Audi Repair: A/C problem, freon, hot days

Question
I just recently had my air conditioner recharged and now after it runs about 30 minutes and there is a dark vapor or smoke that comes from my ac grills.  It smells but not like smoke.  What is it and should I call the repair shop?

Answer
hello
sometime when A/C gets very cold it starts making smoke(it is OK on very hot days) You can try to rise temperature and see if it goes away. If not , maybe there is to much freon in system? Pressure needs to be checked.
good luck                           pltech
