    Someone once said at 200 micron or below, oil will boil off. I totally could not and will not agree.

    If we can't replace the lines, we do not flush unless it's a burn-out. Always empty an 80-CF N2 cylinder at 600-PSI you are good to go. the oldest system done that way is now
    7 years old, no problem.

    I don't believe it's a fan motor. If internal thermal protection, how do you explain the 30-min thing and cycling the power solve the problem for another 30 min?

    One thing I know is if my customer's condenser needs a replacement, he won't be very happy to be forced to upgrade the whole system to R410a. Meanwhile, I have stocked up on jugs of R22.

    without looking into details (tonnage, IDDB/IDWB, air flow...), 250/90 sounds already too low (ODT 98F), but he "bled" it down? Did he vent R22 into the air? Is yes, report him and claim your $25000...

    If a contractor installed it for you, you should get his a$$ back to check it out. If you did it yourself, I am afraid you won't get pro answers here.
