Why is my Haier Air Conditioner cooling poorly?
- J
  Jacob ParkerJul 29, 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 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. During cooling, use curtains to block direct sunlight. Finally, consider if there are too many heat sources or people in the room.

  When a Haier Air Conditioner is stopped, it won't restart immediately until 3 minutes have passed to protect the system. Also, when the electric plug is pulled out and reinserted, the protection circuit will work for 3 minutes.

Why is there noise coming from my Haier AS25THMHRA Air Conditioner?
- R
  Robert CurryAug 15, 2025
  If you hear a big noise from air flow when your Haier Air Conditioner is operating, the air filter may be too dirty. During operation or when stopping, swishing or gurgling noises may occur because of refrigerant flowing in the system. A cracking noise might be heard during operation as the casing expands or shrinks due to temperature changes.
