Do you know how to change your A/C or furnace air filter?

Changing out your AC/furnace filter(s) is essential to providing a healthy indoor environment for you, your family, friends, pets, and other occupants. Not only will replacing your air filter help prevent harmful airborne contaminants from recirculating, but it can also help reduce hefty electricity and air conditioning maintenance costs.

How to Change your AC/Furnace Filter(s) - A Step-by-Step Guide:

  1. Make sure you have the correct size replacement filter.
    • Not sure? Most air filters have the size printed on the outside of the frame, so check to see what size filter is currently in your air return.
    • Can’t find the size? Here is a step-by-step guide on how to measure your filter. https://www.airfilterusa.com/resource-center/blog/how-to-measure-air-filters/
  2. Turn your air conditioning unit completely off. This helps prevent any loose dirt and debris from being sucked back into the a/c unit, which can cause potential equipment damage and cause contaminates to recirculate.
    • Can’t find the on/off switch on the thermostat? Locate your breaker box and switch off power from there.
  3. Open you air return grill, remove your old filter and dispose of it. We recommend placing the old filter in an empty trash bag to help contain contaminants.
  4. Insert new filter. Make sure that arrow points away from the return and toward the air handler.
  5. Close air return grill and lock back into place.
  6. Sit back, relax, and breathe in quality air and enjoy lower electricity costs.
