How To Reset A Home AC Unit

Resetting your home's air conditioning unit is a common troubleshooting procedure used to "reboot" the system much as you would a computer with strange symptoms. Accomplish this by cycling the power to the air conditioning unit, a procedure which generally takes around 10 minutes or less.

Step 1

Locate the shutoff panel on the house wall next to the outdoor compressor unit. Turn the unit to the "Off" position.

Step 2

Locate the 240 volt circuit at the main electrical panel of your home. Turn it to the "Off" position.

Step 3

Wait five minutes or more and turn both back on, restoring the power to the unit and resetting it.
