair) problem, check the filter. A clogged filter may have obvious debris, dust, or pet fur caught inside. Replace the filter, or if your system has a reusable model, replace it.

Not only can a clog-free air filter increase airflow, it can save you money in cooling costs. A clean or new filter can reduce your AC system's energy use by five to 15 percent, according to the U.S. Department of Energy. Without the clog, the system won't need to work as hard to force air through the ducts and out of the vents. This lightened load decreases energy use and the related costs.

If the filter change did little to help the airflow issue, the ducts might be at fault. Dirty or debrisfilled air ducts can also restrict airflow and limit the cooling capacity.

Are the Coils Dirty?

The condenser is responsible for compressing warmed refrigerant gas and turning it back into a liquid. This exterior part of your AC system is necessary for proper cooling. Dust, dirt, leaves, and other outdoor debris can affect the coils. Dirty coils can reduce the AC system's ability to effectively remove or absorb heat from the air. This can restrict airflow and slow cooling.

Prevention is a key step to stop this airflow problem before it starts. To keep your air conditioner's condenser clean, move potential debris sources away from this exterior unit. Trim shrubs or nearby trees, remove leaves regularly, and don't allow cut grass to blow onto the condenser.

If you suspect a dirty condenser coil is the culprit behind your air conditioner's airflow issues, call an HVAC professional for help. The condenser and its coils are sophisticated cooling machinery. Never attempt to clean a dirty coil yourself. This poses a safety and damage risk. A skilled technician can inspect the area, diagnose the issue, and clean the coil if necessary.

5 Benefits of Duct Cleaning

Thu, 14 May 2020 16:45:49 GMT

Dust and other debris accumulate in your air ducts. While this matter is entering your air, the buildup in the ducts also prevents your HVAC from heating and cooling your home adequately. When you schedule a regular cleaning, you're keeping your family healthy, saving on your energy bills, and even reducing your need to dust, among other benefits.

1. Reduce Pet Dander and Fur and Nicotine

The National Air Duct Cleaning Association (NADCA) recommends regular cleanings for all homeowners. However, your lifestyle and habits may increase your need for routine duct cleanings as well as how often you should schedule them. For instance, the following factors may elevate how often you should schedule cleanings:

Pet dander
Pet fur
Nicotine residue

Pet fur isn't just a nuisance on your furniture. It travels throughout your home and ends up entering into your HVAC system. Over time, it accumulates and hinders your unit's performance. Dander does the same. Therefore, even though you might not have a pet allergy, you'll benefit from having your ducts cleaned if you have pets.

When you smoke in your home, the nicotine adheres to your walls and furniture. It does the same in your HVAC unit. Once you remove the nicotine buildup, your home will smell fresher.

2. Remove Mold and Allergens

An air duct cleaning also removes mold and allergens from your system.

If you suffer from frequent bouts of having a runny nose and itchy eyes or sneeze frequently, you could have a sensitivity to mold. Those with asthma are more prone to sensitivities and may have a more serious reaction to the fungi.

Primarily, mold thrives in moist areas; however, it may grow in your HVAC system. As your unit heats and cools your home, the forced air circulates the mold throughout your home. A duct cleaning service can come into your home and removes the mold. After the cleaning, you and your family may no longer suffer from these allergy symptoms.

Dust accrues in your HVAC ducts as well. While you can't see the mites in the dust, these tiny pests can cause you a great deal of discomfort, ranging from frequent sneezing spells to a recurring runny nose to constantly itchy eyes. Unfortunately, approximately, 20 percent of Americans suffer from a dust allergy. An HVAC tech removes these allergens from your ductwork.

3. Decrease How Frequently You Dust

Do you feel like you're dusting frequently but can't seem to keep up with it? Do you notice dust building up after your HVAC unit runs? Your system may have an overabundance of dust and debris inside.

Besides the benefit of cleaner air, you'll dust less once you have a duct cleaning. The professional removes the dust in your ducts. You won't feel as stressed trying to keep up with your household chores once you schedule a routine duct cleaning.

4. Reduce Your Energy Expenses

Additionally, a routine duct cleaning can positively impact your energy expenses. All the dust, dander, allergens, and other airborne particles don't just harm your family's health; they also hinder air from flowing through your ducts. As they obstruct the air from flowing, your furnace runs more often and for longer to achieve and maintain a comfortable temperature in your home.

5. Improve the Smell of Your Home

Nicotine isn't the only substance in your HVAC system that can contribute to unpleasant smells in your home. The dust and other debris can accumulate and cause a musty odor. A duct cleaning removes these substances in your ducts that cause these smells.

Your and your family's health may benefit from a duct cleaning. In addition, a duct cleaning improves the air quality in your home as well as the smell of your home. You might even notice a reduction in your energy expenses.

Schedule a duct cleaning with Parks Davis Air Conditioning & Heating to improve the quality of the air your family breathes and reduce your energy costs.

Should You Replace Your AC Just Because It's Old?

Fri, 13 Mar 2020 16:56:18 GMT

A typical central air conditioning system lasts no more than about twenty years . This long lifespan means that many homeowners tend to think of replacement as something that's always in the distant future. While it's easy to consider replacement when your system is failing, does it make sense to replace an old, but otherwise functional system?

The adage may be that if it ain't broke, don't fix it, but the decision process for old appliances can sometimes be more complicated. If your home's AC system is fifteen years old or more, then it might be time to consider an upgrade. Here are just four reasons why keeping an old system in operation may be costing you more money than you expect.

1. Warranties Matter

Have you thought much about your air conditioner's warranty lately? If your system is more than ten years old, then it's likely that you haven't. Central AC parts can be expensive, and the typical warranty lasts no more than ten years. Even industry-best warranties only extend a few years beyond this point.

Once your system is outside of its warranty period, you'll be on the hook for the full cost of any repairs. While it doesn't make sense to replace your entire system just because its warranty period has ended, it's worth considering the lifespan of more expensive components. Replacing your system before failures occur can help you to dodge these costly replacements.

2. Repairs Can Pile Up

Warranties protect you from unexpected early breakdowns, but outside of your warranty period, you will be approaching the expected lifespan of most of the components in your system. For example, both the compressor and evaporator coils tend to last as long as your AC, about 15-20 years. Once one fails, the other may be close behind.

Unfortunately, a lack of maintenance can make these issues even worse. If you have neglected annual inspections, cleanings, or other essential maintenance tasks, then component failures can often occur one after another. It can be easy to find yourself in a situation where the nickel and dime costs of individual repairs eventually exceed the price of an entirely new system.

3. Newer Units Are More Efficient

Central air conditioning systems use the Seasonal Energy Efficiency Ratio (SEER) as a measure of energy usage. SEER rates the overall efficiency of the unit throughout the season, and a higher SEER rating means a more efficient system. Depending on your current annual AC energy costs, upgrading to a higher SEER unit may save a substantial amount of money.

