What should I do if my AC is blowing warm air intermittently?

Intermittent warm air usually means a thermostat/controls issue, low refrigerant, frozen coils, or an electrical fault. These are common AC problems we diagnose and repair 24/7 in Dayton, OH. Try simple checks first, then schedule service if it persists.

Quick checks:

• Set thermostat to Cool and Fan Auto.
• Replace the air filter.
• Remove dirt and debris from the exterior unit.
• If airflow is weak or air warms mid‑cycle, service may be needed for refrigerant, coils, blower, or wiring.
