Changing your filter is a rather inexpensive way to keep your HVAC system working properly and to lower your electric bill. Have you ever received your electric bill and felt a sense of sticker shock? Believe it or not, you can lower your electric bill just by changing out a dirty filter to a clean one. How is that possible? When your filter is full of dirt and debris, your HVAC unit has to work harder to get your desired temperature which means it will use more electricity. Also, the harder your unit has to run, the more probable it becomes for your unit to malfunction. Finally, a clean filter improves the air quality in your home.
How often should you change your filter? Every time you receive your electric bill, check your filter. If it’s dirty, change it. Smaller houses may only need to change their filters every 2-3 months while larger homes may need to change them once a month.
