How do I Retrofit my Air Conditioning System?

The Retrofit kits that you find at Wal-mart come with instructions of there own but there are a few things it doesn't tell you. Like, you need to completely flush the air conditioning system of all R-12. R-12 and R134a can not be in the same system or it will lock up the compressor. Also, you need to replace the accumulator and orifice tube at he same time before following the instructions that came with the retrofit kit.
