As this dampness has no dissolved minerals in it, it will not likely cause mineral buildup over the coils.

In a very thermodynamically shut system, any electricity dissipated into the system that is currently being taken care of in a set temperature (which happens to be a standard method of operation for modern air conditioners) requires that the speed of Electrical power elimination with the air conditioner boost.
