Changing your heating and cooling system's air filter on a regular basis keeps air flowing without overworking equipment. You'll also keep out dust and dirt that can lead to expensive repairs or early system failure.

Skill Level: Basic
Simply check your filter every 30 days, especially during heavy-use months like deep winter and the hottest months of summer. If the air filter looks dirty, replace disposable filters or clean permanent filters at least every 90 days.
Cost Range: $6-$35
Changing your air filter is an inexpensive, do-it-yourself way to keep your heating system running efficiently and lasting longer.
Savings: Up to 15% in energy consumption
Dirt and neglect can cost you in wasted energy and potentially expensive equipment repairs. Filters are a relatively low-cost way to avoid both! Clean filters can actually lower your energy consumption by up to 15%.
