How to Change Your HVAC Filter?

Every HVAC system includes an air filter. The goal of the filter is to keep your home clean by filtering dirt and particles from the air that travels through while keeping your heating and cooling Mesa, AZ, running efficiently.

Simple Steps to Successfully Change your HVAC Filter

Locate Your Air Filters3

  • The return air register 

Examine your Filter Size

Examine MERV Rating

Examine MERV (Minimum Efficiency Reporting Value) rating on your air filter. On a scale of 1 to 16, the MERV rating shows you how effective your air filter is at its work. 

Check your owner’s manual to find what MERV rating your air conditioner can tolerate. If you can’t find it, you may always hire an HVAC specialist to evaluate and recommend your equipment. 

Turn off the HVAC System

Remember to turn off the HVAC unit before proceeding with the replacement procedure. While replacing the filter, this step will help prevent dust and other debris from entering and accumulating inside the HVAC system. It also decreases the possibility of contaminated air moving into your home.

Remove the Old Air Filter

When you have identified and purchased the appropriate replacement filter, you are ready to replace the old one. Remove the old filter with care and dispose of it properly.

Check that there are no gaps around the edge of the air filter frame. If this is the case, you may be using the incorrect size filter, or the filter may be malfunctioning or damaged. Contact the technician of Gilbert AZ air conditioner repair for help.
