Use less energy to cool your home and get cash back.

As energy efficiency gains in popularity so do evaporative coolers, which can use up to 75 percent less electricity than central air conditioners to cool the same square footage. Evaporative coolers cool outdoor air by passing it over water-saturated pads, causing the water to evaporate into it. Cooler air is directed into your home, pushing the warmer air out! Because the technology is simpler, they can cost half as much to buy as a comparable air conditioner. And the best part is that you don't have to sacrifice any comfort. Your home will be cool and comfortable all summer long.
