A side note on the evaporative cooler-"swamp cooler" : In Dallas, in the late '50's we had a severe drought, with high temps and lower than normal humidity throughout the summers. Most homes in my neighborhood had no A/C, just attic fans (sucked air thru windows, and out thru the roof gable vents). Others had "swamp coolers", and we were lucky enough to have both. My Grandparents, three houses down, were the only ones to have 2 window A/C units (on really hot nights, I would slip out, and go there!). Well, the "swamp" evaporative coolers worked well with low humidity, especially with a whole-house breeze generated by the attic fan. But, when the humidity from the Gulf (of Mexico) would rise to 50% or more, then it became clammy. Later, in the '60's, we replaced the "swamp cooler" with window A/Cs, as did the rest of my neighbors (none had central air, at least into the 70's). Really liked the muted roar generated by the "swamp cooler" fans , the attic fan, and the window A/Cs (to this day, I sleep better with that background noise...I love the sound in my little trailer, and sleep like a baby!).