In general, you can expect newer AC units to have a SEER rating of 15 or greater . If you are curious about the rating of your current system, you should be able to find a sticker on the casing of your outdoor condenser unit. An improvement of even a few points might offer you a savings of a hundred dollars or more per year on your utility bills.

4. You Will Avoid Downtime

There are more than just monetary advantages to replacing your old system, of course. As your current system ages, you will suffer more and more downtime as parts fail. Georgia isn't known for its cool summers, so going without air conditioning can be miserable. Even worse, breakdowns can be unexpected, and you may be waiting several days for repairs during the busy season.

By upgrading a system that's already reaching the end of its lifespan, you're more likely to have uninterrupted service throughout the summer. With proper maintenance, your new system will continue to provide you with efficient service for years to come.

If you think it might be time to give up your old air conditioner, then Parks Davis Air Conditioning & Heating can set you up with a new, energy-efficient system. Get in touch to schedule an evaluation of your old system today!

Maintain Your Heating and Cooling System with These Tips

Thu, 23 Jan 2020 18:27:03 GMT

Maintenance is vital for your HVAC system. Not only does regular maintenance keep your unit in good working order, it uncovers small issues before they become huge problems. It prolongs the life of your system and even saves you money.

While professional maintenance is recommended, you're still encouraged to do your part. By checking out and maintaining your system between regular checkups, you can promote the life and health of your HVAC system.

Establish a Maintenance Plan

You need a plan before you can do anything successfully. The same is true of HVAC maintenance. To run smoothly, your HVAC system needs timely and routine maintenance. So, it's important to establish a maintenance schedule to ensure it gets done.

What all goes into a maintenance plan? First, you should plan to replace your air filters every 30 to 90 days . This is also a great time to look clean your drain line and look over the unit for grime buildup and/or any potential issues.

Second, you should clean your unit and remove debris and vegetation annually. Third, you should establish a professional inspection at least once per year. Ideally, you want to have the heat portion of your system checked in the fall and the cooling portion of your system checked in the spring.

Change Your Filter

Clogged air filters can reduce air flow and make your unit work harder, resulting in damage. The fan motor and heat exchanger are especially vulnerable under these circumstances. Dirty air filters also allow dirt to get into and build up in your system, which can lead to breakdowns and dirty ducts.

Since you should change your filter every 30 to 90 days, you may think once every three months is plenty. However, you may want to change it more frequently, such as once a month. If you smoke in your home, have pets, engage in a dusty hobby, have a large family, or anything else that may cause your air filter to get dirty faster, you should change it more frequently.

Clean Components Regularly

When anything is allowed to get dirty and grimy, it has a higher chance of breaking down. Certain components in your system get dirtier than others. Your outdoor A/C condenser unit, for example, is at the mercy of Mother Nature. Dead leaves, mud splatters, animal droppings, and any other messes should be cleaned as soon as you become aware of them. If nothing like this happens to your unit, clean it annually.

Since they retain moisture, evaporator coils have a tendency to attract dust, which can turn into a sticky goo after time. Check your coil each time you change your air filter and clean it as necessary or once a year, whichever comes first.

Clear Clogged Lines

The condensation drain line on your unit removes the excess moisture that builds up on your evaporator coil. On occasion, this line can get clogged or develop mold and mildew in it. Inspect your line once a month or whenever you change your air filter.

If you notice mold or mildew, clean your line by passing a solution of warm water and bleach through it. If you can prevent mold and mildew from taking hold, you will reduce the chances of your line getting clogged.

When's the last time your system had a thorough inspection? If it's been more than a year, contact Parks Davis Air Conditioning & Heating to make an appointment. In the meantime, keep following your HVAC maintenance plan and look over your system yourself to see if you can see any potential issues. Your HVAC system will thank you for it.

4 Signs You May Need to Replace Your Air Conditioner

Tue, 12 Nov 2019 18:51:19 GMT

Many people would consider their central air conditioner to be the most important appliance in their home. However, your air conditioner is vulnerable to wear and tear and will eventually need to be replaced like any other appliance. Here are four signs you may want to replace your air conditioner.

1. Inconsistent Cooling

Your central air conditioner is meant to cool every room in your home evenly. If you notice that some rooms are staying warmer than others, there could be a number of causes. In the best case, you system may have a blockage or leak in the ductwork that a professional duct inspection could solve. However, inconsistent cooling can also point to a mechanical problem with your air conditioner.

One mechanical failure that can lead to an unevenly cooled home is a faulty blower motor. If the motor is no longer able to create the needed amount of air pressure, the first place you will notice a problem is in the rooms furthest from the blower. These rooms take the most effort for the blower to deliver air to and will lose airflow first when the system loses efficiency.

2. Excessive Noise While Running

Excessive noise while your air conditioner is running can be a sign that a moving part is failing. An HVAC technician will need to examine the unit to pinpoint the cause of the noise, but certain problems will always create similar sounds. A grinding noise can be caused by a faulty condenser motor, and buzzing is usually the result of an internal electrical issue.

While a noisy air conditioner should never be ignored, some sounds are less cause for concern. A rattling sound may simply be caused by loose screws or panels on the casing, and a squealing sound may be caused by a loose fan belt. If mechanical failure is determined to be the culprit, replacing the air conditioner will often be more cost-effective than repairing it.

3. Increasing Energy Bill

A healthy central air conditioner will maintain similar energy costs with the same usage from month to month. If you notice an unexplained increase in your energy bill over the course of a few months, it could be caused by your air conditioner losing efficiency. This is almost certainly the case if your air conditioner is exhibiting frequent performance problems.

You should observe the way your energy costs trend over time before you conclude that your air conditioner is to blame. Short-term usage changes, such as when you have guests over that use the air conditioner more often, can have a greater impact on your bill than you would expect.

4. System Nearing End of Life

No matter how well you maintain your air conditioner, it will eventually reach the end of its effective lifespan. Central air conditioners will last 10 to 15 years on average, but the loss of efficiency makes many homeowners consider replacing them around the 10 year mark. Replacing your unit within this time frame can help you avoid unexpected breakdowns.

If you are moving into a new home that already has a central air conditioner installed, you should always determine the age of the unit. You can usually find a model number for the air conditioner on a label on the outdoor condenser. Search for this model number online to find the date it was manufactured so that you have an idea of when it will need to be replaced.

Replacing your central air conditioner is an excellent opportunity to upgrade to a modern, high-efficiency unit that can greatly reduce your overall energy costs. If you are in the market for a new central air conditioner, contact us at Parks Davis Air Conditioning & Heating so we can help you find the perfect new cooling solution for your home!

HVAC Filters: What You Need To Know

Tue, 23 Jul 2019 19:09:27 GMT

As a homeowner, you may know that your HVAC system's air filter needs to be changed regularly, but you may not know how often or what type you should purchase from the home improvement store. If you are buying a home for the first time and have never even needed to worry about something like this before, how do you know what filter will best suit your needs?

