    Why is my LG UT24 not cooling or heating effectively?

      Lauren OliverJul 30, 2025
      Several factors can impact the cooling or heating performance of your LG Air Conditioner. Ensure the air filter is clean by following the air filter cleaning instructions. If the unit was just turned on in a very hot room, allow time for it to cool down. Verify that the temperature setting is correct. Also, check for any obstructions blocking the air inlet or outlet vents.

      The noise you hear from your LG air conditioner could be due to a couple of reasons. A water flowing sound indicates freon flowing inside the unit. A sound like compressed air releasing is the dehumidifying water being processed.
