Why is my Haier HFU-09H03/R2(DB) cooling poorly?

  If your Haier Air Conditioner isn't cooling well, several factors could be the cause. First, check if the air filter is dirty and clean it, ideally every 15 days. Make sure there are no obstructions blocking the air inlet or outlet. Verify that the temperature is set correctly for cooling. Also, ensure all doors and windows are closed. During cooling, direct sunlight can impact performance, so use curtains. Finally, excessive heat sources or a large number of people in the room can strain the unit's cooling capacity.

  Various noises can come from your Haier Air Conditioner. You might hear swishing or gurgling noises during operation or when it stops; this is just the refrigerant flowing. A cracking noise can occur as the casing expands or shrinks with temperature changes. However, a big noise from airflow could indicate a dirty air filter.
