Now Cecil, you can't say that, they brought out R1234YF to save the 
planet for the little children.  Just because the patent expired on 134A 
and Dupont was pushing to replace it with the newly patented material 
had nothing to do with it. Shame on you for thinking they only want the 
money, it's to save the planet...  LOL

This question actually came up at one of the classes on this crap a 
while back, the "Save the planet" answer was the party line, but most of 
us had been through the same BS back when R-12 was dropped and commented 
that at least then Dupont was honest and said that they were pushing 
R134a due to the patent issue.

The one trick is that if the price on the 1234yf doesn't drop a lot, 
there are likely going to be many conversions to R134a. If you pull the 
R1234yf out, fully flush the system and swap out the drier to be sure 
you got all the oil you can recharge with PAG and R134a and have the 
system work just fine as the two are almost identical in operational 
characteristics.

Just don't get caught because the EPA has tagged R1234yf differently, 
it's now considered as part of the emissions system on the vehicles that 
use it because the companies were handed carbon offsets for using it. So 
swapping it out is now a violation of the Clean Air Act.
The fines start at about $10,000.00 after they are done dragging you 
through the system.

As for propane, there was an Australian, Ian MaClaine-Cross pushing his 
hydrocarbon based replacement as a drop in for R12 who managed to blow 
himself up on camera, during a demonstration showing just how safe it was.
