    R32 is the green alternative, but I cant source it in the US

    Howdy all, Ive been researching all evening for my most recent project and it keeps leading me back to these forums. That being said here is my issue.

    Im modifying a complete AC unit and I cant find the original refrigerant anywhere.

    Does anyone know where to source some R32 in the US?

    It's going in Amana PTACs and other small units. Daikin, #1 in the world, is pushing hard.

    Carrier is pushing R454b (I think Trane too) for the future and it is also A2L.

    Only allowed a few Oz (8 i believe) total charge unless the rules have changed again.

    Installed a Cooper Hunter air conditioner a couple of days ago so it already came with the R32. Although frankly speaking I don't see any difference with R410A

    Looks like A2Ls are coming soon

    R-32 has been used by Daikin since 2012. They have over 25 million R-32 units in operation in other countries. Yes it is an A2L. Yes we will have to learn about it, but if you quit learning in this industry, you soon fall behind.
    It has been difficult to find in the USA, but that will change.
    The difference when compared to R-410a is that R-32 has 2/3 less Global Warming Potential and has a slightly high COP.
    R-32 also requires less of it to do the same job as R-410a.
    So, we need less of it. It is slightly more efficient. It has zero Ozone Depletion Potential (ODP). It has 2/3 less (GWP).
    Other companies are trying to come up with their own replacements for R-410a. One of those is YF1234, also an A2L.
    I think we better get ready to learn all about A2Ls.

    for Jimship.
    I have sent a request to Daikin about the availability of R-32 in the USA.
    I don't know how or if they will reply.
    If I get any information from them, I will reply to the forum.

    To go a little further, R410a is a 50/50 blend of R32 and R125. The R125 gave it the higher GWP, lower COP, but also lowered the flammability rating.

    Thank you Dupont.
