Ken, you beat me to it. I just got back from my lunch break and I checked the air filter and it's filthy! That's the first thing I'll replace when I get back from my vacation. Unfortunately I'm going on this 2-week vacation tomorrow and I'll miss my cars.
About the AC, I did get it to work on my way to lunch and it was blowing cold, but on the way back it was blowing warm again.
