Why is my Haier HSU18VHJ(DB) not cooling properly?

  Poor cooling in your Haier Inverter can stem from several factors. Check if the air filter is dirty and clean it every 15 days. Ensure there are no obstructions blocking the inlet and outlet. Verify that the temperature is set correctly and that all doors and windows are closed. During cooling, block any direct sunlight with curtains. Finally, consider if there are excessive heat sources or too many people in the room.

Why is my Haier HSU18VHJ(DB) Inverter making noise?

  The swishing or gurgling noise you hear from your Haier Inverter during operation or when it stops is the sound of refrigerant flowing through the system. It's most noticeable in the first 2-3 minutes after the unit starts. A cracking noise during operation is caused by the casing expanding or shrinking due to temperature changes. However, if you notice a significant noise from the airflow, the air filter may be too dirty.
