Hot air is not what you want to feel coming out of your vents in the middle of summer. There are a number of reasons why your air conditioning unit could be malfunctioning, so before you panic, the team at Osterwisch Company in Cincinnati, OH, suggests identifying the cause of the problem first. This will let you know whether it’s time to call in a professional technician.

3 Possible Causes for an AC Unit Blowing Hot Air

1. The Wrong Thermostat Setting

Check the thermostat to ensure it’s on the correct setting. Switching on the heat by accident is a common cause of warm air blowing from the AC unit. If the outside air conditioning unit is off, but your thermostat is switched to “on”, this fan within the indoor unit will continue to blow warm air.

2. A Dirty Air Filter

3. A Refrigerant Leak

Refrigerant leaks can be caused by a loose component, poor assembly, or a worn service valve. In addition to the AC unit blowing warm air, other signs of a leak may include gurgling noises and ice on the refrigerant line. If you notice these signs, call a professional in to address the problem since it’s dangerous to handle it on your own.
