Haven't Replaced Your AC Filter In A While? Here Are Common Problems You May Experience

Posted on: 29 April 2022

Most homeowners think that the only role of an air conditioning filter is to keep the air coming out of the unit clean. While this may be one of the key functions, it's vital in the effective operation of your unit. When you change your AC filter regularly, you prevent many AC issues and won't have to spend a lot on your energy costs and repairs. Check out a detailed outline of the problems you may experience if you don't consider regular air conditioning filter replacement.

The Evaporator Coils Can Freeze

If there's a heavy buildup of debris on your AC during the hot season, it can cause a restricted flow of air to the evaporator coil. When this happens, the condensation that the AC produces during its operation will freeze. The ice buildup on the coil forces your unit to work harder to remove heat and keep your indoors comfortable. If not addressed on time, your unit may not work effectively.

A Clogged Filter Can Cause Issues With The Blower Fan

The blower fan plays a critical role in pushing air through the filter. So, when the filter is filled with debris, the blower has to work extra harder to pass air through the filter. Such strain doesn't just increase your energy bill but you'll experience inconsistent temperatures around your home. This can also cause the blower fan to burn out, causing your AC system to fail.

Your Unit Keeps Short Cycling

Your AC should only cycle on when it detects a temperature rise and turns off when it rises. If your AC turns on and off frequently, you likely have a clogged air filter. Besides short cycling, you'll notice that some parts of your home will become colder than others. Remember that different things can cause short-cycling, so it's crucial to seek the help of an experienced technician for repairs.

You See A Rise In Energy Bill

For your home to remain comfortable, the AC should circulate consistent temperature around your home. When you have a dirty air filter, you'll have restricted air flowing throughout your house. This means that your AC will work extra harder to ensure the proper airflow around your home. This will cause your unit to pull more energy than usual, resulting in increased energy costs.

Clogged air filters can cause serious problems with your air conditioning unit and expose you to health complications. For effective operation of your unit, it's advisable to change your filter every three to six months.


Summer is Upon Us – Is Your AC Working?

Hi. My name is Laurie Waters. The HVAC contractor was just out at our house last week and did I ever get a lesson from him. You see, we had a warm spell hit and I went to turn our air conditioning on for the first time since last summer. Much to my dismay, it wasn’t working. All I got was a blast of warm air. The fan was bringing the outdoor heat inside. Thank goodness it wasn’t anything major. My unit needed Freon. While he was here, the contractor taught me how to do some routine maintenance around my unit, vents, and filters. I’m going to share this information with you. I hope you find it to be useful.
