I love my evaporative cooler

I think I make a post like this every year in the spring. Because I live in the desert, it's common here to use evaporative coolers in homes. In my case, I also have a chilled air conditioner unit, but the "swamp cooler" gets the biggest work out.

sourceIt can lower the inside temperature by 20 degrees F and it adds some humidity. That's good for your skin and lungs, but I'll admit in the heat of the summer sometimes that makes it a bit muggy in the house. The rest of the time it is just the right amount of moisture.

Mine is on today and I love that it's cool in the house and it's costing me practically nothing.
