What to do if my Haier Air Conditioner system does not restart immediately?
- C
  Colin PerryJul 31, 2025
  If your Haier Air Conditioner doesn't restart immediately, it could be due to the system's protection mechanisms. When the unit is stopped, it will not restart for 3 minutes to protect the system, so wait for 3 minutes before attempting to restart it. Similarly, if electricity is disconnected and then reconnected, the protection circuit will work for 3 minutes. After reconnecting electricity, wait for 3 minutes before using the air conditioner.

Why is my Haier Air Conditioner making noise?
- M
  mendozakimberlyAug 6, 2025
  There are several reasons why your Haier Air Conditioner might be making noise: * A swishing or gurgling noise is normal during the first 2-3 minutes after the unit has started, due to refrigerant flowing in the system. * A cracking noise may be heard, which is generated by the casing expanding or shrinking due to temperature changes. * If the airflow is creating a loud noise, the air filter may be too dirty. Check and clean the air filter.
