Common AC Problems

When you’re living in the Fairfax, VA area, you already know how important a role your AC plays in how comfortable your home is. When it’s the middle of a hot summer day, you’re not going to want to find out that your AC isn’t working. But the sooner you know the cause of the problem, the sooner you can get it fixed. These are some common AC problems that you may experience.

Common AC Problems:ac-problems-air-treatment-company

Refrigerant Leaks

Low refrigerant is usually caused by improper charging when your AC is first installed or by a physical leak. If there is a leak, you’ll need to call an HVAC technician to fix the leak, test it, and then charge the system with the right level of refrigerant.

Electric Control Failure

If your AC is turning on and off often, your compressor and fan controls can wear down. This can cause wire and terminal corrosion, so you should contact a professional to look at the electrical connections in your system.

Sensor Problems

If you own a room AC, your unit relies on a thermostat sensor to measure how cool or warm the air coming into the evaporator coil is. If your sensor is moved or faulty, your AC won’t cycle properly and you’re home won’t be cool. Carefully adjust the sensor position so it’s near the evaporator coil but not touching it.

Poor Maintenance

One of the most common AC problems is poor maintenance. If you allow dirtto build up on air filters and coils, your unit won’t have the right air flow and won’t run properly as a result. Make sure to clean your evaporator coils and clean or replace your air filters regularly.

Reasons Your AC Isn’t Cold

It’s the first official day of summer! So the last thing you want to find out is that your AC isn’t cold. More often than not, the reason your AC is blowing warm air is not a complicated issue, but rather something that can be fixed in a few

Reasons Your AC Isn’t Cold

Dirty Air Filter

The filters on your AC prevent dust and other particles from circulating through your home. If you don’t replace or clean them regularly, they’ll become clogged, and your unit won’t have proper air flow. This causes very little or no cold air to be pushed to the evaporator coils and, subsequently, your home.

Faulty Fan Motor

Your AC’s fan pulls cold air from over the evaporator coils and circulates it to your home. If the fan isn’t working properly, the air won’t be pulled from the coils, and they may become too cold or develop frost, restricting your unit’s air flow.  An inspection of the fan will determine if it’s the reason your AC isn’t cold and the potential solution if it is.

Faulty Temperature Control

If your filter or fan motor is not the culprit, you may have a problem with your temperature control or thermostat. Beyond simply checking if your thermostat is set to the right temperature, check your sensing bulb. If it’s defective, it won’t send the power to your compressor, resulting in a lack of cool air flowing through your unit.

If you are experiencing problems with your air conditioner, contact Air Treatment Company. We know how important it is to come home to a comfortable house, so we’re here to help with any AC repairs you need. For more information or to schedule a service, call us at 703-938-0550.


How to Improve Your Water Heater’s Efficiency

 If you could save yourself money around your home, wouldn’t you want to? An easy way to save money is by increasing your water heater’s efficiency since water and energy are usually the two biggest costs on your utility bills each month. And lucky for you, we’re going to tell you a few easy ways you can do just that.

Turn Down Your Thermostatwater-heater's-air-treatment-company

The U.S. Department of Energy recommends having your water heater set to 120°, even though most units come preset at 140°. By turning your unit’s temperature down those 20°, you can save 6-10% in your water heater’s energy consumption.

Keep Up with Maintenance

Water heater maintenance is probably not at the top of your to-do list, but it should start making its way up. Regular maintenance can help detect problems before they become worse and keep your unit running smoothly and efficiently, saving you money in the long run.

Drain Your Tanks of Sediment

Over time, sediment can build up in your water heater’s tank and make it harder for heat to transfer from your unit’s burners to the water inside the tank. Since this makes your unit work harder, drain a few gallons of water from the bottom of your tank a few times each year to keep it running efficiently.

If you need help with your water heater, call Air Treatment Company. Our water heater replacement and repair experts will help you determine the best solution for your home and family. For more information or to schedule a service, call us at 703-938-0550.


Five AC Noises You Should Be Concerned About

These days, air conditioners are made to be pretty quiet and unnoticeable. So you might be surprised to hear some strange sounds coming from yours. ac-noises-air-treatment-companyIf you’re hearing these five AC noises around your home, here’s what they mean and why you should be concerned about them.

1) Banging/Clanging: A banging noise is most likely the result of a loose or broken part inside your unit. It might be a connecting rod or piston shaft, among other things. A clanging noise could be a sign that your unit is failing and you’ll soon need a repair.

2) Clicking: A clicking noise from your AC is a normal part of your unit’s startup and shutdown. But constant clicking could be a sign of a failing thermostat or an electrical problem. Since they can be dangerous, you should keep an eye on any electrical issues.

3) Squealing: Squealing can be caused by a multitude of problems — a bad outdoor blower motor, a malfunctioning blower wheel, etc. Some units squeal upon starting up, which is fine. But, if you notice this is a newly occurring sound, you’ll want to get it checked out.

4) Rattling: Your AC may rattle if it’s starting to break down or if it’s clogged by leaves and twigs. It could also rattle because of an electrical contractor. Since that can cause damage to other parts of the unit, you should have some maintenance done on your AC.

5) Screaming: If your AC sounds like something out of a horror movie, turn it off ASAP since screaming could be a sign of a refrigerant leak or pressure problem. Call an HVAC professional right away to avoid any dangerous situations.

If you notice some strange AC noises, don’t get worries — call Air Treatment Company! We can diagnose the problem with your air conditioner and get it back to good working condition so you and your family can stay cool and comfortable all summer long.