When it comes to residential HVAC filters, there are numerous options available on the market, so choosing the right one for your home and family is important. Prior to purchasing a home air filter, some things to consider include:

Choosing the appropriate size filter.
Being familiar with the different kinds of filters.
Checking the minimum efficiency reporting value.
Knowing the frequency level at which your filter should be changed.

Keep reading to learn about all of the above.

Choosing the Appropriate Size Filter

HVAC filters come in a variety of sizes, and filters tend to work best when they have a snug fit. Once installed, the filter may not be the right size for your HVAC system if there are gaps around the frame. The size of the filter can usually be found on the side of the filter frame, so make sure to check for this information before purchasing a filter.

Being Familiar with The Different Kinds of Filters

There are multiple types of filters for your HVAC systems, all of which vary in maintenance requirements and performance levels. As a general rule of thumb, filters perform best when they are new and clean, though some filters last longer than others because of the way they are made.

Disposable Fiberglass Air Filters – These filters are designed to collect larger particles like dust, lint, and debris. Fiberglass filters are the least effective out of all the filters and are best used in homes without pets and individuals without health conditions or allergies. These filters are the most economical.

Disposable Pleated Air Filters – These filters are designed to collect small and large particles like spores and mites. These filters will cost slightly more than disposable fiberglass filters, but they will also need to be changed more frequently.

Reusable Electrostatic Air Filters – These filters have charged electrostatic fibers and are considered 10 times more efficient than their disposable counterparts. These filters are washable, which means they don't need to be replaced as often as disposable filters—possibly only every 5 to 10 years.

HEPA Air Filters – These high-efficiency filters are designed to be the most effective at removing both large and small particles, including pollen and mold. They are most commonly used in hospitals and similar sterile environments, but they can be used in residential settings. A HEPA filter is good if a household member suffers from allergies. These filters are also the most expensive of the bunch.

Checking the Minimum Efficiency Reporting Value

Air filters receive a Minimum Efficiency Reporting Value (MERV), which is a rating that informs customers of how well a filter traps particles. Residential air filters receive a rating between 1 and 13, and the higher this number is, the more efficient the filter is. It is recommended to purchase an air filter with a rating of at least six.

Knowing the Frequency Level at Which Your Filter Should Be Changed

Regardless of the type of filter that you select for your home, disposable filters require changing and washable filters require cleaning as soon as the filters become dirty to avoid air flow becoming restricted. In general, though, air filters should be changed every three months at a minimum, possibly more frequently during heavy seasons (summer and winter) and if you have pets or allergy suffers in the home.

If you run into any problems with your air filter or HVAC system, give us a call at Parks Davis Air Conditioning & Heating and we'll be happy to help.

4 HVAC Questions for Eco-Conscious Homeowners

Mon, 27 May 2019 19:26:22 GMT

As an eco-conscious homeowner, you may feel that the environmental impact of your AC unit is regrettable, but necessary. After all, you can't be expected to face sweltering summer heat, which can even be hazardous to your health, when an AC unit is sitting there waiting to be used.

Fortunately, if you put your mind to it, you can still cut back on your AC system's environmental impact without forgoing the cooling it provides. Here are four questions to ask in your pursuit of lower-impact AC.

1. What Powers Your HVAC System?

Today's homeowners have many different options for reducing their AC's ecological footprint by avoiding fossil fuel use. Geothermal systems, for instance, cycle the excess heat in your home far underground and cool your house that way. But even if you have a traditional AC unit, all is not lost.

Installing solar panels to offset your HVAC system is a surprisingly affordable option nowadays. You may only need a couple of panels as opposed to an entire array, and you may not even have to mount them on your roof. Or you may be able to find a power company in your area that offers solar- or wind-based power.

2. How Can You Increase Efficiency?

Whether you use fossil fuels to power your AC or you use solar power, no energy is truly free. But no matter the power source, the more energy you save, the lower your ecological footprint. So a more efficient AC unit, as a rule, is going to be better for the Earth.

If your AC use has been on autopilot, now is the time to take a step back and look at increasing efficiency. For example, you can use a smart thermostat to track when you really need the AC to be on and cut back on cooling when it's not needed. Or you can add some of the following passive cooling measures to reduce the load on your AC system:

Open the windows in the evening or mornings if the temperatures are cool
Add a radiant barrier or attic insulation
Shade part of your house with landscaping
Coat your roof with a cool roof coating

These measures can help reduce the amount of extra heat added to your home each day, making your AC unit's job easier so that it uses less power.

3. Could Your System Use Extra Maintenance?

Another way you can make your unit's job easier is by taking great care of it. Even if you already schedule professional maintenance annually, home maintenance can make a difference as well. Try caring for your AC system with the f ollowing tasks:

Check air filters more frequently and change them when they start to get dirty
Keep plenty of open air space around the AC unit
Keep all grass and plants around the unit trimmed to under six inches tall
Check the condenser coil fins to make sure they're not flattened down
Vacuum away any debris stuck in the sides of the unit
Have your AC technician wash the AC coils twice a year

Better than average maintenance will help your AC unit stay efficient.

4. What Should You Look for In a Replacement?

When you do replace your AC unit, you'll want to make sure it's as eco-friendly as possible. But what can you look for when evaluating how eco-friendly the unit is?:

Look for the highest SEER rating you can find (high ratings mean higher efficiency)
Research the company to see if they have eco-friendly business practices like carbon offsets or green packaging
Look for a unit that uses a more eco-friendly refrigerant, such as R-290, which has less potential for global warming

A replacement unit that meets these criteria will be a much more eco-friendly choice than a run-of-the-mill unit.

These four questions will help you to assess how eco-friendly your current AC use is and how you can reduce your AC's environmental footprint. For more information about AC maintenance or repairs, get in touch with Parks Davis Air Conditioning & Heating today.

3 Most Common HVAC Issues to Avoid

Tue, 26 Mar 2019 19:38:07 GMT

The HVAC system is one of the most expensive investments in a home, and in a warmer climate like Georgia, it's essential. Homeowners have to be vigilant about air conditioner maintenance to avoid costly repairs, not to mention the discomfort in the home if the system fails.

Fortunately, you can keep a lookout for potential issues and catch them before they become a problem. Here are some of the most common issues to watch out for.

1. Insufficient Drainage and Clogs

An HVAC system has a system of drainage to remove the excess moisture that builds up. In a functioning system, the moisture turns to condensation, which is sent through a system of pipes and drained outside the home. From time to time, the drainage system can clog and cause the moisture to back up into the system.

The moisture can then get into other parts of your air conditioner and can even cause water damage to other parts of your home, such as ceilings, walls, and floors.

To prevent this problem, you should have the condensation drains checked regularly. You should have your overall system checked by a professional a couple times a year for regular maintenance.

If you do not typically schedule maintenance checks, at least have a technician come to check the drainage systems, especially if you notice any water damage or dripping from your air conditioner inside the home. Not doing so could ultimately cost you a lot more money than a typical maintenance check.

