    1.5 ton A/C with a 90' riser. Hope that suction line is only 1/2"(A velocity of roughly 1440FPM). Other wise virtually have no oil return.

    Guessing you did use a trap at the bottom of the riser, and an inverted trap at the top of the riser on all of the long line sets?

    How many times must one fix something before it is fixed?
