Well basically you will have to take every single drop of R-12 out. Make sure its real clean in there and put it under vacuum for a while to make sure there is no leaks. You dont have to replace any of the o-rings in the system. You will also have to change the oil in the compressor and get new fittings for your service points. R-12 is screw on and 134a is quick disconnect. But why are you changing over anyway? R-12 is actually colder. I know its expensive and can be hard to find.

You will also need to replace the receiver/dryer (or at least you should......whether or not you HAVE to I'm not sure). But around here, R-12 isnt hard to find (if you can find someone who does hvac for a living). Even at the shops around town, it is still cheaper to do a reseal and recharge with R-12 than to convert (from the people I have talked to).

Yeah you are right about the reciever/dryer, I left that out. Yeah its easy when you have your IMACA certification too.
