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

Maybe not. What Joe's pointing to, I'll bet, is the latent heat of
condensation that must be dealt with in the a/c evaporator, on
condensing the moisture there. For a given mass of water, that's
about half the latent heat of boiling the water.

Almost certainly a significant energy expense, never mind that high
humidity indoors is "yucky" (TM) until the water vapor is reduced.

Were you considering only water-damage to house contents other than
a/c air-movers? I'd be slower to dismiss.
