How Often Should You Change Your HVAC Filter?

You may need to change your filter more often than you realize!

Air filters are a crucial component of your HVAC system that most people ignore. However, air filters not only keep your air clean, but they also improve the efficiency of your system! Air filters protect the inner workings, delicate fins, and coils of their HVAC system by stopping debris from piling upon them. Conversely, filthy filters make it easier for dust and dirt to pass through and eventually settle on your system. The best way to avoid this and maintain a new system is to replace your air filter regularly. To know when your filters need to be changed, though, you need to consider several factors.

How Do Air Filters Work?

Made from many materials, the primary purpose of air filters is always the same. Air filters prevent dirt, dust, pollen, and other debris from entering your HVAC system. Depending on your system and filter’s rating, your filter may even capture bacteria and viruses. Make sure to check your unit’s requirements when choosing new filters to ensure they are adequate material and have sufficient filtering capacity.

How Often Should You Replace Your Filters?

The air filter should be replaced at least once every six months, but most filters will need to be replaced much sooner. The regularity with which you should replace your air filter depends on several factors, including:

  • How often do you use your HVAC system
  • Whether or not you have pets
  • The air quality in your neighborhood
  • The size of your home
  • Allergies in your home

If you have a fiberglass filter, then you may need to replace it as often as every month. On the other hand, air filters made from higher quality materials usually last longer.

Efficient Systems Use Clean Filters

A dirty air filter forces your HVAC system to work much harder than it should to move air around. Dirty filters also tend to release some of the debris they have picked up if they are left in your system for longer than they should be. However, certain HEPA filters may also cause your HVAC system to work harder even while clean. This is because HEPA filters provide superior filtration at the cost of making it harder for air to move through them. When choosing a replacement air filter, make sure you select a level of filtration that is right for your home and budget.

Have A Professional Replace Your Filters

The easiest way to replace your air filter will be to have a professional do it for you. Most HVAC companies will clean or replace your air filter as a regular part of their HVAC maintenance services. They will know what filter is best for your system and when its next cleaning or replacement should occur. You may not need a full maintenance service performed on your HVAC every single month. Still, an occasional check-in with a local HVAC company like Santa Fe Express Plumbing and Drain will set you up for continued performance from your HVAC system.
