Do You Have a Swamp Cooler?

A few years ago, I watched a contractor install a swamp cooler (also known as an evaporative cooler) on an elderly woman's roof. Her home, which had previously been uncomfortably, even dangerously hot, was given immediate relief when the evaporative cooler was turned on. Evaporative coolers work by drawing exterior air into special pads soaked with water. The air is cooled by evaporation, and then circulated throughout a room or home. Evaporative coolers, which work best in hot, dry climates, are significantly less expensive and more energy efficient to run than air conditioning units. Do you have one in your home?
