    Never ran it in this application, but did run lines for large tonnage AC in pvc, was not fun mainly because it required two 90Deg els on each end.
    Oversized the pvc pipe considerably to give enough room. Suggest you try to keep joints out of it except at the ends if possible.

    How long of a run is it?

    I have done it a few times...it can be a pain. One of the most important things you will need to remember is to ensure that your ends are sealed before you send them thru that chase. (IE..by soldering them closed or cap and tape the ends) The next thing you must ensure is that you leave NO joints in the chase; because you may not be the next one to work on it.

    There are three reasons, I believe that locations have used PVC chases in my experience - one is the one discussed already - that being asthetic.

    Secondly, is the need to prevent moisture buildup or similar things happening when or if lines are inside walls or overhead. For example if the insulation you use for the suction line were over time deteriorate then whatever moisture would leak from them would - theoretically stay within the PVC.

    Finally is the need to protect the lines from the surrounding area that the lines are being run. I have installed lines under the water table and had the lines encased in PVC surrounded by a fire proof foam until the exited the areas that needed protection.
    Hope that helps some! Good luck!
