How Often Should I Replace My HVAC Filter?

Your HVAC air filters need to be replaced every one to three months, depending on how often you’re running your heating and cooling systems. The two main reasons why you need to replace your filters regularly are:

1. Improved indoor air quality – Your HVAC filters trap the airborne particles in your air—such as dust, mold spores, allergens, bacteria, and more—and keep them from being circulated in your home. However, if you have a dirty, clogged filter, it can’t catch those harmful particles which can lead to reduced indoor air quality.
2. Improved heating and cooling system performance – One of the main benefits of having clean HVAC filters is the improved performance for your heating and cooling systems. If the filters are clogged and dirty, they restrict the airflow in your system, thus making it more difficult to circulate the air in your home and requiring your systems to work harder.

Many people ask us why they can’t just clean out their HVAC air filters, and the answer is simple: the majority of reputable HVAC experts will agree that washable, reusable air filters can be dangerous for your home. If they are not cleaned and dried properly, it can lead to mold growth—the last thing you want when it comes to filtering the air in your home.
