  Maria BrownAug 12, 2025
  Poor cooling performance in your Haier Air Conditioner can be caused by several factors. Check if the air filter is dirty and clean it every 15 days. Ensure there are no obstructions blocking the air inlet or outlet. Verify that the temperature is set correctly. Make sure all doors and windows are closed, and use curtains to block direct sunlight. Also, consider if there are excessive heat sources or too many people in the room.

Why is my Haier Air Conditioner making noise?
- D
  danielsmithAug 23, 2025
  You might hear swishing or gurgling noises during operation or when the Haier Air Conditioner stops; this is normal and caused by refrigerant flowing through the system. This noise is more noticeable in the first few minutes after starting the unit. A cracking noise during operation is also normal, caused by the casing expanding or shrinking due to temperature changes. However, if there's a significant noise from airflow, the air filter may be too dirty and should be cleaned.
