    Yes, It should work OK
    R12 and R409 TEV is the same. Why are you changing. Have you had a gas leak or a compressor burn out.
    Of its a burnout the it would be worth checking the orrice. But apart from that its the usual.
    Change drier(s) vac out and regas, check youre pressures before you fully charge if doing so by weight as quite often you will need to charge at 10% less with the new blend
