Your HVAC System Air Filter

If you’re wondering why your HVAC system isn’t functioning properly, you may want to check your air filter. It’s one of the biggest causes of system failure and should be something you check and change on a regular schedule.

How Air Filters Work

Air filters are inserted in HVAC systems to act as a barrier, preventing contaminants and other particles from circulating in the air or from reaching parts of your system and causing damage. They work to block dust, pollen, lint, mold, hair, animal fur, bacteria and more.

Most manufacturers recommend basic filters are changed every 30 to 60 days. However, that schedule can vary. For instance…

  • If your home is pet-free, you can likely use a filter for up to 90 days.
  • With a single pet, changing your filter after 60 days is ideal.
  • Multiple pets can warrant a filter change between 20-45 days. This is also the case if anyone in the home suffers from allergies.
  • Vacation homes with no pets can go longer usually, with filters lasting six to 12 months.

 

Consequences of Not Changing your Filter

Not changing your filter regularly can result in it becoming clogged by build-up. That build-up reduces the efficiency of your system, making it hard for airflow to be regulated and for the unit to heat or cool properly. The contaminants it is supposed to help protect you and the unit from can damage the system and get back into the air, allowing occupants to breathe it in, bringing on headaches, itchy eyes and even dizziness. Long-term, this can also increase the risk of respiratory disease, heart disease and cancer.

Your system might even experience failure. Replacing it could cost anywhere fro $4,000 to $12,000. Keep in mind that air filters usually cost less than $40.

 

Now What?

Check those filters. Figure out which need to be replaced and do it as soon as possible. If your old filter looks like nothing could pass through it, call on an experienced HVAC technician so your system can receive a full inspection and any related issues can be resolved.
