Why Perfect Aire Air Conditioner cooling but room is too warm?
- VVictoria NielsenAug 1, 2025
If your Perfect Aire Air Conditioner is cooling, but the room is too warm and ice is forming on the cooling coil, set the unit to FAN only mode to defrost the coil. This issue may arise if the outdoor temperature is below 64ºF (18ºC), the air filter is dirty (clean it), or the thermostat is set too low for nighttime cooling (adjust the temperature to a higher setting).
