That sucks. The same thing happened to me the begining of July, and it's still not fixed. We have a 30 year old central air/heater unit, and the compressor went out. Some new law about freon won't let them just replace the compressor, so we need a whole new unit for $4k. I've been melting all summer, laid off and stuck in a humid, 86 degree condo. We aren't allowed to put in window units.
