Why is My Air Conditioner Not Turning Off

The Blower Fan is on The Wrong Setting

The most straightforward place to troubleshoot an AC that is constantly running is to check the fan setting many times.

Dirty Evaporator Coil

The evaporator coil inside the indoor air handling unit plays an essential role in your AC’s ability to cool air. If it is clogged with dirt, mold, and other contaminants, it can keep your AC from cooling resulting in prolonged cooling cycles and blowing warm air throughout your home.
