Why is my Haier HSU-09HEK03-R2 Air Conditioner not cooling properly?
- GGeoffrey McphersonJul 31, 2025
Poor cooling in your Haier Air Conditioner can stem from several factors. First, check if the air filter is dirty and clean it, typically every 15 days. Ensure there are no obstructions blocking the inlet and outlet. Verify that the temperature is set correctly. Also, make sure all doors and windows are closed, and block any direct sunlight with curtains. Finally, consider if there are too many heat sources or people in the room.
