      If you're seeing condensation on the front air grille of your Daikin Air Conditioner's indoor unit, it could be due to a couple of reasons: * **High Humidity:** After long operation, air humidity can cause condensation. Try to reduce humidity levels. * **Low Temperature Setting:** If the set temperature is too low, it can cause condensation. Increase the temperature setting and operate the unit at high fan speed.
