Why is my Haier 2HUM18HC03 cooling poorly?
- RRobert 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.
