    • C
      Chad HillAug 13, 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 obstacles blocking the inlet and outlet. Verify the temperature is set correctly. Make sure all doors and windows are closed, and use curtains to block direct sunlight. Also, consider if there are excessive heat sources or too many people in the room.

    Why does my Haier HSU-09LEK03/R2(DB) make noise?
    • C
      cheryl65Aug 31, 2025
      During operation, a swishing or gurgling noise may be heard due to refrigerant flowing in the system; this is more noticeable in the first 2-3 minutes after starting. A cracking noise might be heard due to the casing expanding or shrinking with temperature changes. If there is a big noise from airflow, the air filter may be too dirty.
