If it were just me I'd be out in a heartbeat, but I've got a wife, a 11.5yo kid, a grumpy antisocial 72yo ghoul, and an antisocial 13yo rat dog to consider as well, so that complicates the calculus.
Renting doesn't appear feasible, but we're going to experiment with buying a unit (which we may have application for down the line) and see what that does
My sympathies. We had a hard time last year when it was 93 outside and our A/C stopped working. I got a spray bottle full of water and kept spraying myself while sitting in front of a fan.
