I found using an air conditioner hurts your ability to climatize.
I actually grew accustomed to coastal NC weather, and Florida was no big deal.
After a year or so, I was able to run 10 miles in +90 degree temperatures during black flag days (organized military physical training not allowed) on those days with the 98% humidity at the same time. On those days I enjoyed 10 mile runs in combat boots, flak jacket, utility trousers, cartridge belt, two full canteens, first aid kit, and ammo pouch. They had water buffalos (water tanks) every 1/2 mile or so, for hydration. What is weird in that humidity level is your sweat doesn't seem to evaporate, and at the end, your boots are full of water. I sure miss those days.
When I'd first experienced that heat/humidity, I found it hard to breathe, but conditioning sure makes a huge difference.
It sure made a big difference when we went over for Desert Storm/Shield and I was thankful for the conditioning.
Also, I lived off base, and didn't have the money to afford air conditioning, and at first spent many uncomfortable nights trying to sleep.
If you want to climatize, just slowly back off on the amount of air conditioning you use by raising the temperature a tad. Your energy bill will thank you too.
