Update.

I dropped my car at the House of Imports here in So Cal.
I simply tell them that I want the AC system evac and recharged.
They call me back and tell me that the receiver dryer needs to be replaced and quote me a price of $750.
I asked them to just evac and recharge the system. They wont do it.

What a rip off. I am so pissed right now.
I told them to not do anything and I will pick up the car.
Of course I still have to pay the $115 diagnose fee.
I will never go to the stealer again!
