What to do if your AC is blowing hot air?

Troubleshooting the Thermostat

Sometimes, the problem could be something as minor as having the thermostat set wrong. Always be sure to double-check that the system is set to cool and that the fan is set on auto as opposed to on. If you’re lucky, this little change could potentially be the answer to your problem.

Dirty Working Conditions

If you’ve already checked your thermostat, it may be time to clean. A dirty condenser unit or a dirty air filter could be the culprit. The AC needs a clear path to be able to deliver cool, refreshing air. If dirt or debris is blocking the way, the cool air is being stopped in its tracks.

Electrical Issues

A loss of power to the outside unit could create problems within the vent. Checking the circuit breaker and emergency shutoff switch is the best thing to do here. However, be mindful that if you are consistently checking the circuit breaker, you may have a serious electrical problem. If that is the case, reach out to a professional as soon as possible!

Low or Leaking Refrigerant

Low refrigerant is a fairly common reason for AC units to blow warm air, but it is one that cannot be solved with DIY fixes. Professional help is surely needed to figure out and solve this problem. If the refrigerant is not leaking, then maybe the air ducts are. Chances are your ducts are hidden in your walls, attic, or basement, and for that reason, professional help will be necessary to get to the bottom of the problem.
