  If your Haier Air Conditioner isn't cooling well, several factors could be at play. First, check the air filter; it should be cleaned every 15 days if dirty. Ensure there are no obstructions blocking the air inlet or outlet. Also, verify that the temperature is set correctly and that all doors and windows are closed. Finally, direct sunlight or excessive heat sources in the room can impact cooling performance; use curtains to block sunlight.

  If your Haier Air Conditioner doesn't restart immediately after being stopped, this is normal. To protect the system, there's a 3-minute delay before it can be restarted. If the electric plug is pulled out and reinserted, the protection circuit will also engage for 3 minutes.

What is that noise coming from my Haier 1U18FS2ERA?

  Scott HolmesAug 19, 2025
  If you notice a swishing or gurgling noise during operation or when your Haier Air Conditioner stops, it's likely due to the refrigerant flowing within the system. A cracking noise during operation is typically caused by the casing expanding or shrinking due to temperature fluctuations. However, a big noise from airflow during operation could indicate that the air filter is excessively dirty.
