Iirc from my time in HVAC 134 and 12 in the newer systems use different compressor oils and some other minor things so idk if it would work. Can't remember off the top of my head
I would love to get my hands in an old system. Sounds like they would be much better to have.
Thanks for the input.
Idk if you even can anymore. With mobile hvac the cars themselves are designed to be obsolete in 5 or 10 years. So the older stuff is now really obsolete, like v belt compressor clutch pulleys instead of serpentine belt, etc
With residential and the switch to r410A, we cleared all those out back in 2009 at the place I worked so idk how you'd find a NIB air conditioner and coil unless someone had sat on one
