Why is my Haier HSU-18LTZ/022L(W) Air Conditioner not cooling properly?
- M
  Mr. Eric RiceAug 9, 2025
  Poor cooling in your Haier Air Conditioner can stem from several factors. First, ensure the air filter is clean. Obstacles blocking the inlet and outlet can also hinder performance, so clear them away. Verify that the temperature is set correctly and that all doors and windows are closed. Direct sunlight can impact cooling efficiency, so use curtains to block it. Finally, consider reducing heat sources or the number of people in the room.

  A swishing or gurgling noise from your Haier Air Conditioner during operation or after stopping is normal, caused by refrigerant flow, especially noticeable in the first few minutes after starting. A cracking noise during operation can be due to the casing expanding or shrinking with temperature changes. However, a big noise from airflow may indicate a dirty air filter, which should be cleaned or inspected.

  When your Haier Air Conditioner is stopped, it won't restart immediately for about 3 minutes. This is a protection mechanism. If you unplug and re-plug the unit, this protection circuit activates for 3 minutes to safeguard the air conditioner.
