  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.

Why is my Haier HSU-09HEK03-R2 making noise?

  The swishing or gurgling noise you hear during operation or when the Haier Air Conditioner stops is the sound of refrigerant flowing in the system. A cracking noise during operation comes from the casing expanding or shrinking due to temperature changes. If there is a big noise from airflow, the air filter may be too dirty.

  Smells are generated because the Haier Air Conditioner circulates smells from the interior air, such as the smell of furniture, paint, or cigarettes.

  In DRY mode, when the room temperature becomes lower than the temperature setting plus 2 degrees Celsius, the Haier Air Conditioner will run intermittently at LOW speed, regardless of the FAN setting.
