I bought a refridgerant kit to convert my r12 system to a 134a, then I find out that I have to have the r12 discharged by a shop. It kinda defeats the purpose of doing it myself. I want to avoid the whole go to a service station wait all day and then over pay for it, on top of here about all the parts that supposably are needed. I would rather just not have air conditioning if that is what I have to do.

I know that you will not like my opinion but to do the conversion correctly you must change all the service ports and install an under-hood sticker so that R12 Freon is not accidentally installed at a later date and the oils used for R12 and R134a are incompatible so as much as possible of the mineral oil used for R12 must be removed from the system.
This is done by removing the compressor from the car and draining it into a container, replacing the receiver dryer along with the expansion tube or expansion valve, and flushing the condenser, evaporator and lines with a pressurized flushing agent. All of the o-rings removed during this operation must be replaced with a type designed for R134a.
In my opinion all o-rings and hoses in the system except for the liquid line should be replaced during a conversion as some mechanics recommend. Then the system is charged to about 3/4 it's original specification and the rest is just like the standard A/C service. You will definitely find other mechanics with different opinions on how to do a conversion but just replacing fittings and adding a different type of freon just doesn’t work correctly.

Well, by Law, your not supposed to just discharge R12 directly into the atmosphere. Thats why its a licensed only use. Also, its not that expensive to have your system evacuated. Or discharged. I had one done with R12 in it, and it cost $25 at the time. Hopefully not more than that now. Also, just watch for people taking pics of you, when your destroying the Ozone.

If the old system works why do you want to change it? The refrigerant does not ware out. Unless it leaks out it will last forever. If the a/c works just leave it alone, if it does not work then the chances are the refrigerant has already leaked out.
Go to the stem where the hose connects to the system, remove the cap, there is a core inside just like the one in the valve stem on a tire. Take a nail or some small object and slowly push it down. If the system is charged, some will spew out. If nothing comes out then the system is already discharged.

the real issue here is the r12 is real bad for the environment. it might only be a few buck's to have a professional do this. call around.

The people who manufacture and sell those conversion kits should be hung. Are they suggesting that you change the receiver/drier, flush the system out, add the proper oil? I'll bet not.

If you want you’re A/C to function, take it to a certified shop. It's going to cost you around $500
Good Luck. . .
