I'm still waiting for our swamp cooler to just fall off the side of our home onto the ground. However, until that happens this ancient swamp machine of at least 8 years continues to function. I replaced the pads for the first time this year and it's blowing some impressive cold air into our home. It's on for less than five hours a day as there is a thermostat hooked up to it. The power draw is about 1/5th that of a compressor based air conditioner. Works great until it gets humid.
