Your HVAC air filter works hard to keep dust, dirt, and debris out of your system. How often you need to replace it can depend on the season.
During the summer, when your A/C is running frequently, check your filter monthly and replace it as needed. In the winter, when your A/C gets less use, changing the filter about every three months can help keep your system running properly.
A clean filter is a simple step toward maintaining a comfortable, efficient home.
