No they are not as good as the old systems. The operating pressures of R-134A are different than R-12 were..consequently the boiling temperatures are different, the boiling temp of R-12 is -28.6 degrees if my memory serves me correctly and it is higher for R-134A..so the heat transfer in the new systems is not as efficient as with R-12...BTW they still manufacture R-12 in Mexico..:^))

More than a lust for change, we ought to be grateful for what we already possess.
