Why Your AC is Blowing Warm Air

If your AC is blowing warm air, and you’re looking for HVAC service near me in Ravenswood, American Home Heating & Air Conditioning wants to help. As a first step in getting your house cool and comfortable, here are a few possible causes of the problem, including some you can handle yourself.

Incorrect thermostat setting

Check your thermostat and make sure it’s not mistakenly set to “Heat.” Also make sure it’s set to “Auto” and not to “On.” With an “On” setting, the fan blows air even when the unit isn’t running.

Restricted airflow

Restricted air flow to and from your AC can limit the cool air coming out of the vents in your home. The source of the problem could be a dirty filter that you need to replace or dirty coils in the outside unit caused by lack of professional maintenance.

No electricity

If warm air is blowing out of your vents, that could be caused by a tripped circuit breaker or blown fuse on the circuit providing power to the outside unit. Check your circuit breaker or fuse panel to make sure the outside unit is getting power.

Other causes

Beyond these basics, other causes could include a problem with the compressor in the outside unit or a low level of refrigerant in your system.
