You depend on the HVAC system to keep you comfortable throughout the year, but to keep the system operating properly, you need to do your part as well. As the team at Comfort Tech Heating and Air Conditioning in Thomasville, NC, notes, few maintenance tasks are more important for this goal than regularly changing the air filters. Here’s a closer look at what you need to know about this essential task.

Why Should You Change the Air Filters?

The air filters prevent dust and other pollutants from getting distributed through the air ducts. The air coming that returns to the HVAC system will pass through the filter before getting redistributed throughout the house. Over time, however, a buildup of dust and debris will force your system to work harder to heat or cool the house.

To maintain good indoor air quality and keep the HVAC system from getting overworked, it’s generally recommended that you change your air filters every 90 days. For homes with pets or individuals with allergies, an air filter change should be performed after 30 to 60 days.

How Do You Change the Air Filters?

Fortunately, replacing the HVAC system’s air filter isn’t too complicated. You’ll change the filter at the return air intake—a large vent located within the home. 

To replace the filter, release the clips to open the door. You’ll see the old filter resting inside the frame. Pull it out, and slide the new filter in place with the “air flow” arrows pointed to the inside of the vent. Close the return air intake valve, and you’re done.
