Take it to a pro. Refrigerant is dangerous to yourself, as it immediately freezes anything it comes in contact with, including your eyeballs. On top of that, there are 2 kinds of refrigerant, r12, which is the old kind, and r134a, the new kind. You should not mix these 2, and you should not change them without doing some work. The cooling system also relies on the lines being completely free of water vapor. Doing it yourself without the proper equipment will be near to impossible.
