  Robert BrownAug 12, 2025
  Several factors can cause poor cooling in your Haier Air Conditioner. Check if the air filter is dirty and clean it every 15 days. Ensure there are no obstructions blocking the inlet and outlet. Verify that the temperature is set correctly and that all doors and windows are closed. Also, consider whether direct sunlight is entering through the window (use a curtain) or if there are excessive heat sources or too many people in the room.

Why is my Haier Air Conditioner making noise?

  Stacy JohnsonAug 23, 2025
  You may hear several types of noises from your Haier Air Conditioner. A swishing or gurgling sound is normal and caused by refrigerant flowing through the system. A cracking noise during operation is due to the casing expanding or shrinking with temperature changes. A big noise from air flow in unit operation may indicate a dirty air filter.
