I'm sure most start ups in Miami have A/C, so I'm not sure what your concern is. Most apartments too. Anyway, I live in an area that reaches 43c in the summer and -6c in the winter. When I first moved here it definitely threw me off, but I got acclimated to it quickly.
As someone who grew up in Milwaukee and moved to Charleston, I agree 100%. One of my largest clients is in Milwaukee now and I can say definitively that I have lost all tolerance for that bitter cold. And to all you Canadians living north of the wall... I don't know how you do it.
For whatever reason the sun in Canada really seems to burn(at least in Toronto area) and it can get really humid in the summers. But in the winter you can always just bundle up and feel comfortable.
