Replacing Your HVAC Filter: What You Need to Know

Your home’s HVAC filter is a vitally important part of your overall heating and cooling system. It aids in reducing your home’s allergens such as dust, lint, dust mites, mold spores, pollen, pet dander, and smog.

Replacing your HVAC filter can lower your unit’s energy consumption by up to 15 percent, according to a U.S. Department of Energy report. 

Dirty air filters can also damage your HVAC system by restricting airflow into the air handler. This restricted airflow puts a strain on the handler’s fan motor which. Left unchecked, the motor will burn out and the system will overheat and fail. Dirty HVAC coils make the system work harder and are more prone to freezing over or burning out. They can also lead to costly HVAC cleaning expenses.
