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

Start by checking basics. Set the thermostat to COOL and lower than room temp. Replace a dirty filter and open all vents. Check the AC breaker. If you see ice on the refrigerant line or coil, switch the system off and run the fan to thaw. If issues persist, it may be a refrigerant leak, frozen coil, blower motor, or thermostat fault. We provide detailed diagnostics and 24/7 AC repair in Ellicott City and Columbia.
