    There is no drop in replacement. All replacements require review of the system design and maybe modification and retuning.

    I would agree no drop in. There are alternative options but no drop in.

    Apparently if you ask my lead I'm considered the helper due to driver license issues any kind is a replacement. The other day he was adjusting the charge on a 2 ton 410 a split and he had a jug of mo99 attached

    This obviously should never be done under any circumstance I just keep asking myself why does he still work here and make the kind of money he does

    Isn't NU22/R422B for AC or Medium Temp Ref. and One Shot/R422C for Low Temp Ref.? Aren't both are in place of R22? R422C is also in place of R502.
    Why would you still use Hot Shot, an R12 alternative, if it's an HCFC?
