    R410a instead of R22

    Just curious and like experimenting. I currently have a 12 year old R22 3 ton Goodman split system in decent condition sitting at my shop. We took it out during a changeout, the cap tube on reversing valve had broken off from the body and they decided time for a new one. Anyway, I'm curious. What would happen if I was to hookup this system and recharge with 410a? I'd change the piston I'm sure and would have to experiment to find the best size, but would it cool? Less capacity? Blow up in a huge cloud of smoke and EPA restricted mess? Anyone ever done this before?

    Maybe even a big boom and playing find the digits as fingers are blown off.

    I am surprised how folks can goof that up.
