I'm curious.... what are you guys going to do if your "Dura-cool" systems need to be discharged in order to service the compressor, expansion value of hoses at some point in the future?

All of these alternative R12 blends require dedicated seperate A/C service equipment. Do you have an A/C service shop that will service a "Dura-Cool" system? Around here nobody will touch a system unless its R12 or R134.
