They do sell it, and offices and stores have it, of course, but it's fairly unusual for a home to have it, even fairly upscale homes. You will see in-window units in places that are unbearably hot, but it's sortof like that movie... can't remember which one, where people assume if you have air conditioning, you must have some kind of medical condition.
Maybe it’s just me, but it seems like y’all not having air conditioning for 3-4 months out of the year is kinda like us not having heat for 3-4 months out of the year (although we actually need heat about 5-6 months).
Or maybe it’s just that I can’t stand the thought of not having air conditioning.
