Why Your HVAC Filter Keeps Clogging

Does it seem like every time you check your HVAC filter, it needs to be replaced? While many filters need to be swapped out every 1-2 months, if you find your HVAC filter is clogged after just a few weeks, you may have a problem. A dirty filter impacts your energy efficiency, but you should not need to replace your filters more than once per month. Here are some reasons your filters may be clogging prematurely and how to fix the problem.

Pets, Dust and People

How much debris is floating in your air can impact your air filters. Pet hair and dander contribute to filter clogging, as does the amount of people and dust in your home. Vacuum and dust your home regularly to cut down on filter changes.

Is Your Fan On?

The fan on your HVAC system has an “on” and “auto” setting. If you leave it “on” the fan will be going 24/7, pulling air through the filter. Set it to “auto” to turn the fan on only when heating or cooling, which will extend the life of your filters.

HEPA Filters and High MERV Ratings

Filters that are designed to clean minute particles out of the air may purify the air, but they also clog quicker. HEPA filters and those with high MERV ratings can collect more dirt, but they can also put stress on your HVAC system. Changing filters to a lower MERV rating can make your filters last longer and minimize workload on your HVAC system.

If you follow these tips and still have problems with your filters clogging, call your local HVAC service company. You may have leaks in your ductwork or other issues that are causing dirty filters.
