    when its -15°f the receiver will still be doing its job......forming a liquid seal. 75 - 80% full

    Regular condensers require a small % of extra charge to begin flooding the condenser 6-8# total charge generally gets 2+ extra #'s.

    Micro Chanel's get a few extra oz if any.

    If it's -15f outside couldn't you just charge to clear sight glass? Lol. But very good points made. I've done it on a rainy 70f day, only to find the condenser was holding much of the charge, and on a 100f day the unit tripped HP switch. The advice to block condenser to simulate 100f day is a very good idea.

    No because at -30, you'd be low on charge.
