Why is my LG Air Conditioner not cooling or heating effectively?

  Your LG Air Conditioner may not be cooling or heating effectively because the air filter is dirty. You can find air filter cleaning instructions to resolve this. Also, the room might have been very hot when the air conditioner was first turned on; allow time for it to cool down. Check if the temperature has been set incorrectly or if the indoor unit's air inlet or outlet vents are obstructed.

  Melvin KaiserAug 13, 2025
  If you hear a noise that sounds like water flowing, it is the sound of freon flowing inside the air conditioner unit. If you hear a noise that sounds like compressed air releasing, it is the sound of the dehumidifying water being processed inside the air conditioning unit.
