Not according to my shop. I also distinctly remember the compressor
saying R-12 on it. They agreed with the compressor, said that in
order to diagnose/repair the system when I had a problem with it it
had to be converted so they could ensure it had a full charge, they
had no R-12 left. Turns out all I had to replace was a pressure
switch, but that's beside the point...
