Howdy yall, what is a swamp cooler? I used to have a buddy that said he would put one in his backyard for barbecues and such but I'm not sure how it would be beneficial. I'm from Kansas so we don't have these things here that I'm aware of and I was curious as to how they worked. Now before anybody gives a smart@ss answer, I'm a seasoned hvac vet, so no need to dumb it down. Thanks guys.
