    Trane Lineset size-conflicting information

    Greetings,
    I am planning to replace our 5 ton AC (XL15i) and the gas furnace(80% XV80). I currently have a 7/8" lineset. Some contracts have said I can stay with the 7/8" (with flush); other have said I must replace with 1 1/8" line. I plan on replacing the lines anyway but I am not sure who's advice to rely on.
    I also checked Trane's specs and I think I have conflicting information there too. Here are 2 Trane PDFs that, to me, are saying 2 different things. The equipment will be a 5 Ton AC with the coil to be either the 4TXCD061BC3HCA or the 4TXCD064BC3HCA (not sure yet).
    The 'Trane Lineset 7-8.pdf' shows a 7/8" is required for a 5 ton.
    The 'Trane Lineset 1 1-8.pdf' shows a 1 1/8" is required for the coils mentioned above, using R410.
    Can someone clarify this for me???
    Thanks... Gary

    1 1/8", the R410A coil comes with a reducer.

    it all depends on each situation i have done both

    on replacements i like to changed but not always the best investment of time and money when you can flush because of location and the length off the run

    on sizing it again it depends on the length
    once you think you've seen it all
    (THINK AGAIN)
    I would rather work for free than be look upon as a thief!!!!!

    I'd agree with beenthere, the 1 1/8" is better. Since you were planning on doing the lineset anyway - there is a possibility that using the 7/8" would reduce the system capacity a bit (I've seen 2% quoted). If the length were extremely short it might not matter.

    If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.

    If you do know, then do. But do it right. Otherwise, you may not be doing it long.
