Why is my Haier HSU-26HEK03/R2(DB)/I Air Conditioner cooling poorly?

  Several factors can cause poor cooling in your Haier Air Conditioner. The air filter might be dirty and require cleaning every 15 days. Ensure there are no obstacles blocking the air inlet or outlet. Verify that the temperature is set correctly and that all doors and windows are closed. Direct sunlight through the window can also impact cooling performance, so use curtains. Finally, too many heat sources or people in the room can strain the unit's cooling capacity.

What to do if my Haier HSU-26HEK03/R2(DB)/I is making noises?
- A
  Allen PrinceAug 11, 2025
  During operation or when the Haier Air Conditioner stops, a swishing or gurgling noise might be heard due to the refrigerant in the system; this is more noticeable a few minutes after starting. A cracking noise during operation may also occur as the casing expands or shrinks with temperature changes. Also, check if the air filter is dirty, as this may cause noise. Normally it should be cleaned every 15 days.
