Yes we have AC. Some -- but closer to a "few" rather than most -- have
swamp coolers but they're simply a form of air cooling limited to about 20
degrees of cooling. When temperature get over 100, 20 degrees isn't enough.
But we're talking about a different animal here. A WH fan "moves" existing
cool air supplementing AC at a much, much cheaper cost.
