Gotta say, staying temporarily in central FL myself (Wildwood), I think a conditioned third party data center would probably be your best option for a larger set up.
Just running a couple of S7's at my brothers place last summer I had to come up with a Rube Goldberg setup -- took the doors off of an older mini fridge and put it in a well insulated closet with the miners, along with a butt load of fans and a small dehumidifier. Worked out pretty well, but at the time I was running at a calculated loss of about 15% due to power costs ($0.10 per kWh at the time).
I could only justify mining due to my unwavering faith that BTC would climb well above $400 at some not to distant future point. (And yep it suuure did, wish I had held on to more than I did).
When it gets to be 97 degrees and 75% humidity everyday cooling becomes a very expensive proposition for mining rigs.
