Update

OK, so here's where we are with the air conditioner (because I know all of you are eagerly waiting to hear)...
So, Tracy called them ... somehow got it to $650. Remember, this is for a thing that (I'm convinced) THEY CAUSED!
Since I was still pissed, she told me to talk to the owner.
I have to admit I'm not much for confrontation normally, but I was pissed, so I yelled at the guy for a half-hour as he told me that I was a complete idiot for accusing his tech of causing the problem (he didn't say "idiot" but it was inferred).
In the end, I vented ... that was about it.
We still have to pay them $650.
If you ever want to know the name of a good HVAC company, I can tell you who to skip!
