You will soon have trouble getting R134a. It will soon be banned as cars have been forced to switch to R1234yf since 2016. The problem is not that R1234yf does not cool as good, because it does cool as good. The problem is that it will not be as easy to retrofit from R134a or R12 to R1234yf as it is to retrofit from R12 to R134a.
BTW FWIW, R1234yf is flammable.
I have two very similar cars.
2015 Sonata with R134a and a 2018 Sonata with R1234yf. Both work GREAT. Ice cold air (40F) from the vents.
