What to do if the Mijia Air Conditioner Pro Eco A+++ 9K cooling effect is poor?

If the cooling effect of the Mijia Air Conditioner Pro Eco A+++ 9K is poor, please follow these steps:
1. Check the air conditioner settings, turn off Sleep mode, and increase the indoor unit fan speed to improve the cooling effect;
2. Check the environment, including whether there are any heat sources indoors and if the doors and windows are properly closed;
3. Check if the air intake and air outlet of the air conditioner are obstructed to ensure proper airflow;
4. Check if the indoor unit filter is dirty or clogged, and clean the filter;
5. Check if the outdoor temperature is too high (over 43°C), as the cooling effect will decrease under such conditions, which is normal.
If the issue persists after the above checks, please contact the after-sales service for inspection.
