Not sure what your budget is, but you might look into a room A/C unit. They have various sizes/BTU ratings that will cool larger areas. I looked into them for my garage where I keep my rats, as I'm having the same issue thanks to this incessant heat. I also bought several fans to circulate the air and create an artificial breeze. They aren't great but they're doing the job and keeping things a balmy high 80's in my garage. The room A/C units would still need to be vented to the outside, through a window or another opening and they're pretty expensive, so that might be a last resort. This heat SUCKS!, but every time I think that, I remember I'm not 5,000 miles from home, carrying a 70+ pound rucksack having people shoot at me...

Sorry for your troubles, hopefully this heat will break soon and things will even back out. Good luck!
