Ensure the thermal insulation of the piping and the drain hose is complete. * Improperly connected drainage. Make sure to secure the drainage.

      Joshua GreenAug 26, 2025
      There are several reasons why your Daikin Air Conditioner might not be heating or cooling properly. It could be due to incorrect connection of the electrical wires, which requires you to connect them correctly. Another potential cause is gas leakage, so check for any signs of leakage. Also, ensure that the marks on the wiring and piping for each indoor unit match (room A, room B, room C, room D, room E).
