I'd like to live in a sustainable building right now. My air conditioner broke yesterday. I mean seriously.. it broke during a heat wave. Thank got my roommate has a small, standing fan. Was my savior.. sort of. But still super hot. There's something dangerous going on with the air conditioner that's huge and bolted into the wall. It doesn't turn off completely- makes humming noises. And when I unplug it, even after a few minutes, makes a spark. Then when I tried to plug it back in, it made another spark so that's when I turned it off for good. Anyone know anything about air conditioners??? Or have an advice???
