    Suction line sizing

    Would someone be kind enough to answer question ...I am having a 5 ton coil R22 aprox. 57 feet from condenser to coil.. Condenser is ground level coil is 20 feet higher ... What is prefered diameter of suction line ..7/8 or
    1- 1/8 ?? Is there an advantage to go next size higher or not.. Some manuals list 7/8 as minimum ...others as 1 1/8. Your thoughts Please?

    They might answer if you ask it in the appropriate area instead of one that says, in bold red letters, "DO NOT POST QUESTIONS HERE".
