    R407A

    Hi Guys,
    I'm new to the site and I've read threads about the issues when converting R22 to R407A, but is R407A a good refrigerant? I don't have much experience with refrigerants that have that much glide. When adjusting my A8/A9 valves for low ambient do I take the bubble point?

    R407a is a good refrigerant. No complaints with it so far.

    You'll want to use bubble point on the flooding valves, yes.
