    Last I heard 404a was considered a long term refrigerant.

    Of course they would get rid of it, it's a good widely used refrigerant. Only makes sense to get rid of it.

    On a serious note, I had heard some rumblings about that but I have no solid info.

    I heard they are targeting it in Europe because it has a high GWP (global warming potential). I had the question posed by a produce warehouse customer who has an aging R22 skid that blew a 1 3/8 discharge vibrasorb this fall. Lost 1100 lbs of R22 and wasn't real happy. I am trying to sell him on R404A but he's afraid the same will happen as R22. I figure that about 6 months after I get him to install the R404A unit, the EPA will announce their terminate date. DuPont has a spy watching me.

    I've heard the same thing about it being phased out due to high GWP ratings a few months ago by a local supplier