2. Fans Not Blowing Properly

The HVAC system has two fans that work together to get the air into your home, so they should work efficiently. One fan pushes the air through the evaporator coils and circulates it throughout your house. The other fan, outside in the condenser unit, removes the warm air from the unit so the system does not overheat.

If either of these fans malfunctions or get too dirty, your HVAC will not work as well as it should. The system could quit working altogether if the fans are in particularly bad shape. Check the fans by looking at and listening to them.

You can easily check the outdoor fan by looking at the condenser unit. If you see that the fan is not spinning when the air is on, turn off the air conditioner and call your HVAC technician, as you do not want to burn up the unit.

You can tell if the fan inside is not working just by listening. When you turn on the air conditioner, the fan will start. If you do not notice a sound when the air cycles on, there is a chance the fan is not working. This is another issue for your HVAC technician to check out.

3. Leaks from The Refrigerant

Another common issue for HVAC systems is leaking refrigerant. The air conditioner requires a certain level of refrigerant to create cool air. The system needs a certain amount of refrigerant to cycle through the coils, absorbing heat from the air and creating cold air for the house.

Over time, the coils can crack or leak, causing the refrigerant to leak out. If you notice that the air flowing through the vents of your home is warm when you have the thermostat set low, chances are you have a refrigerant leak. Not only will a leak make your home uncomfortable, but you will also have a dangerous chemical leaking outside. An HVAC technician can find and repair the leak.

If you notice any of these issues, please contact Parks Davis Air Conditioning & Heating . Our experienced HVAC contractors will come to check your air conditioner for all potential problems and make the necessary repairs.

4 Signs Your Ducts Require Attention

Wed, 23 Jan 2019 19:45:44 GMT

Many homeowners prefer the ease and luxury of forced-air heating and cooling. Like any major system, you need to keep your HVAC system well-maintained and cleaned to ensure efficiency. But forced-air systems use a series of ducts that are often neglected by homeowners during regular maintenance. If you haven't had your ducts checked in a while, you may start to notice these four signs.

1. The House Isn't Getting as Cool/Warm as You Want

Forced-air heating and cooling systems are so desired because they can usually heat or cool your home quickly and effectively. One glaring sign something is wrong with your system is it simply isn't as effective at cooling or heating as it used to be.

Many problems can cause the system to not function as well, such as a dirty filter, dirty coils, low refrigerant levels, slow fans, etc. If your system seems to be in good condition, however, the problem may be the ducts.

Your ducts may simply be dirty, but in many cases, reduced heating/cooling efficiency is caused by holes and gaps in the ducts, which allow heated/cooled air to escape. To correct this problem, a professional can repair any damage and reattach any detached duct segments.

2. Your Heating and Cooling Bills Are Rising

Even if you can get your home as warm or as cool as you'd like, you may be spending a fortune to do so. Rising heating and cooling bills usually indicate something is wrong with the system. This problem can also be caused by holes in the ducts. In order to replace the lost air, you'll have to turn up or down the thermostat, which means more energy and money.

Another reason energy bills may be rising is dirty ducts. Dust and various bits of debris, such as animal hair, can get inside the ducts. If too much debris gets in the ducts, it may reduce airflow because the pathway is narrowed. Again, this causes you to use more energy to keep your home comfortable.

3. The Indoor Air Quality Has Dropped

Dust can also affect your indoor air quality. If a lot of the dust, allergens, pollen, pet hair, or other debris remains in the ducts, some is expelled into the living space each time the system is used. This can cause red and itchy eyes, sneezing, and coughing. If you have allergies or breathing problems, it may cause asthma attacks, rashes, or breathing complications.

In rare situations, if you have a rodent infestation in your ducts, the rodents may also cause chemicals and odors from droppings to affect your breathing air. Lastly, if you have mold in your ducts, it can lead to nasal stuffiness, throat irritation, and eye irritation. You must get the ducts cleaned to remove the dust, identify any pests, and clean any mold.

4. The System Keeps Breaking Down

The last sign that may indicate a problem with your ducts is frequent breakdowns. If you've been maintaining your system but breakdowns are still frequent, check the ducts. Dirty ducts can put extra strain on the system, causing it to wear down sooner so it needs more frequent repairs and early replacement.

This happens because the system doesn't realize the ducts are narrowed from dust. Therefore, it continues to push the same amount of air through the ducts. With less space, however, the system is forced to push harder to expel the air, which not only increases costs, but also increases wear and tear on the system.

Ducts can cause many problems in forced-air heating and cooling systems, so you must remember to keep them well-maintained. Dust and gaps can cause the system to work less efficiently and effectively, which costs you more money.

3 Ways to Protect Against Carbon Monoxide

Thu, 22 Nov 2018 19:56:15 GMT

This Is a Subtitle for Your New Post

Gas furnaces provide an effective and economical way to keep your home cozy during the winter months. Yet your furnace can also become the source of inefficiency and health threats if not properly maintained. In particular, an ill-maintained furnace can produce dangerous levels of the gas known as carbon monoxide.

Carbon monoxide can lead to death if present in high enough quantities in your home's air. For that reason, homeowners must take proactive steps to minimize the risks of carbon monoxide exposure. If you would like to learn more about some of the most effective strategies, keep reading. This article explores three effective ways to protect against carbon monoxide exposure.

1. Have a Technician Analyze Your Combustion

A perfectly working furnace — in other words, one that burns up every last bit of gas that flows into it — produces no carbon monoxide at all. Instead, all of the gas burns up, producing three things: heat, water, and carbon dioxide. Yet when combustion does not occur completely, not all of the carbon in the gas gets oxidized.

This incomplete oxidation leads to the formation of carbon monoxide gas. By law, flue gases can contain carbon monoxide in quantities of no more than 400 parts per million . Yet a furnace suffering from an incorrect air-to-fuel ratio may produce considerably more carbon monoxide as the result of incomplete combustion.

Because carbon monoxide has an odorless, colorless nature, it's not always easy to detect. Fortunately, an HVAC technician can measure carbon monoxide levels through the process known as combustion analysis. Combustion analysis gives the contractor a detailed picture of all of the substances found in your furnace's exhaust gas.

By analyzing this data, the technician can determine whether or your carbon monoxide levels remain in safe limits. Furthermore, the technician can use this information to make changes to your furnace's combustion settings. Such changes will not only reduce the amount of carbon monoxide produced but also improve the overall energy efficiency of your HVAC system.

2. Have Your Furnace Inspected Regularly

Carbon monoxide can present a threat even when your furnace's combustion remains within acceptable limits. Ideally, no matter how many exhaust byproducts form during combustion, none of them should get into the air of your home. Instead, the carbon monoxide and other gases should pass upward and out of your home through the exhaust flue.

Unfortunately, as an HVAC system ages, it often develops problematic corrosion, especially inside of the component known as the heat exchanger. The heat exchanger consists of a curving metal tube through which the hot exhaust gases flow. As air from your home circulates around the exchanger, it absorbs the heat. The dangerous gases, meanwhile, remain trapped inside.

