  If your Mitsubishi Electric Heat Pump isn't heating or cooling water effectively, here are a few things you can check: * Clean the filter of the water piping, as a dirty or clogged filter can reduce flow. * Verify the temperature adjustment and adjust the set temperature accordingly. * Ensure that the outdoor unit has plenty of space around it for proper ventilation.

Why is my Mitsubishi Electric Heat Pump emitting water or vapor from the outdoor unit?
- S
  Steven BeckerAug 15, 2025
  The emission of water or vapor from the outdoor unit of your Mitsubishi Electric Heat Pump can occur due to several reasons: * During cooling mode, water may form and drip from the cool pipes and joints. * During heating mode, water may form and drip from the heat exchanger of the outdoor unit. * During defrosting mode, water on the heat exchanger of the outdoor unit evaporates, and water vapor may be emitted.
