Double-check that your thermostat is set to the cooling mode with the fan on “Auto” and that the desired temperature is lower than the room temperature. If the thermostat seems to be working, be sure none of the return vents are blocked and that the air filter is relatively clean. Check the evaporator and refrigerant lines for signs of frost or ice, and make sure the area around the condenser coil is free of debris like tall grass, tarps, toys, or furniture. If the system is still running poorly, call our team at Mountain Air for same-day AC repairs anywhere in the South Ogden area.