If a heat exchanger becomes corroded to the point that holes form in its sidewalls, exhaust gases begin to leak out into your air. As a result, carbon monoxide may end up in your home. To prevent this issue, have your furnace system professionally inspected for signs of damage on a regular basis.

3. Install Carbon Monoxide Detectors

As noted above, carbon monoxide has no detectable color or scent. This quality makes carbon monoxide especially deadly, since homeowners cannot detect the gas using their senses. For this reason, you must equip your home with carbon monoxide detectors. These detectors differ from regular smoke alarms, which cannot register the presence of carbon monoxide.

For best results, install at least one carbon monoxide detector on every floor of your home — including the basement, if that's where your furnace resides. Ensure each detector receives equal airflow. Install detectors at knee height. Since carbon monoxide mixes with air, it doesn't rise in the same way as heated smoke.

Carbon monoxide may be a deadly gas, but homeowners can keep themselves safe by following a few key tips. For more information about how to keep carbon monoxide at bay, please contact the HVAC experts at Parks Davis Air Conditioning & Heating.

AC Not Cooling? Things You Can Check Yourself

Mon, 01 Oct 2018 20:02:53 GMT

As a homeowner, few things are more frustrating than one of your major home components not working properly, like an HVAC malfunction. HVAC malfunctions could involve the entire system quitting altogether, but something is still clearly wrong if the system is simply not functioning as strongly as it should. Neither situation is ideal and needs repair as soon as possible.

If you notice your air conditioning is not cooling your home, the problem could be simple or complicated. Many times, you can diagnose and fix the problem yourself. Here are some things you can try before you call the professionals.

Clean Up Around Your Outdoor Condenser

When your air conditioner is not working like it should, take a look at your outdoor unit. The condenser is the brains of your HVAC system, so proper maintenance is crucial if you want the system to function properly.

One of the biggest issues for outdoor condenser units is blockage by debris. Grass, leaves, dirt, and other debris can quickly build up outside the grates of the unit. The unit needs full air flow to work, and the buildup of the debris prevents the air from getting inside. Grass can also grow around the outdoor condenser unit, especially during the spring and summer months.

To prevent limited air flow, simply take time on a regular basis to clean up around the condenser. Trim the weeds and grass growing around the unit each time you mow your lawn. Rake away grass, leaves, and sticks that may have fallen from nearby trees. Also, look down into the casing of the condenser to make sure nothing is stuck inside and preventing the fan from turning.

Check Your Electrical Breaker Box

Another item you can check is whether or not your air conditioner has a full connection to an electrical source. Although you may think you’d easily notice if the power is not properly running to the HVAC, the truth is that several breakers power the whole system, and only one breaker has to trip for the air conditioning portion of the system not to cool properly.

Go to your home's electrical breaker box. You should have more than one breaker labeled HVAC, air conditioner, or the like. Turn them all to the off position, then back on. Give the system a few moments and see if it makes a difference.

Incidentally, many HVAC systems require all components to have the power on to operate. Even if you are not using the heating component, the breaker still needs to be on. If the heating component's breaker is off, turn it on and your air should work again.

Check Your Thermostat

If nothing has worked yet, the next place to check is your thermostat. If your thermostat is digital, look for a blank readout, any readouts blinking, or anything else seemingly out of the ordinary. This could just be an issue as simple as changing the battery in your thermostat. If a new battery does not do the trick, your thermostat may have gone out. This means you need a new thermostat installed.

Depending on your comfort level in doing home maintenance, you can install a new thermostat as a DIY project. However, it is best to have a licensed technician do the job for you since many electrical tie-ins are necessary.

If none of these options help your air conditioner issue, you need to call in the professionals for help. The problem could be due to a variety of reasons, so a proper diagnosis is essential.

3 Ways to Reduce Your AC Bill This Summer

Wed, 25 Jul 2018 20:12:54 GMT

A great air conditioner can make your home feel crisp and cool, but unfortunately, that comfort comes at a price. Since air conditioners can be expensive to run and repair, it pays to do what you can to reduce heat gain inside of your home. Here are three ways to reduce your air conditioning bill this summer and why your HVAC system will thank you.

1. Cook Outside

As you use your oven and simmer, sauté, and flambé, you heat up your home and fill your indoor air with microscopic pollutants. Steam, cooking grease particulates, and even the cleaners you use afterwards can fill the air with pollution.

According to the United States Environmental Protection Agency (EPA), these pollutants can make your home's breathable air even dirtier than the stuff you breathe outside.

As your HVAC system circulates air through your home, these particulates can accumulate in air ducts and filters, making your AC unit run harder than it needs to.

Cooking inside can also dramatically increase indoor temperatures. In fact, the Occupational Safety & Health Administration (OSHA) has reported that the temperatures in front of indoor grills can reach upwards of 105°F - 110°F, prompting your air conditioner to turn on more frequently than you might like.

Fortunately, you can prevent both of these problems by cooking your meals outside on the barbecue grill. In addition to providing tasty grill marks on your meats and vegetables, grills can be fitted with silicone or metal trays that allow people to sauté ingredients or cook delicate foods like fish.

2. Consider Repainting Your Home

You might love that dark gray stucco that covers your home's exterior, but it might be baking the inside of your place. Homes that are painted dark colors have been shown to absorb as much as 70% to 90% of the radiant heat generated by the sun, creating a conduction effect that warms up your home.

On the other hand, lighter colors of stucco, siding, and brick tend to reflect the radiant heat from the sun, keeping your home cooler and reducing the load on your HVAC system. If you are unhappy with the color of your house and your energy bill, consider painting your home's exterior to keep your place cooler.

Some homeowners take this energy-saving principle a step further by investing in cool roofs, which are made from light-colored materials. According to Energy.gov, these roofs stay about 50°F cooler than traditional dark roofs, extending the life span of the shingles and allowing less heat into your home.

3. Switch Up Your Yard

You might not care too much about how pretty the area around your outdoor HVAC unit looks, but with a little careful planning, you could beautify the space and help your air conditioner to run more efficiently.

Shade can cool the air by as much as 10°F-15°F claims SunSentinal. So planting a tree that shades your outdoor unit can improve your air conditioner's efficiency by as much as 10% , lowering your monthly energy costs. If you are concerned about things like falling twigs and leaves getting lodged in your HVAC fins, consider installing a shade sail or a retractable awning above your unit.

On days when the weather forecast is hot and sunny, make sure your shade sail or awning is fully extended so it can provide the most shade possible. When the air is cooled slightly before it enters your home, it will take less energy to bring the air to the set temperature.

If you have made some changes around your home and you are still struggling with high energy bills, give our team a call today. Here at Parks Davis Air Conditioning & Heating , we can diagnose and resolve indoor climate control issues, helping you to enjoy a comfortable experience. With our fast service and complimentary quotes, you won't have to wait long to make your home better.

