Why? If level, the water will evaporate. Window ACs should not drip.

It depends on the humidity indoors. I've had a couple of window units
in which the condensate gets splashed on the the condenser by the fan.
Most of the time, it evaporates from the condenser without dripping.

But when it's really humid indoors, there is so much condensate per hour
that some of it ends up dripping from the outside end of the unit.
