Re: 134a how long to go?
I think R134a is one of the lower global warming hfc's so is likely to be around for a while.
Who can say what tomorrow brings?

Re: 134a how long to go?
I agree with monkey that R134a will be around for a good while yet. But that new HFO1234fy (yes its called that) that has been developed for the automotive industry, and it is a straight drop in for R134a.
I have had some dealings with Delphi Automotive who is one of the companies developing it and they said its performance is almost identical. But its quite expensive currently not sure how expensive though.

Re: 134a how long to go?
Regarding R134a last i heard is it forbidden to use in AC for new cars after 2011. That means it will probably be phased out since car-AC is the driver for some kind of refrigerants.
Regarding HFO1234fy.. isnt that flammable? If so it will be a problem for U.S.

Re: 134a how long to go?
That was one of the concerns as well as its toxicity but it has now apparently been proven safe on both accounts

Re: 134a how long to go?
R134a is still common place for a lot of direct drive van and small truck refrigeration units on a fresh or chilled application, they are still selling the units and I am not familiar with any changes in the Thermo King or Carrier product range in the near future so should imagine it will be around for a while yet
