Here is what I experienced.
Sacramento area gets hot in summer (102 yesterday), but we do not suffer from the same humidity as Florida. Also, my garage is slightly over 1,000 square feet in size with three, non-insulated metal doors (two single, one double).
Having said this, tried a 12k BTU portable unit that was rated as being effective in cooling, under ideal conditions, 500 sq ft. Not surprisingly, the system kept a portion of the garage somewhat comfortable, but with some shortcomings. Shortcomings involved the lack of an insulated ceiling in my garage and an effective way to vent the unit (have a window in garage, but not of the type you can open). Ultimately, had to vent it by opening the exterior garage door which just more heat in. Also, no portable units are energy star rated which means that are real energy pigs.
Ultimately defaulted to a portable swamp cooler; much lower cost to operate. These only work though in areas with relatively low humidity; suspect not an option for Florida environment.
