Air Authority Answers: How Often Should I Change My HVAC Filters?

With all the responsibilities that come with homeownership, changing your HVAC filters probably isn’t at the top of your mind. But when you or your child has constant sneezing attacks from allergies or your HVAC seems to be working harder to heat or cool your home, it’s time to assess your filters and decide when to change them out. 

In today’s blog post, Air Authority answers the question: How often do I need to change my HVAC filters?

Why You Should Change Your HVAC Filters Regularly

HVAC filters exist in your air duct openings and capture dirt, dust, debris, pet hair, allergens, and bacteria that attempt to pass through as air circulates. When replaced often, they help increase the air quality in your home.

If you or anyone in your home suffers from asthma or allergies, changing out your HVAC filters can help reduce your symptoms by preventing pollen, spores, and other allergens from circulating in your air.

 If you leave the same filter in for too long, this can cause severe build-up in your ductwork and cause health problems. Changing your filters regularly can prevent having to pay for expensive duct cleaning. 

Dirty HVAC filters will also cause your filter to become clogged–making it harder for air to move through and decreasing the efficiency of your HVAC system.

When Should You Change Your HVAC Filters?

Determining when to change your HVAC filters will depend on several factors:

• Type of filters
• Size of your home
• HVAC Frequency of use
• Pets in the home
• Allergies in your family 

There are two common types of HVAC filters: disposable fiberglass filters and pleated filters. Fiberglass filters are the least expensive option and do a fine job of filtering out larger particles. However, they need to be changed more often–ideally every 30 days. 

Pleated filters consist of higher quality material but still need to be changed every 3-6 months. 

The size of your home and how often you turn on your HVAC system are also factors. Smaller homes circulate less air, so the filters may last longer. HVAC filters will also last longer for homeowners who live in temperate climates and don’t turn on their HVAC very often. 

If you have pets who shed or allergy sufferers living in your home, it’s best to change your filters more often to prevent build-up and reduce your symptoms.
