  Several factors could affect the cooling or heating performance of your LG Air Conditioner. First, check if the air filter is dirty and clean it according to the instructions. If the room was very hot when you first turned on the unit, allow some time for it to cool down. Also, make sure the temperature is set correctly. Finally, ensure that the air inlet or outlet vents of the indoor unit are not blocked.

  The noise from your LG Air Conditioner could be due to a couple of reasons. If you hear a sound like water flowing, that's just the sound of freon moving inside the unit. If you hear a sound like compressed air being released, that's the dehumidifying water being processed inside the unit.
