We have been having heat waves here. And this last one our AC decided to stop working for us. Luckily I get to go to work in an air conditioned office each day. But Bruce had to deal with the heat at home. He used a portable AC unit he has for when he brews beer. He hooked it up in the kitchen so it would blow directly on him.
We have a whole house fan. So in the morning before it heats up he would open all the windows/doors and turn it on. Then when it cools off at night (if it does) we turn it on.
He only turns on the AC if it gets super hot in the house. He pays the electric bill, not me! LOL

I never realized how much I like AC until we didn't have it when we needed it!
I was about to go sit in the dogs kiddie pool. And Bruce would hose himself off while working in the garden. Yes, he's crazy and worked in the garden in 100 degree weather!
