Why Is My AC Running But Not Blowing Cold Air?

Your AC can run but not blow cold air if airflow is restricted, the thermostat is set wrong, refrigerant is low, the coil is frozen, or the outdoor unit is blocked. In Roanoke and Salem, our NATE-certified techs can diagnose and repair the issue, including 24-hour emergency service, 365 days a year.

Quick checks:

• Set thermostat to Cool and auto fan.
• Replace a dirty air filter.
• Clear 2–3 ft around the outdoor unit.
• Check the breaker and condensate drain.
• If you see ice on lines, turn system off and call.
