  If your Gree Air Conditioner's heating isn't effective, the filter might be dirty or blocked. Check if any doors or windows are open, or if the set temperature is too low. There might be a refrigerant leak, or the outdoor ambient temperature could be lower than -5°C (23°F). An error in the control circuit could also be the cause.
