Haha, I've spent 13 years in houston or on the coast (96-08) and just moved here a few years ago. MUCH drier here, but you get used to it.
The heat was more of an issue in my old office, I had this computer PLUS my x3350 with 2 gpus running seti 24/7 in there for 2 years. In the summer it was just stupid, typically ~ 85f. However, my downstairs is very open and I moved the main rig downt here ~ 6 mos ago. Our living room ceiling is probably 17 ft high or so with tons of windows, ditto the entryway, so 500w or so extra from this one rig isn't really even noticeable. It's usually ~ 70f in winter and 76f in summer, and both of those are easily manageable after those horrible 85f adventures...
This weekend we were just beginning our summer/fall transition, I think it was around 74f and it was extremely nice.
