Why is my Haier HSU-18LXA03 not cooling well?
- RRebecca PotterJul 31, 2025
Several factors can cause poor cooling in your Haier Air Conditioner. A dirty air filter, which should be cleaned every 15 days, can restrict airflow. Obstacles blocking the inlet and outlet will also reduce cooling efficiency, so remove any obstructions. Ensure the temperature is set correctly and that all doors and windows are closed. Direct sunlight can also impact cooling, so use curtains to block it. Finally, too many heat sources or people in the room can overwhelm the unit's cooling capacity; try to reduce these.
