Why is my Haier HSU-09CK2S3 Air Conditioner cooling poorly?
- BBetty VasquezAug 8, 2025
Poor cooling in your Haier Air Conditioner can stem from several factors. First, check if the air filter is dirty and clean it, ideally every 15 days. Ensure there are no obstructions blocking the air inlet or outlet. Verify that the temperature is set correctly and that all doors and windows are closed tightly. Direct sunlight can also impact cooling efficiency, so use curtains to block it. Finally, consider if there are excessive heat sources or too many people in the room.
