    Why does my Daikin FTXS35CVMB8 smell?
    • W
      wisejustinSep 3, 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.
