Why is my Mitsubishi Electric Heat Pump emitting white mist?
- SSara ConradSep 1, 2025
A white mist or vapor from your Mitsubishi Electric Heat Pump's indoor unit can occur when the indoor temperature and humidity are high, especially when operation starts. Also, during defrosting mode, cool airflow may blow down and appear like a mist.
