Why is my Heinner Air Conditioner's heating performance poor?
- J
  jamiecookeAug 26, 2025
  If your Heinner Air Conditioner is not heating well, it could be due to a few reasons. If the outdoor temperature is extremely low, consider using an auxiliary heating device. Ensure that all doors and windows are closed to prevent cold air from entering. Additionally, low refrigerant levels due to leaks or long-term use can affect heating performance; check for leaks, reseal if necessary, and top off the refrigerant.
