We need to replace the AC compressor (yes, we are sure), and have the system refurbished/cleaned out etc. Service locations want to convert the system to the newer refrigerant, instead of using the old R12. A few years back, we had this done on an 84 BMW and were lest than satisfied with the temp change.
1. Any experiences here with converting the older systems, and satisfaction?
2. If we do convert, are there any corrosion issues with the newer refrigerant?
Thanks.
