There's a couple gadgets out there that use ultra-fine mist heads to wet down the coild of the heat exchanger on Central air units. I tried it out myself after reading this article about rooftop cooling the same way, and was pleased to see a cooldown in my house from 82 to 77 in 1 hour, something that normally takes 3 hours when i get home on Sunday nights after being out of town.
