Why is my Haier HSU-09RS03/R2(SDB) cooling poorly?
- C
  Chelsea CookAug 13, 2025
  Poor cooling in your Haier Air Conditioner can occur due to several reasons. Check if the air filter is dirty and clean it, normally, every 15 days. Ensure there are no obstacles blocking the air inlet or outlet. Verify that the temperature is set correctly and that all doors and windows are closed. Also, consider whether direct sunlight is entering the room (use curtains) or if there are excessive heat sources or too many people in the room.

  When your Haier Air Conditioner is stopped, it will not restart immediately. There is a 3-minute delay to protect the system. This protection circuit also activates if the electric plug is pulled out and reinserted, ensuring the air conditioner's safety.

  If your Haier Air Conditioner doesn't restart immediately after being stopped, it's because the system needs to protect itself. There is a 3-minute delay to protect the system. If you unplug and replug the unit, this protection circuit will also activate for 3 minutes.

Why is my Haier HSU-09RS03/R2(SDB) making noise?
- A
  Amber TerryAug 28, 2025
  Your Haier Air Conditioner may produce a swishing or gurgling noise during operation or when it stops, especially within the first 2-3 minutes after starting, due to refrigerant flowing in the system. A cracking noise during operation is normal, caused by the casing expanding or shrinking with temperature changes. However, if there's a loud noise from airflow, the air filter might be too dirty.

  Stephanie KnoxSep 4, 2025
  The swishing, gurgling, or cracking noises you hear from your Haier Air Conditioner are normal. The swishing or gurgling sound is refrigerant flowing through the system, most noticeable in the first few minutes of operation. The cracking noise comes from the casing expanding or contracting due to temperature fluctuations. However, a significant noise from airflow could indicate a dirty air filter.
