Why is My Ac Stuck on Defrost

There are a few reasons why your AC could be stuck on defrost. One reason could be that the thermostat is set to the “defrost” position. Another reason could be that there is something blocking the air flow, such as a dirty filter or a closed damper.

Lastly, it could be an issue with the AC unit itself, such as a frozen evaporator coil. If you’re not sure what’s causing the problem, it’s best to call a qualified AC technician for help.
