    Why is my Daikin RXH35CAVMB Air Conditioner outdoor unit leaking water?
    • C
      Corey KnightAug 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.

    Why does my Daikin Air Conditioner smell?

      Lori PatelAug 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.

    Why is the Daikin Air Conditioner outdoor fan running when it's off?
    • G
      Gary GarciaSep 5, 2025
      After operation is stopped, the outdoor fan may continue rotating for another 60 seconds for system protection. Also, when the outdoor temperature is very high, the outdoor fan might start rotating for system protection even when the air conditioner is not in operation.

    Why does mist come out of my Daikin RXH35CAVMB?

      Joseph HooperSep 9, 2025
      This happens when the air in the room is cooled into mist by the cold air flow during cooling operation.
