  Several factors can cause poor cooling in your Haier Air Conditioner. Check the following: * Ensure the air filter is clean; it should be cleaned every 15 days. * Make sure there are no obstructions blocking the air inlet and outlet. * Verify that the temperature is set correctly. * Close any open doors or windows. * Block direct sunlight with curtains. * Reduce heat sources or the number of people in the room.

Why does my Haier HSU-18CI03 - annexe 1 Air Conditioner make so much noise?
- W
  William ShawAug 14, 2025
  Your Haier Air Conditioner might produce different noises during its operation. A swishing or gurgling sound, more noticeable in the first few minutes, comes from the refrigerant flowing. A cracking noise occurs as the casing expands or shrinks due to temperature changes. If there is a big noise from airflow, the air filter may be too dirty.
