    mixing r22 & r410a

    What would happen to the subcooling & superheat if you mixed r22 into a r410a A/C system

    That would depend on how much you mixed in.

    But no matter.
    Recovered the mixed gas. Vacuum and recharge with virgin R410A.

    Wait till you see what it cost to get it destroyed.

    The problem is the compressor oils. They don't mix and one type ruins the other.
    No reserve. No retreat. No regrets.

    For those who have fought for it, freedom has a sweetness the protected will never know.

    For the OP's question. Oil isn't the problem.

    If you mix the 2 gases, you end up with a big refrigerant destruction bill.

    In a few more years, I expect this to be a common problem, with gas N go valls that the techs are on performance pay, and ruching ot get to the next call.

    And then with the ones where a friend "use to do HVAC".

    I hate it when that happens. You better go over there tomorrow and recover your coctail and refill it with 410 before the boss finds out.

    If more government is the answer, then it's a really stupid question.

    Problems major. May not work right. 410A runs at higher pressure then r22. Recover all. Pull deep vacuum and you will be better off. Could still have problems down the line depending on how long it was running in the system. Never Mix. Most units say what is to be used in there system when manufactured and what was in it. Comfortmaker units have it posted and what heat pump has pre-charged is for a 15ft line set and matching coil. Else need to add 0.6oz per ft more.

    The hardest part I've found when mixing refrigerants is getting them equally stirred up together. It's tough to get that wooden spoon in there to stir it enough.
