    Copper tube sizing

    Why is 3/4 O.D. copper NOT listed in the engineering guide for refrigeration? Such as,a Copelaweld mn#F3AD-0201-CFV cond unit,R-22,@+20 evap produces 14,550 btu's.The engineering guide suggests 5/8 OD for up to 25' and 7/8 OD for upto 50'.I slip in 3/4OD copper for the actual 35' run .Am I short changing myself? Thanks To All!

    Duh, my bad!

    I should have read your question more carefully...and rambled about what you obviously well know already :+

    Best answer I can give (and still be right) is:

    I dunno!

    :)

    Good question though...
