5 Reasons Why Your Air Conditioner is Blowing Warm Air

But first, you must understand these 5 reasons why your air conditioner is blowing warm air.

Problem with thermostat

If you have a visible thermostat, try changing the batteries and check it again. Ensure that there’re no loose wires and baseplate connections are securely attached to the wall.

If you recently adjusted the thermostat, give it 5 minutes before checking the unit again.

Outdoor unit not running

You can’t get cool air with the outdoor unit not running. The AC unit has various components including a compressor and condenser fan motor. It’s a sign of a dead unit when you hear a humming sound. Perhaps power isn’t going into the unit because the capacitor is dead. Call a technician immediately to come and fix the issue.

Dirty condenser coil

During the maintenance process, have the condenser coils washed on the air conditioner outdoor unit. Call the technician immediately to lessen chances of issues escalating and becoming costlier.
