Why is my Haier HSU-24LEK03/R2(DB) Air Conditioner not cooling well?
- GGina FreyAug 8, 2025
There are several reasons why your Haier Air Conditioner might not be cooling effectively. Check if the air filter is dirty and clean it, normally it should be cleaned every 15 days. Ensure there are no obstacles blocking the air inlet and outlet. Verify that the temperature is set correctly. Make sure all doors and windows are closed. Use curtains to block direct sunlight. Reduce heat sources or the number of people in the room.
