A » There are several reasons your HVAC might be blowing warm air, such as a thermostat set incorrectly, a refrigerant leak, or a dirty air filter. Ensure your thermostat is set to "cool" and at the desired temperature. If issues persist, check for blockages in the air filter or consult a professional to inspect for refrigerant leaks or other maintenance needs to restore optimal performance.
