If the cooling performance of the Mijia Air Conditioner Pro Eco 3.5 kW is poor, please follow these steps:
1. Check the air conditioner settings. Turn off the sleep mode and increase the indoor unit’s fan speed to improve cooling performance;
2. Inspect the usage environment. Make sure there are no heat sources indoors and that doors and windows are properly closed;
3. Check whether the air conditioner’s air intake and outlet vents are blocked. Ensure proper airflow;
4. Check if the indoor unit filter is dirty or clogged. Clean the filter if necessary;
5. If the outdoor temperature exceeds 43℃, the cooling performance will naturally decline. This is normal;
6. If the issue persists after these checks, please request after-sales service for inspection.
