How important and often should you change your A/C filters?
General Recommendations:
1. Fiberglass Filters: These basic filters typically need to be replaced every 30 days due to their lower quality and shorter lifespan.
2.Pleated Filters: A step up in quality, pleated filters can last up to 90 days before needing replacement.
Factors Influencing Replacement Frequency
1. Household Pets: If you have pets, you may need to change your filters more frequently, possibly every 2 months, as pet hair and dander can clog filters quickly.
2. Air Quality: Poor indoor air quality, such as smoking indoors or high dust levels, can lead to faster clogging of filters. In such cases, checking the filter monthly is advisable.
3. Seasonal Changes: During peak usage seasons (like summer and winter), filters may need to be changed more often due to increased system operation.
* Regularly changing your AC filters is crucial for maintaining good air quality and ensuring your HVAC system operates efficiently. A clogged filter can lead to increased energy consumption and may shorten the lifespan of your HVAC equipment.
* Poor indoor air quality can lead to serious health issues, including respiratory problems, allergies, and chronic diseases.
