nothing has cooled like R12 cooled imo...but yes they say it was destroying the big O so then went to R134, NOW that is dangerous : / it’s always something and will never stop!

It’s for certain nothing else equals R-12 so far. I recall having to turn my auto air conditioner off and back on even in 98 degree weather because I could not run it fulltime even at the lowest setting without shivering. Now in really hot weather it runs wide open all the time to try to keep the car cool. The air coming out of an air conditioner could be brought down nearly to the freezing point, now you are lucky to get it down to the low forties. I wish we could go back to R-12.
