What Happens If You Don’t Change Your Air Filter

General Information

Do you know what happens if you don’t change your air filter regularly? Unfortunately, most people don’t think about their HVAC systems until they stop working. One of the biggest reasons for a system failure is (you guessed it) clogged air filters.

Read more below to find out what happens when you don’t change your filters on a regular basis.


What is the primary function of air filters?


Filters are designed to block indoor contaminants and pollutants like:

  • Dust
  • Pollen
  • Lint
  • Mold
  • Hair
  • Animal fur
  • Bacteria

Filters act as a main barrier to prevent these and other particles from circulating in the air.

How often should air filters be changed?

The general rule of thumb is every 30 days. If you don’t have any pets, or you are rarely at home, you may be able to wait 60 days, the main thing to remember is they need to be changed at least 4 times a year. You can also take a sharpie and note the date on the filter, and then schedule a phone reminder to assure you don’t forget.

What happens when you don’t change the filter?

Particles and contaminants start to clog the filter and ultimately causes issues with your HVAC system. When you have a dirty filter, air can’t flow through it any longer like it was designed to. This can lead to higher energy bills, health concerns and major problems with your system.
