Why Is My AC Running But Not Blowing Cold Air?

AC that runs but doesn’t blow cold air usually has one of these issues: low refrigerant, a frozen evaporator coil, thermostat or control problems, or a failed compressor, fan, or blower motor. Electrical faults can also stop cooling. Our Dayton team provides 24/7 diagnostics and repairs for central air and mini-splits, with clear recommendations and durable fixes.

Quick checks:

• Set thermostat to Cool/Auto.
• Replace a dirty filter.
• Check the breaker and outdoor disconnect.
• Look for ice on the indoor coil; if iced, turn system Off/Fan.
