Is R12 and R134a the same?
The molecule size of R134a is smaller than that of R12 , so there was concern that R134a could leak out through the hoses and flare fittings that R12 systems used. R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak.
Does R12 cool better than R134a?
Understand that R12 has its advantages. R12 can blow 6 to 7 degrees cooler than R134a and is 15% more efficient . R134a systems require larger condensers and higher operating pressures than R12 systems because R134a doesn’t have as high of a heat transfer rate as R12 (which has a heavier molecular size than R134a).
