Your HVAC filter captures tiny particles as small as 0.3 microns in size. This includes pollen, pet dander, bacteria and dust. Regular changes of your HVAC filter ensure that your heating and cooling system can operate as efficiently as possible. Changing the filter is easy to do yourself, or you can have our experienced technicians change it during your next tune-up. Here are three signs it’s time to change your air filter in Auburn, AL.

Low Airflow

According to the Department of Energy, a top sign that you need to chair the HVAC filter is low airflow from the vents. The obstructed filters do not allow enough air to pass through, so the output through your vents is lower. Changing the dirty air filter and replacing it with a clean one should restore proper airflow through your vents. If the airflow is still lower than you think it should be, consider duct cleaning or other indoor air quality services to remove any extra dust.

Frequent HVAC Cycling

Low airflow through the filter means less cooled or heated air reaches your living spaces. The thermostat won’t register the work done by your heating and cooling system, causing the system to cycle longer and more frequently. This can result in extra wear and tear on your HVAC system. A dirty air filter could also increase your heating and cooling costs by as much as 15 percent.

Increase in Dust

Once the air filter’s pores are filled with debris, they can’t hold any more dust or dirt. The rest of the dust or dirt will blow through your ducts and into your home. You might notice that the flat surfaces in your home are dustier than usual. Allergy and asthma symptoms could worsen.
