Oh man. I totally sympathize. Our apartments have these old, crappy AC units and last summer ours broke and the management didn't believe us that it was broken and not just dirty. They had people come up and clean it and we continued to sweat. Finally, after a couple nights of 100 degree heat and humidity I went down to the office and screamed at them to have somebody up there within an hour. I hate doing that, but sometimes you gotta and it got the job done.
