How to Check and Change Your Furnace Filter

Proper maintenance of your furnace filter can help optimize airflow from your furnace, which will keep it running efficiently and economically during the coldest months of the year.

To prevent burnout of your furnace parts, we recommend inspecting your filter monthly and changing it every three to six months. Here’s how it’s done:

  • Begin by carefully opening the furnace’s external rack or panel door.
  • Remove the furnace filter by sliding it out. Take a look at the filter to see if there’s any darkness or discoloration.
  • If you can’t see through the filter, it’s definitely time for a new one. Slide the new filter into the furnace, making sure that it is installed in the direction of the airflow. And that’s it – you’re done!
