He's right. If you have no clue about how to do this, you're gonna learn the hard way - and by that, I mean it's going to cost you a pile to fix what you did wrong.

You probably have R12, take it to an independent. First question is: why do you have no freon in the system? And once the leak is found (using a "sniffer" is the best way - garages have them), then you can fix the leak and refill the system.
