Understanding How Often to Change HVAC Filters

Air Conditioning FiltersTo properly maintain the efficiency and condition of the heating, ventilation and air conditioning, or HVAC, system in your home, it is important to replace the air filters on a regular basis. These filters remove allergens and debris to freshen the air in your home and keep the heating and cooling system components in excellent condition. The filter replacement interval you should follow depends on the filter type, your household size, and other important factors. Utilize this guide to learn just how often to change HVAC filters to maintain the efficiency and condition of your heating and air conditioning system.

Types of HVAC Air Filters

The type of filters you have in your HVAC system will greatly influence the ideal replacement interval to follow. The filters available for residential heating and air conditioning equipment including:

  • Pleated
  • Washable
  • HEPA
  • Fiberglass

The washable filters will last up to five years with cleanings performed on a quarterly basis. All of the other filters require regular replacement intervals to continue to remove dust and other particles from the air in your home.

Ideal HVAC Filter Replacement Intervals

Under normal use, pleated and fiberglass filters are designed to only last about three months before requiring replacement with a brand-new filter element. High-quality HEPA air filters last much longer with a regular service life of six months or less.

The size and makeup of your household have a big influence on the service life of your HVAC air filters. If you have pets, for example, you will need to change your heating and cooling filters on a monthly, rather than quarterly, basis. People with allergies may benefit from more frequent air filter replacement intervals to control the flow of allergens through the home.

If you delay replacement, the small particles picked up by the filter may block airflow and reduce the efficiency of your heating and cooling equipment. Over time, the reduced efficiency can cause damage to the internal HVAC components, necessitating parts repair or replacement services. Therefore, you should follow a regular air filter replacement schedule to keep your HVAC equipment working great year after year.
