Weren't the guys in Walton arguing against A/C at one point?
Yes.
Part of it was tradition, part of it was because Walton was the cheapest dorm to live in on campus because it didn't have AC.
Before Carrier took the concept of thermal expansion and put it in a mechanical unit, the south was still much like the south of the WONA - agrarian, much lower population. Once AC was invented and started to become mainstream, the overall growth of the southern states began.
But even then people lived well into the 70's and 80's in a lot of areas without AC and made it just fine. There are a lot of houses down where I grew up that have AC but rarely use them because the houses were designed without AC and with the trade winds in mind. Warmer inside that I would prefer, but still very tolerable when it's 90 out but it's mid to upper 70's inside when the windows are open to catch the breeze and you have fans keeping air moving inside.
Houses used to have whole house fans too, had one in my house in college. And on days not in August and September, I could fire that fan up and crack the windows open and have a very solid draft through the house and be extremely comfortable without my AC running. Just don't leave the fan on and the windows open when you mow the yard, that was a bad experience.
