Why is my Midea Air Conditioner having poor heating performance?
- F
  flemingjesseAug 27, 2025
  If your Midea Air Conditioner is showing poor heating performance, it could be because the outdoor temperature is extremely low; in this case, use an auxiliary heating device. Also, cold air might be entering through doors and windows; make sure that all doors and windows are closed during use. Finally, there could be low refrigerant due to a leak or long-term use; check for leaks, reseal if necessary, and top off the refrigerant.
