    Confused goodman 5 ton split sys new..equal rise on pressures

    New system provided by homeowner. Upon initial startup pressures equally rose. By the time it got to 250 on liquid and suction I shut it down... so it basically acts like there is a blockage. There are two pistons in the system one inside and one outside. The outside piston is supposedly located in the liquid service port. The thing doesn't even look like a service port..any help would be much appreciated!!

    There is a no DIY rule on this site.

    We can't offer much help to you unless you prove that you are a professional in the field. We have technical forums to discuss matters like this in.


    That said, I don't think that you are looking at a blockage of any sort.

    Let me ask you why you believe this to be indicative of a blockage?

    Explain.


    Also, did you take readings other than pressures?

    I agree I've seen this many times with inexperienced people in the field.

    Heck, I've done it a few times, too.

    I just recognize it a LOT faster than I used to.

    Is the compressor staying on or is it shutting off?

    Why do you think that this was caused by a blockage.

    I want to try to get my head around your thinking so that I can help to correct it.
