Yes, I remember Ike and suggesting you to get a window a/c for your garage when the weather’s hot, then for your house, when the power has failed and you’ve switched off power to your panel and back-fed power from your gas fired emergency generator. I haven’t had to use mine for 10 years but I fire up the generator every hurricane season ... which I’ll be doing this weekend to test it ... :o)
We do have a window unit now. It is mostly used as a back up for when either the upstairs or downstairs AC goes out.
Following Ike, the temp dropped enough to be ok with fans. I got a portable gen set, back fed the power panel and we managed okay.
