Why is my Daikin FCQ125KVEA Air Conditioner not cooling enough?

  Your Daikin Air Conditioner might not be cooling sufficiently due to several reasons. Check if any obstacles block the air inlet or outlet of the indoor or outdoor unit and remove them to ensure proper ventilation. The air filter might be clogged and require cleaning by a qualified service person. Also, ensure that doors and windows are closed to prevent wind from entering, and use curtains or blinds to block direct sunlight. The cooling effect may also decrease if there are too many people in the room or if there is an excessive heat source.
