As you might imagine, I grew up back in the day when VERY few of us had central A/C. Big box fans, going barefoot on tile floors, and a big pitcher of ice tea in the frig is what made it bearable, and our friends and neighbors lived in similar houses. When I was in high school my parents bought a big window A/C with 20,000 BTU's and we just left our bedroom doors open so the air would cool down overnight, allowing us to finally get good sleep.
My freshman year I lived in an old dorm just like the old dorms at UF - none were air conditioned then, with big old steam radiators for heat in the winter that came on with a really loud clang. We were strongly advised to bring fans. Lots of them. By the time I graduated, most dorms had been retrofitted with A/C, not an easy task for the old dorms the state built early in the 1900's.
Church had no A/C
House had no A/C
School had no A/C
Cars rarely had A/C
I admit I couldn't live here now without it, but we've all gotten "soft" as they say. When we lived up north we never ran the A/C in the summer and people thought we were crazy. Heck, in Michigan and Wisconsin (lived in both states for a time) it was 85 degrees max during the day and 60 at night. Are you kidding me? That's a great spring day in Florida. We just put in ceiling fans in all the rooms and were good to go.