AC Refrigerant Leaks: What Every HVAC Owner Needs to Know

Fri, 01 Jun 2018 20:25:53 GMT

Refrigerant plays a crucial role in the optimal performance of your air conditioning (AC) system. A slight reduction in the AC's refrigerant can lead to high electricity costs, cumulative system damage, and overall discomfort in the home.

It is important to anticipate refrigerant leaks in order to fix the problem before it is too late. Here's a quick guide to help you get started.

Causes of Refrigerant Leaks

Several factors could cause a Freon leak in your AC. The most common causes include aging, corrosion, and improper installation of the unit.

Aging

Over time, the AC piping can succumb to wear and tear and begin to leak. The outside unit, which is exposed to weather elements and environmental contaminants, could also rust around the joints, leading to leaks.

Corrosion

Your AC's copper tubing may be subjected to corrosion. Often, formic acid or formaldehyde is the culprit. Formaldehyde is present in almost all homes. This chemical compound not only compromises indoor air quality, but it can also eat away copper tubes in the indoor AC unit.

Formic or formaldehyde corrosion tends to cause multiple leaks, which can result in expensive repairs or replacement of the coils. Find out if your HVAC contractor can replace the copper coils with corrosion-resistant aluminum coils.

Bear in mind that extensive corrosion due to lack of regular maintenance may require complete replacement of parts of your AC system.

Improper Installation

Even a new AC unit can leak refrigerant if the unit vibrates excessively from improper installation. In addition, any damaged parts of the AC unit could cause Freon leaks.

Signs of AC Refrigerant Leaks

Early identification of a refrigerant leak can mitigate the need for expensive repairs or replacement. There are several telltale signs of a Freon leak.

Energy Bill Is Higher

If your energy bills spike up suddenly, a defective AC unit could be the culprit. Adjusting your thermostat downward to cool your home faster can increase energy usage, and the costs can add up fast.

House Takes Too Long to Cool

During the warmer months, the refrigerant absorbs indoor heat and releases it outside. If your AC is taking longer than usual to cool the house, it is likely that the refrigerant levels are too low.

Vents Not Releasing Cool Air

Place your hand on the AC vents to check the temperature of the air being released. If the air is not cool, it is a sure sign of depleted refrigerant.

Ice Forms on the Coils

Low levels of refrigerant will prevent the coils in the indoor unit from absorbing enough heat. This can cause the coils to freeze over. You will only likely notice the problem when the ice melts and drips on the floor.

Indoor Unit Produces Unusual Sounds

Look out for a hissing sound in your indoor AC unit. This sound is likely coming from corroded copper coils that carry the refrigerant throughout the system. A louder bubbling sound could be a sign of extensive leakage.

Frozen coils could be a sign of a much larger issue such as a defective compressor. Have an HVAC technician check your AC unit immediately to curtail further damage.

Remedies for Refrigerant Leaks

With preventative maintenance, you can avoid refrigerant leaks and the associated repair or replacement costs.

Small leaks in the AC unit can be repaired easily. In case of extensive damage, your HVAC technician may recommend replacing the evaporator coils entirely.

An AC system that won't work can be distressing, especially during the blistering summer months. Avoid quick fixes such as attempting to fill up the refrigerant, as this could cause irreversible damage to your system. Instead, call a professional HVAC technician if you notice any signs of a leak.

AC Maintenance Tips

Wed, 04 Apr 2018 20:38:39 GMT

An air conditioners usage accounts for a sizable portion of your whole home's energy use. Your entire HVAC system can consume almost half your whole home's energy use, according to the U.S. Department of Energy. This makes maintaining your AC absolutely essential.

A dirty, dust-filled or debris-clogged air conditioner slows down your system, making it work harder just to keep your home cool and comfortable. From pet fur-filled air filters to the vents that push air from the air conditioner into your rooms, making sure that each component is running in top shape will lighten the load, decrease your overall energy use, and save you money on electricity costs.

What do you need to know about air conditioner maintenance? Take a look at the following tips to make sure that your system runs at peak performance.

Schedule Appointments in Advance

Waiting to schedule maintenance until your AC system shuts down or starts having problems isn't the most helpful way to service your air conditioner. A pre-season check-up, scheduled before you turn on the AC for the warmer months, is an easy way to make sure that worn parts get the repairs they need. It also offers the opportunity to have your system professionally cleaned before using it.

Instead of days, weeks, or months of forcing dusty, pet hair-filled air into your home, having the air conditioner serviced early on can save you from allergies, asthma attacks, or other reactions to potential contaminants that are caught in the system.

Keep in mind that the beginning of the summer months is a busy time for HVAC service providers. Waiting until the first air conditioning-worthy day to call and schedule an appointment may mean that you have to wait. Think ahead, reviewing the future forecast, and schedule an appointment before the weather starts getting warm.

Regularly Clean Your Air Filters

While a task such as cleaning the coils is something that a professional should do, you may be able to maintain the air filters with minimal assistance.

The first step is to find out what type of air filter your system uses and where it is located. Both of these depend on the model of your HVAC system. Some air conditioners have replaceable filters that you take out and toss, while others have reusable ones that require cleaning.

Fiberglass, polyester, and pleated air filters are all relatively inexpensive but require full replacement. Electrostatic air filters are washable, meaning they are cleanable and replaceable.

During your next AC check-up ask the technician to show you where the filter is, what type it is, and how to either replace or clean it. You should clean or replace your system's air filters at least once a month, especially if it is in constant use. A once-a-year change or cleaning during a pre-season check-up isn't enough - especially if you have pets or a respiratory condition such as allergies or asthma.

Don't Underestimate the Value of Professional Help

Your routine AC maintenance appointment will include much more than simply clearing out a clogged filter. This appointment may also include cleaning other debris-filled areas, a preventative evaluation to check for broken or worn parts, an assessment of the ducts for leakage, a refrigerant check, and a thermostat inspection.

If your air conditioning system requires additional services at the time of the maintenance appointment, the technician will recommend them at this time. This may include the replacement of worn parts or repairs that can help your system to work more efficiently.

How Can You Tell if Your Ducts Need to Be Cleaned? An FAQ About Duct Cleaning Services

Thu, 01 Feb 2018 20:48:16 GMT

Duct cleaning is a service that many people know little about. Knowing what duct cleaning is and how it can benefit you can help you take care of your HVAC system. This FAQ is designed to help homeowners decide when it's time to consider professional duct cleaning services for their home.

What Causes Ducts to Get Dirty?

Ducts get dirty when dusty air circulates through the house. At any given moment, your home's HVAC system may contain dust, pollen, dirt, mold, and mouse droppings. As the system runs, this debris becomes trapped along the walls of the ducts. This layer will build slowly over time.

How Can You Tell if Your Ducts Need to Be Cleaned?

There are a variety of warning signs that you may notice when your ducts need to be cleaned. Watching out for these warning signs can help you decide when it's time to contact a duct cleaning professional.

Your HVAC System Causes Allergy Symptoms

If you or members of your household experience allergy symptoms when the HVAC system is running, this is an indication that the HVAC system is circulating dust, pollen, and other allergens through the home.

