Why is my Haier HSU-07LEK113 not cooling well?
- JJames GrantAug 11, 2025
Several factors can cause poor cooling. Ensure the air filter is clean; it should be cleaned every 15 days. Check for obstructions blocking the air inlet and outlet. Verify that the temperature is set correctly, and that all doors and windows are closed. Also, direct sunlight through windows, excessive heat sources, or too many people in the room can affect cooling performance. Consider using curtains to block sunlight.
