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

Intermittent warm air usually points to refrigerant, airflow, frozen-coil, or thermostat/electrical issues. Try a few quick checks, then schedule service if it continues. Green Air Care offers same-day and 24/7 emergency AC repair in Glenview and nearby areas.

• Set thermostat to Cool and lower the setpoint.
• Replace or clean the air filter.
• Clear debris around the outdoor unit and confirm the fan spins.
• Check the breaker and furnace/air handler switch.
• Look for ice on lines/coils; if present, turn AC Off and Fan On to thaw.
