      ejimenezAug 31, 2025
      If the compressor in your Daikin air conditioner is running continuously, the air filter might be dirty, so clean it. Also, if you're cooling, the temperature setting might be too low, so try increasing it. Conversely, if you're heating, the temperature setting might be too high, so try decreasing it.

      Condensation on the front grille of your Daikin air conditioner's indoor unit is likely due to air humidity after prolonged use, especially if the set temperature is too low. Try increasing the temperature setting and running the unit at a high fan speed.
