Why is my Haier Air Conditioner cooling poorly?

  Jennifer WilsonAug 8, 2025
  Poor cooling in your Haier Air Conditioner can stem from several factors. Check if the air filter is dirty and clean it, ideally every 14 days. Ensure there are no obstructions blocking the inlet and outlet. Verify that the temperature is set correctly. Make sure all doors and windows are closed. Reduce direct sunlight by using curtains. Finally, consider whether there are too many heat sources or people in the room.

Why does my Haier HSU112VHG-G Air Conditioner not restart immediately?
- D
  Devin CisnerosAug 16, 2025
  If your Haier Air Conditioner doesn't restart immediately after being stopped, it's due to a built-in protection mechanism. The unit is designed to wait for 3 minutes before restarting to protect the system. This also applies if the electric plug is pulled out and reinserted; the protection circuit will activate for 3 minutes.

  In DRY mode, the fan speed of your Haier Air Conditioner cannot be manually adjusted. When the room temperature drops below the set temperature +2°C, the unit will run intermittently at LOW speed, regardless of the fan setting.

Why is my Haier Air Conditioner making noise?
- A
  Amber JacksonAug 31, 2025
  The swishing or gurgling noise you hear during or after operating your Haier Air Conditioner is the sound of refrigerant flowing through the system. It’s more noticeable in the first 2-3 minutes after starting the unit. However, a big noise from airflow during operation might indicate that the air filter is too dirty.
