    Why does mist come out of my Daikin FTXS15LVJU indoor unit?
    • G
      Gregory WilsonAug 25, 2025
      Mist coming from the indoor unit of your Daikin Air Conditioner can occur for two reasons: * During COOL operation, room air may be cooled into mist by the cold airflow. * During defrosting, the air in the room is cooled by the heat exchanger and becomes mist.

    • M
      Margaret HunterAug 27, 2025

    Why does Daikin Air Conditioner indoor unit gives out odor?
    • C
      Christina BryantAug 31, 2025
      If your Daikin Air Conditioner's indoor unit emits an odor, it's likely due to smells from the room, furniture, or cigarettes absorbed into the unit and discharged with the airflow. If this occurs, have the indoor unit cleaned by a technician from the service shop where you bought the air conditioner.
