      Dr. Kyle RodriguezAug 26, 2025
      If your LG Air Conditioner is operating noisily and you hear a sound like water flowing, this is the normal sound of freon flowing inside the unit. If you hear a noise that sounds like compressed air releasing, this is the sound of dehumidifying water being processed inside the unit.

      The noise from your LG Air Conditioner could be due to a couple of reasons: If it sounds like water flowing, that's just the refrigerant moving inside the unit. If it sounds like compressed air releasing, that's the dehumidifying water being processed.
