Questions and Answers

    Mr. Bryan DanielsAug 19, 2025
    Why is my Daikin Air Conditioner outdoor unit leaking water?
    • S
      scottreyesAug 19, 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 FTYN35CVMB9 smell?
    • T
      tmahoneyAug 22, 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.

      If your Daikin Air Conditioner isn't cooling or heating well, check these: * Ensure the air filters are clean. * Remove any obstructions blocking the air inlet or outlet of the indoor and outdoor units. * Verify the temperature setting is correct. * Make sure all windows and doors are closed. * Confirm the airflow rate and direction are appropriately set. * Check if the unit is set to INTELLIGENT EYE mode.

      For system protection, the air conditioner may stop operating due to a sudden large voltage fluctuation. It will automatically resume operation in about 3 minutes.

    Why is the Daikin Air Conditioner outdoor fan running when it's off?
    • R
      Richard HuertaSep 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 Air Conditioner?
    • M
      Ms. Christine ColeSep 7, 2025
      This happens when the air in the room is cooled into mist by the cold air flow during cooling operation.
