Why is my Haier HSU12XCK Air Conditioner cooling poorly?
- LLisa MccormickJul 31, 2025
Poor cooling in your Haier Air Conditioner can stem from several factors. A dirty air filter, which should be cleaned every 15 days, can significantly reduce cooling efficiency. Ensure there are no obstructions blocking the air inlet or outlet. Check if the temperature is set correctly. Open doors or windows can also impact cooling performance. Direct sunlight through the window during cooling operation can increase the heat load (use a curtain). Also, too many heat sources or people in the room can affect cooling.
