    Suva 9000 was/is 407c note A suggests amount of MO or ABO in POE. Seems there has been a change in that since 1994.

    This transition is good for business. I cant control at all what the dealers do. Some will go to the end of the earth to repair before even offering a common sense replacement. These blends suck even when put
    when on top of even traces of mineral oil yes

    In the desert 407c can have a hard time, given the high head pressure
    Some limits need replaced due to a 355 head pressure in the middle of summer. running on a r22 designed system with r22 limits.
    As well as condenser coils on medium temp, they're sometimes just too small

    So you just added 4lbs of r22 without repairing the leak.

    That would be illegal to even top up here in Ontario. The system must be proven leak free.

    We don't have those rules here, eh.

    But before we learned to walk we had learned to cross check properly, eh