How to Lower Humidity in Your Home

Everyone waits all year for summer to arrive, but once the days start warming up, there’s a serious wish that the temperature wasn’t so high — or at least that it was a dry heat. Humidity can put a real damper on your summer activities, especially when it affects you indoors too. If your home suffers from high moisture, here’s how you can lower those humidity levels.

Take Care of Leaks

Leaks and dripping faucets are not only inconvenient since they waste water, but they also contribute to humidity problems in your home. Get dripping faucets fixed by a plumber and cover sweating pipes with insulation tubes. Additionally, get any leaks or cracks in your roof fixed since those can highly contribute to humidity problems and can cause structural damage.

Invest in Home Upgradeshumidity-air-treatment-company

A few upgrades now can make a big difference in the long run. Add caulk and weatherstripping around windows, doors, and exhaust vents to prevent humid outside air from entering your home. Also, make sure your clothes dryer vents hot air outside and not into any part of the house.

Change Up Your Daily Routine

Aim to take shorter showers in slightly cooler water, and always use your bathroom exhaust fan to get rid of the humid air more quickly. When you’re cooking, keep lids on your pots to hold the moisture inside, and also use your kitchen exhaust fan.

Add a Dehumidifier

A quick and easy way to lower humidity in your home is by adding a dehumidifier to your HVAC system. While there are portable humidifiers available, a whole house humidifier is the best solution for high humidity because they’re more energy efficient and can lower humidity levels on a larger scale.


If you need to lower the humidity levels in your home, contact Air Treatment Company. We can install a whole home dehumidifier in your home to create a more comfortable environment for you and your family. For more information, or to schedule a service, call us at 703-938-0550.

Things to Consider When Getting a Generator

A backup generator is a great resource to have in case the power ever goes out in your home. It can power your fridge to keep food from spoiling and keep the lights on so your children don’t get scared. But how do you know which unit is best for your home? Here are a few things you should consider when getting a generator.

generator-air-treatment-companyThe Power Requirements

You have to ask yourself if you’re going to be powering your entire home or just an emergency space. If you want to power your entire home, you’ll have to account for peak demands, like times during summer months, and the capacity of your electrical services. If you only want to cover emergency areas, you may have to have an electrician split the circuits to a special emergency panel.

The Fuel Type

Most backup generators run on natural gas, diesel, or propane. You’ll want to consider the cost of each type of fuel, as well as its availability in your area. Diesel and propane often require refills during extended power outages, while natural gas is commonly provided by your utility company. However, the type of fuel you can use may be mandated by your town, so be sure check that out.

The Location

You should aim to have your generator in a spot that is easily reached for maintenance as well as high enough for keep rising water from reaching it. Regardless of whether you place your backup generator inside or outside, it will have to meet certain safety requirements. If you place it outdoors, it probably will also need to be covered to meet sound requirements.

What is HVAC Zoning?

hvac-zoningIsn’t it great when you can customize things in your life? You can customize your car color, what food you order, and believe it or not, the temperature in different parts of your home. HVAC zoning is a viable way to heat and cool your home in the most customized way possible. If you’re wondering how it works, we’ve got answers.

Simply put, HVAC zoning breaks your home up into different sections and allows you to control the temperature of each location within your house. You can set different temperatures for different zones, creating an efficient way of heating and cooling your home.

What are the benefits of HVAC Zoning?

  • Energy Bill Savings: Rather than unnecessarily heating or cooling every area of your home at the same temperature, you can have one area, such as your kitchen, at a lower temperature than other areas, such as your bedrooms, and ultimately save yourself money on your energy bill.
  • Better Comfort: A lot of factors can affect how warm or cool your home is, such as cooking areas, sunlight, and windows. Zoning easily helps balance your home’s temperature.
  • Convenience: Zoning involves multiple thermostats, so you won’t have to travel to other rooms in your house to adjust your home’s temperature anymore.

What Goes into Zoning Installation?

How to Keep Pollen Out of Your Home

how to keep pollen out of home

Nothing says spring like warm weather, freshly-bloomed flowers, and… pollen. If you are one of the 60 million Americans who suffer from seasonal allergies, you are already all too familiar with the green stuff.

But did you know pollen can also affect you inside? That’s right; if you aren’t careful, pollen can enter your home and trigger your allergies when you least expect it. Follow these tips from the experts at the Air Treatment Company to keep the pollen out this spring:

  • Stay inside when pollen counts are high. Only go outside if you absolutely have to, and be quick about it. It doesn’t take long for pollen to attach itself to your skin, hair, and clothes.
  • Use the air conditioner. Whether at home or in the car, keep the windows closed and set the air conditioner to recirculate.
  • Keep your car in the garage. If you don’t have a garage, give your car a quick rinse whenever you can. Keep sanitizing wipes in your car so you don’t spread pollen after touching the door handle.
  • Instill a no shoes policy in your home. Shoes can track in pollen, pesticides, and all other types of allergens. Place doormats at all of your entrances, and make guests remove their shoes immediately after entering.
  • Wash your hair before bed. Your hair is a pollen magnet. If you lay down before showering, you will have a pillow and a face full of pollen all night long.
  • Shower immediately after yard work. Think of pollen as a contaminant (which it is). After exposing yourself to a highly-contaminated environment, you will need to decontaminate (shower) as quickly as possible. Don’t even sit down – you will just spread it to your couch.
  • Invest in a High-Efficiency Particulate Air filter. Also known as HEPA, these powerful filters can remove up to 99.97% of airborne contaminants in your home.

Homeowners across Fairfax County, Virginia trust the experts at the Air Treatment Company to keep their air clean and pollen-free. We offer a variety of air purification systems, HEPA filters, germicidal UV lights, and other products designed to improve your household air quality.
