I live in the southeast.
It is crazy hot and humid here, and we use the air conditioning about ten months out of the year, I would guess. BUt when I was a kid, a very young kid, I lived in the northeast. I am pretty sure there was no such thing as air conditioning in that neck of the woods. We lived in a fairly affluent area, and I don’t remember anyone ever talking about air conditioning in the summer. Of course, back in those days, kids didn’t pay attention to heating and cooling. I’m positive my school didn’t have a/c either. Try to have a school with air conditioning nowadays, and you will have a thousand whining kids on your hands. But we thought nothing of it. Anyway, there is one thing I remember about heating the house back in those days. We had a furnace with radiators. The reason I remember that is because I would go outside and play in the snow, and when I came back inside, my mom would tell me to put my mittens on the radiator to dry. Then, when it was time to go outside again, I would grab up those nice warm, dry mittens and back out to building snowmen and sledding down the hill. My mom eventually moved us kids down to the southeastern part of the country, so no more snow and no more mittens and no more gigantic heating bill for my mom. We traded in the heating for air conditioning, but I paid no attention to a/c. My mom gave me a very happy childhood, despite the fact that my dad had died when I was just a toddler.
