How Often to Change Your Air Filter - Parkersburg, Clarksburg & Surrounding Areas
Generally, you should change your air filter at least every 90 days for better indoor air quality and HVAC system health. Factors like cigarette smoke, pet hair or excessive dust can shorten the time between changes. Check up on your filter once a month, and if it looks clogged or dirty, swap it out with a new one.
When you change the filter, remember to aim the arrows toward your HVAC unit.
