That's a low cost, unless water vapor condenses inside the house.

And just why do you think air conditioners have drip pans?

Speaking of which, there is some potential cooling assist in the
condensate. The condensate will be about the temp. of the evaporator when
it's formed, that is, rather cool. There is cooling ability both in
warming this water, and in re-evaporating it. Let's say you either use
this water to cool the freon going into the condensor coil or that leaving
the condensor. Which is more efficient (in amount of cooling per kWh)? The
freon going into the condensor is hot, so maybe the water will
re-evaporate, taking with it more heat. Or the condensate cools the freon
leaving the condensor coil, cooling it even further, meaning the freon
entering the evaporator coil will be cooler, meaning the A/C output is
cooler, but it is less likely to evaporate. (Both the warmed condensate
and evaporated condensate are dumped outside)

Any thoughts?
