  Several factors can affect the cooling or heating performance of your LG Air Conditioner. The air filter might be dirty, so please refer to the air filter cleaning instructions. If the room was very hot when you first turned on the unit, allow time for it to cool down. Also, verify that the temperature has been set correctly and ensure that the air inlet or outlet vents of the indoor unit are not obstructed.
