Do I Really Need to Change My HVAC Filters?

One of the easiest things you can do to maintain your HVAC unit and your home’s indoor air quality is to make sure that you’re regularly changing out the air filters. How often you change them depends on several factors that we’ll discuss throughout this blog post.

How Often Should I Change My Air Filters?

As a rule of thumb, your air filters should be changed every six months. However, if you live in a home with pets, you should change your filters every two to three months. This will keep the pet dander from recirculating throughout your house.

Additionally, if you have babies or young children living in your home, you should change out your filters every one to three months. Young children have weaker immune systems and are more susceptible to airborne illnesses, making clean filters necessary for their health.

What Affects the Lifespan of Your Air Filters?

There are a number of factors that will shorten the lifespan of your HVAC system, including but not limited to, the following:

  • How often you use your HVAC system. The more often you use your HVAC system, the more air is filtered through your air filters. This wear and tear will require you to change the filters out more frequently.

  • The size of your house. If your home is on the smaller side, then your HVAC system won’t need to pump as much air in order to achieve a temperature change, which could mean fewer temperature changes.

  • The air quality within your home. Your indoor air quality is affected by many factors, including the quality of the outdoor air, whether people smoke, how often you clean, among other things.
