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

Intermittent warm air usually points to airflow, thermostat, or a component issue. Make quick checks first, then schedule a diagnostic so a technician can test and repair parts like capacitors, blower motors, or address refrigerant-related problems.

Quick checks:

• Set thermostat to Cool and Auto; lower setpoint 3–5 degrees.
• Replace a dirty filter; open all supply/return vents.
• Clear debris from the outdoor unit; ensure its fan runs.
• If you see ice on lines or coil, turn system off and set fan to On.
