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

If your AC blows warm air on and off, check simple causes first. Ensure the thermostat is set to Cool and the fan is on Auto. Replace a dirty filter. Confirm the outdoor unit has 2–3 ft of clearance and the breaker isn’t tripped. If you see ice on the refrigerant lines or smell musty odors, turn it off and schedule service. We offer 24/7 emergency AC repair and a $179 diagnostic, waived with any approved repair. We serve Garden City and Nassau County.
