Changing your HVAC air filter is one of the easiest and most effective ways to maintain your home’s comfort and efficiency. A clean filter improves indoor air quality, helps your system run smoothly, and can even lower your energy bills. On the other hand, a clogged filter restricts airflow, forces your system to work harder, and can lead to costly repairs down the line.
How Often Should You Change Your Filter?
The frequency depends on the type of filter you have:
- 1-inch filters should be replaced every 30 days to 3 months.
- 4-inch filters last longer and can be changed every 90 days to 6 months, depending on the manufacturer’s recommendations.
Filters don’t just improve air quality—they also protect your HVAC system from dust, pet dander, and debris buildup. If neglected, these particles build up, reducing efficiency and even shortening the lifespan of your system.
Stay on Top of Maintenance
To keep things running smoothly, set a schedule to replace your air filter regularly. But don’t just rely on a calendar—check the filter every month. If it looks dirty, swap it out!
If you’ve been diligent about changing your filter but still notice your home isn’t as comfortable as it should be, your energy bills are creeping up, or your system is running more often than usual, it may be time for a professional inspection.
