What I'm Being Told...
Is that the older systems set up for R12, will fail if converted to R134 or even the Freeze 12 refrigerant.
I have been repeatedly warned that the R12 systems will only continue to function properly with R12, and that the conversion to R134, or even to Freeze 12 will eventually result in compressor as well as other component failure, and that it is bst to just stay with R12...
My mechainic's bottom line, "Ask them if the will replace whatever components fail due to the conversion".