Your Furnace or Air Conditioner Seems to Smell

If your HVAC system produces a noticeable odor when it runs, especially a moldy-musty smell, this could be the result of mold spores in the ducts. Cleaning the ducts can help you eliminate these odors.

Your HVAC Air Filter Gets Very Dirty Very Fast

Your home's HVAC filter should be changed every three months or more frequently if it becomes very dirty. If your air filter gets very dirty after only a month of use, this could be a sign that your ducts are in need of cleaning.

If you have concerns about your home's ducts, remove one of the vent covers and look inside with a flashlight. If the inside of the duct is covered with a layer of dirt and grime, this is an indication that your ducts are in need of cleaning. For a more official diagnosis, contact your HVAC repair and duct cleaning company.

How Often Do Ducts Need to Be Cleaned?

Ducts need to be cleaned when they're having a negative impact on indoor air quality. This can vary from one household to the next, depending on the homeowner's typical HVAC maintenance habits. When your HVAC system starts to display the signs above, contact an HVAC maintenance company. In many households, the ducts need to be cleaned every three to five years.

How Can You Prevent Your Ducts from Getting Dirty?

The best way to prevent your HVAC system from getting dirty is by changing the air filter on a regular basis. Look for the filter in the slot between the return air duct and the blower. Remove the filter and take it to a hardware store to find a replacement. Turn off your HVAC system while there is no air filter in the compartment. When a new air filter has been found and put into its place, you may turn the HVAC system back on.

You can also prevent your ducts from getting dirty by getting an HVAC system tune up on a regular basis. Your HVAC professional can inspect your ducts for leaks that can also result in dust entering the ducts. Contact your HVAC professional to schedule a tune-up at least once annually. During the tune-up, your HVAC professional will clean the components of the furnace and air conditioner and check the ducts for leaks.

6 Benefits of Commercial HVAC Maintenance

Sat, 16 Dec 2017 20:57:10 GMT

The daily responsibilities of owning or managing a business sometimes make it easy to overlook the importance of scheduling for routine commercial HVAC maintenance. However, the system that heats and cools your commercial building plays a big role in the success of your business operations.

A faulty HVAC system cannot properly regulate the temperature in your work environment, and letting minor issues go too long can lead to more expensive repairs. As you review your company's maintenance plan, keep these benefits of commercial HVAC maintenance services in mind.

1. Reduce Energy Costs

HVAC systems require a large amount of energy to operate, and this can significantly impact your company's budget. However, regular maintenance reduces the load on the unit so that it operates more efficiently.

From lubricating parts so that there is less friction to promoting better air flow, HVAC services make it easier for a consistent temperature to be maintained in the building - without the unit cycling too frequently.

2. Prevent Major Breakdowns

Regular commercial HVAC maintenance includes services that correct minor issues before they spiral into a complete breakdown. For instance, repairing a minor refrigerant leak prevents you from having to potentially shut down your business if the unit suddenly stops blowing cool air.

3. Extend the Life Span of The Unit

Commercial HVAC systems all have a shelf life, and replacing an entire unit is a major expense in your company budget. Although every system will eventually need to be replaced, you get more out of your initial investment by extending your HVAC system's life span.

4. Avoid Costly Property Damage

A clog in the HVAC system's drainage lines can lead to water leaks that create serious water damage. Because many systems are located in hidden areas of a commercial building, substantial damage can occur before the leak is noticed.

During a routine maintenance visit, the entire drainage system is checked for clogs that fill up drip pans and cause overflowing water to spill on to building materials. If a clog is found, the system is cleaned out and any faulty components are replaced so that you can protect the structural integrity of your commercial building.

5. Maintain a Healthy Environment

Every business has a responsibility to do their part to protect the health of any customers and employees that spend time in the building. Unfortunately, poor air quality is a significant cause of allergies and illnesses.

HVAC systems help to control humidity in indoor environments, and a poorly functioning system can create an environment that promotes mold growth. Therefore, routine maintenance checks help to keep mold and fungus levels down in commercial buildings.

The air filters in the commercial unit are also designed to trap dirt and debris that contributes to indoor allergies. Make sure that a member of your building's maintenance team checks the air filters according to the recommended schedule. Then, arrange for professional services to make sure they function properly.

The air ducts that connect to the system should also be checked on a routine basis to determine if there is a need for cleaning. Over time, small particles such as mold spores, dust and rodent droppings can get into the ductwork. By cleaning the ducts, you effectively reduce the airborne allergens in the building.

6. Keep Indoor Temperatures Consistent

When your commercial system is running efficiently, the temperatures in your business environment should stay fairly consistent. Consistent temperatures increase employee productivity and encourage customers to visit the building. A professional HVAC technician can also adjust the thermostat settings for optimum efficiency.

Getting Your Furnace Ready for Winter

Wed, 04 Oct 2017 21:06:30 GMT

Having access to a functional furnace ensures that you will be able to maintain a comfortable indoor temperature when outdoor temperatures begin to fall.

The last thing you want to do is switch on your furnace when winter sets in, only to find that the furnace isn't working properly. Homeowners need to start thinking about preparing their furnaces to perform properly throughout the winter months prior to the onset of colder weather.

Here are three things that you can do while it is still warm outside to ensure that your home's furnace is ready to provide the heated air needed to keep your residence warm and cozy during the upcoming winter.

1. Install a New Filter

One of the most important things that you can do when it comes to keeping your furnace running properly is ensure that there is always a clean filter installed in your heating appliance.

Your furnace sucks in air from the surrounding environment, then heats this air and circulates it throughout your home to create the warm environment you have come to rely on during the cool winter months. Air moving from the environment into your furnace passes through a filter that is designed to remove dirt and debris that could clog up your furnace over time.

If the air filter becomes clogged, your furnace will have to work harder to access the air required to heat your home. This could reduce the efficiency of your home's heating system and cause your furnace to break down prematurely.

Be sure that you swap out your furnace's filter with a new one prior to starting it up for the first time, and keep a supply of filters available so that you can change them out regularly throughout the winter.

2. Remove Obstructions

Another important thing that you can do to get your home's furnace ready for the winter months is clear out any items that are being stored near the furnace. It's common for homeowners to stack boxes, camping equipment and other items near their furnace during the summer, since the furnace room can provide valuable storage space.

While it might be okay to house spare items near your furnace when the appliance isn't in use, these obstructions need to be removed before you start your furnace up for the first time. Any items stored near your furnace could restrict the appliance's access to air, making it difficult for your furnace to efficiently generate the heat needed to keep your home's indoor air temperature comfortable.

Items located near your furnace could also become fire hazards because the heat generated by a furnace could cause nearby objects to ignite. Be sure that you remove all obstructions located near your furnace before winter sets in to ensure the safe and efficient performance of your furnace over time.

3. Invest in An Inspection

Furnaces are complex pieces of equipment that rely on a delicate combustion process to generate heat for your home.

