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%.
