How Often Should I Change My HVAC Air Filter?

Changing HVAC Air Filter

It is recommended to change your HVAC air filter every 90 days if your home has no pets. If you do have pets, it is suggested to change the HVAC air filter every 60 days. However, if your home is a vacation or single-occupant home, every 6 to 12 months is fine.

Think about your home and everything that happens inside of it every day. Your kids come home from school and gather around the kitchen table for a snack before starting homework. Your dog stretches lazily on the couch before snoozing the afternoon way. You curl up in the recliner to catch up on your favorite TV show before bed. No matter what your lifestyle entails, your home is your favorite place to be.

To keep your home the oasis that you love, you have to maintain the “behind-the-scenes” part of it too. That includes your HVAC air filter. Your HVAC air filter plays a huge role in maintaining the quality of your home’s air. Your home’s air filter removes contaminants and particulates from the air which is why it is so important to regularly change it.

“Your air filter is really your home’s undercover superhero,” says Jacob Sandlin, HVAC-Operations Manager at Charlotte Mechanical. “It extends the life of your HVAC unit, it keeps energy costs down, it maintains healthy air quality and it keeps your HVAC system clean.”

So, just remember, if your home is allergy and pet free, changing your HVAC air filter every 90 days is recommended. If you do have allergies or furry friends, bump that change time up to every 60 days. Lastly, if your home is a vacation or single-occupant home, every 6 to 12 months works great.

  • Once you have the correct air filters, you’re ready for the installation!
  • Open the door on your return air intake and remove the old filter.

“Jeff Crane and his crew with Charlotte Mechanical recently replaced our old heat pump with a new Amana system.  Everyone on this project was extremely professional and the quality of their installation was most excellent.  Even the county inspector made a comment on the “very nice job” that Jeff and his crew had performed.  I highly recommend Charlotte Mechanical.”
