Why Do My HVAC Filters Get Dirty So Fast?

Up to 75% of no-heat calls to HVAC services during the winter are related to a lack of maintenance on any one homeowner’s system. Needless to say, routine maintenance on your HVAC system is one of the best ways to ensure its proper functioning and longevity in your home. However, sometimes even when you provide proper HVAC maintenance from professional HVAC services, your system can still have its problems.

One of the most bothersome challenges for you as a homeowner is when the filter becomes clogged prematurely with hair, dust, and grime. Here are some of the most common reasons why your filter may be prematurely clogging and what you can do to help:

  • Pet fur and dander: A pet’s hair is one of the leading causes of prematurely clogging filters. This is because your pets shed their fur regularly. If their fur ends up on the furniture, on the floors, and in your clothes it’s only to be expected that their fur would end up in the air ducts as well. Be sure that you’re routinely cleaning the house of your pet’s fur and dander to keep it out of the vents and that you’re routinely brushing them.
  • Extreme weather or temperatures: When your thermostat is set to “on” rather than “auto” it makes the fan in the system run constantly. This can increase the amount of debris and dust that is accumulated into your filters.

When the weather is significantly hot or significantly cold, the fan may continuously run even when set to “auto.” Therefore, if your area is experiencing a heat wave for a series of days, it may be a good idea to turn your system off every once in a while to give the fan a break from working.

  • The MERV on your filter is high: When a filter’s Minimum Efficiency Rating Value (MERV) is higher, it means that it traps and holds onto smaller pieces of debris. This can be great because it means that your air is cleaner. But it can also mean a continuous need to clean your filters because that debris can very easily build up. It may also be more taxing on your HVAC fan depending on the energy efficiency of the system. Consult your HVAC contractor for a professional opinion on your system’s filters.

When your HVAC system’s filters are clogged it can often keep the heating or cooling from properly being vented into your home. Be sure to routinely clean your filters in order to ensure the proper functioning of your system.
