Why is my Haier HSU09XCK Air Conditioner not cooling properly?
- JJennifer RobertsAug 13, 2025
If your Haier Air Conditioner isn't cooling well, several factors could be the cause. Make sure the air filter is clean, as it should be cleaned every 15 days. Check for any obstructions blocking the inlet and outlet. Verify that the temperature is set correctly, and ensure all doors and windows are closed. Also, consider if direct sunlight is entering through the window or if there are excessive heat sources or too many people in the room. Using curtains can also help.
