R32 is the green alternative, but I can’t source it in the US

[Thejimshep]

Howdy all, I’ve 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.

I’m modifying a complete AC unit and I can’t find the original refrigerant anywhere.

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

Probably No Where. Its classified A2L flammable.

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.
