    Why is my Daikin ARXH35CVMB9 Air Conditioner outdoor unit leaking water?
    • P
      Patricia RobersonAug 14, 2025
      In HEAT mode, the frost on the outdoor unit melts into water or steam during defrost operation. In COOL or DRY mode, moisture in the air condenses into water on the cool surface of the outdoor unit piping and drips.

      Peter WilsonAug 17, 2025
      The Daikin Air Conditioner may emit odors because smells from the room, furniture, or cigarettes have been absorbed into the unit and are being discharged with the airflow. It is recommended to have the indoor unit cleaned by a technician. Consult the service shop where you bought the air conditioner.
