Why is my Haier HFU-09H03/R2(DB) cooling poorly?
- DDeanna HubbardAug 1, 2025
If your Haier Air Conditioner isn't cooling well, several factors could be the cause. First, check if the air filter is dirty and clean it, ideally every 15 days. Make sure there are no obstructions blocking the air inlet or outlet. Verify that the temperature is set correctly for cooling. Also, ensure all doors and windows are closed. During cooling, direct sunlight can impact performance, so use curtains. Finally, excessive heat sources or a large number of people in the room can strain the unit's cooling capacity.