If any of the components within your furnace begin to malfunction, the safety and performance of the furnace could be compromised. It's important that you take the time to have an experienced HVAC technician visit your home and inspect your furnace before firing it up for the winter.

The technician will check to ensure that your furnace isn't emitting deadly carbon monoxide gas, that your furnace hasn't developed any cracks in the combustion chamber, and that the interior surfaces of your furnace are clean so that they don't serve as a fire hazard in the future.

If you take the time to prepare your furnace for winter, you will have access to a functional heating system when outdoor temperatures drop. Contact the experienced HVAC professionals at Parks Davis Air Conditioning & Heating for assistance in getting your furnace ready for the upcoming winter.

How to Know when It's Time to Replace Your Air Conditioner

Wed, 02 Aug 2017 21:18:38 GMT

Deciding whether or not it's time to replace your air conditioner with something newer can be a tough task. After all, your air conditioner is one of the biggest investments you've made in your home thus far. Here are some important factors to consider as you make your decision.

Consider Age

Time can take a toll on just about any appliance. The older your air conditioner gets, the more wear and tear it will accumulate throughout its working life. Age-related problems can make it difficult to keep an older air conditioner working past its prime.

No air conditioner is designed to las forever - even the ones lucky enough to survive for 20 years or more are bound to fail sooner or later. As long as it's well maintained, you can expect the average air conditioner to last for 15 years without encountering any serious issues. Beyond that, you can expect age-related breakdowns that result not only in longer downtimes but also in more money spent on repairs.

It's good practice to consider replacing your air conditioner once it reaches the 10-year mark. This should give you plenty of time to purchase a suitable replacement before your air conditioner reaches its 15-year anniversary.

Consider Performance

If your air conditioner continuously struggles to keep your home cool and comfortable, then it may be time to consider a replacement. Air conditioning units often experience noticeable declines in cooling performance as they age. Even regularly scheduled maintenance or repairs may not be enough to bring a unit back up to its original strength when it was first installed.

Poor performance is also an issue with air conditioners that are incorrectly sized for the task at hand. If your current unit is too big or too small to keep your home comfortable, then it may be time to replace it with one that's appropriately sized for the job.

Also keep in mind that newer air conditioners feature higher SEER ratings , making them more energy efficient than their predecessors. Stepping up from an air conditioner with a SEER rating of 10 to a unit offering a SEER rating of 14 or higher can significantly reduce your energy costs.

Consider Repair Costs

Holding onto an air conditioner for as long as possible may seem like a smart way to get the most out of your investment. But there's also a cost associated with keeping an older air conditioning unit past its prime. A typical air conditioner repair can cost anywhere from a few hundred bucks to several thousand dollars, depending on the type of repair and the amount of labor required.

It's no secret that older air conditioners require repairs more frequently, and these repairs can also be time consuming and costly in terms of labor. Parts that are obsolete or difficult to find can easily result in a more expensive repair. For instance, recharging an air conditioner that relies on R-22 refrigerant could prove prohibitively expensive due to dwindling supplies.

By multiplying the quoted cost of your air conditioner's repair by the age of the unit, you can easily figure out whether or not your current air conditioner is still worth repairing. If the result exceeds the cost of purchasing and installing a brand-new air conditioner, then you're better off buying that new unit.

Consider Upgrades

Today's air conditioners feature a broad range of improvements and advancements that make them quieter and more efficient than older models. These features include electronically commutated motor (ECM) technology, allowing for quieter blower fans with variable speed control. While some of these technologies can be retrofitted on your existing unit, you won't get the maximum benefit you'd receive with a completely brand-new unit.

Don't hesitate to contact the professionals at Parks Davis Air Conditioning & Heating if you think it's time to replace your air conditioning system. We can help you choose and install the unit that best fits your home's cooling needs.

Have Dust Mites? Here’s What You Need to Know

Sun, 04 Jun 2017 21:27:31 GMT

If you or someone in your household suffers from allergies, the culprit may be dust mites. These tiny creatures don't make noise, don't bite, and can't even be seen with the naked eye. However, their impact is significant for millions of Americans who suffer from congestion, sneezing, coughing, and wheezing. Below is more information about this diminutive pest and what you can do to control it.

What Are Dust Mites?

Dust mites are microscopic arthropods, which makes them kin to spiders, ticks, and numerous other eight-legged creatures. However, dust mites are incapable of causing direct harm to humans, as they neither sting nor consume blood from a host.

Instead, dust mites subsist solely on a diet of dead human and animal skin cells that they find inside homes. This environment is ideal for dust mites, and generations will live, reproduce, and die inside human habitations.

Why Do Dust Mites Cause Health Problems?

Dust mites produce strong enzymes within their digestive tract to break down the tough food they eat, and this process is where the problem begins for many people. As dust mites digest their food, they excrete fecal material which contains high concentrations of the enzymes. Unfortunately, the enzymes evoke powerful allergic responses in some people.

One dust mite doesn’t create allergy trouble, but it's not unusual to find homes that contain millions of mites. All of those mites and their fecal matter and decay can add up, causing serious irritation for you and others in your home.

What Can Be Done to Eliminate Dust Mites?

Completely eliminating dust mites from homes is probably impossible, but there are numerous things that can be done to significantly reduce their numbers.

Schedule Professional Duct Cleaning

Air conditioning and heating ducts can become caked with dust and debris, and a significant percentage of this dust is made from dead skin cells. Unfortunately, it is impossible for homeowners to access air conditioning and heating ducts for cleaning.

Instead, you’ll need to contact a qualified heating and air conditioning service company for assistance. A knowledgeable provider will thoroughly clean dirty, dust-filled ducts and remove both mites and their food sources in the process. Once your ducts have been cleaned, you can maintain their condition for a longer period of time by frequently changing air filters.

Lower Humidity Levels Inside Your Home

Dust mites thrive in humid, warm conditions, so reducing moisture inside your home will help dry out and kill them. An easy way to lower humidity levels inside your home is to run your air conditioner more frequently. Alternatively, you can also use a standalone dehumidifier unit to reduce ambient moisture.

Use HEPA Filtration

If you are troubled by dust mites, you may want to supplement your air conditioning and heating with additional air filtration. One popular option is to purchase a HEPA filtration unit; HEPA filters remove extremely tiny particles, even bacteria and viruses, and are capable of cleaning the air of dust mites and their fecal matter.

Remove Unnecessary Fabrics

Another way to reduce the dust mite population inside your home is by eliminating areas where dust mites inhabit and find food. Such areas include carpeting, rugs, drapes, upholstered furniture, and other fabrics.

Replace carpets and rugs with hard floors and get rid of fabric-covered furniture in favor of leather sofas and chairs. Even a child's stuffed animals can be a haven for dust mites, so replace them with toys that are less hospitable to mites.

If you are bothered by allergies and suspect you have a dust mite problem, be sure to contact Parks Davis Air Conditioning and Heating for help. We can clean your air ducts and help improve your home's air quality, thus lessening the impact that dust mites make on your household.
