A Common Misconception in Home Comfort
One of the most persistent myths in the HVAC industry is that every homeowner needs to change their air filter monthly, no exception. At Refrigeration & Electrical Service, we’re here to set the record straight about this oversimplified recommendation.
Why This Myth Exists
The monthly replacement guideline became popular because it’s easy to remember and seems like a safe recommendation. However, filter replacement frequency actually depends on several factors:
- Household size
- Number of pets
- Local air quality
- System usage
- Filter quality and thickness
The Reality of Filter Replacement
Here’s what actually determines your filter replacement schedule:
1. Basic 1-inch filters in homes with pets may indeed need monthly replacement
2. High-quality pleated filters can last 3-6 months
3. Homes without pets or allergies might go 2-3 months between changes
4. Vacation homes with minimal use may only need quarterly changes
The Right Approach
Instead of blindly following a calendar-based schedule, we recommend checking your filter monthly by holding it up to the light. If you can’t see light passing through, it’s time for a replacement. This practical approach saves money while ensuring your system runs efficiently.
Remember, proper filter maintenance is just one aspect of keeping your HVAC system running efficiently. Regular professional maintenance remains crucial for optimal performance and longevity of your heating and cooling equipment.
