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

Intermittent warm air usually means airflow, thermostat, or low refrigerant. Do a few quick checks, then schedule service if it persists. We provide AC repair in Watertown and Newton. Our $99 AC Tune-Up includes a comprehensive 21-point inspection, refrigerant level check, and coil cleaning.

• Set thermostat to Cool and Auto.
• Replace a dirty air filter.
• Check the breaker and outdoor unit is running.
• Look for ice on coils; turn system off to thaw.
