    I'm going back out there now I suspect the charge is some how low but I don't see how because I weighed the charge exactly. The line set is 25 feet long roughly and I weighed out the recommended 72...

    I also here that propress isn't good for application that are subject to constant vibrations. A voper compression system seems like the worst place to try to use propress.
