HFO-1234yf is not expected to be sold by anyone but certified shops. If your going to upgrade your system, start buying R134a now...some auto parts stores have already stopped selling it.
Me? I have a 50# cylinder of R-12 that was given to me after a friend who did HVAC passed away...not planning on converting any time in the future. lol

That is right, I had heard that from an AC tech a few months ago...they said that the new stuff is pretty nasty and hard on parts, too...but its good for the polar bears...I too am considering buying a big jug of 134 to stockpile...
Get your 134 while you can, folks.
