Why is my Daikin FCQ18PAVJU Air Conditioner not cooling enough?
- KKimberly JohnsonAug 11, 2025
If your Daikin Air Conditioner isn't cooling or heating sufficiently, several factors could be at play. Check for obstructions blocking the air inlet or outlet; if present, remove them to ensure proper ventilation. Open doors or windows can also impact performance, so keep them closed. Direct sunlight can also affect the unit's performance, so use curtains or blinds to reduce it. The cooling effect might be reduced if there are too many people in the room or excessive heat sources. Note that clogged air filters can also affect the unit's performance. In this case, consult a qualified service person to clean the air filters.
