Why is my Haier HSU-18LTG/022L(W) Air Conditioner not cooling properly?
- A
  Allen ShahAug 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.

Why is my Haier HSU-18LTG/022L(W) Air Conditioner making noise?
- A
  angelaphillipsAug 21, 2025
  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.

  Mary AndradeAug 27, 2025
  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.

  If your Haier Air Conditioner is generating smells, it's likely circulating odors from the room, such as those from furniture or cigarettes. You should investigate the source of these smells.
