Why is my LG Air Conditioner not cooling properly?

If your LG Air Conditioner isn't cooling well, it might be due to restricted airflow. Ensure there's enough space around the unit and that furniture or curtains aren't blocking the air inlet and outlet. Another reason could be a dirty air filter. Clean it every two weeks. If the room is very hot, give the unit time to cool it down. Also, check for open windows or doors, or open furnace floor registers or cold air returns that could be letting cold air escape. In hot, humid weather, ice might form on the cooling coils, blocking airflow. If this happens, set the controls to High Fan or High Cool and select a warmer temperature.
