      Carolyn JohnsonAug 21, 2025
      The noise from your LG Air Conditioner could be due to a couple of reasons: If it sounds like water flowing, this is the sound of freon flowing inside the unit. Alternatively, if it sounds like compressed air releasing into the atmosphere, this is the sound of the dehumidifying water being processed inside the unit.
