    Service Tech's numbers...

    I have a Goodman 12 seer, 5 ton unit in a 2100 sq ft house with 9 ft. ceilings; house was built in 2000.


    Disch Press: 325
    Suct Press: 75
    Super: 8* F
    Sub-Cool: 13* F
    T-Indoor: 20
    Ambient: 109

    What exactly do these tell me?

    Well, first of all - that's you going to freeze to death soon

    You better bundle up.

    Obviously your unit is wildly oversized - if it can produce an 89 degree different to ambient.

    My guess is the "T-indoor" is the delta T, not the indoor temperature.

    How many times must one fix something before it is fixed?

    No. Same response - "Unit is working at maximum efficiency".

    No, "X is broken, need to fix it." Or "Unit is toast, need a new unit".

    Just bend me over, take my money.

    It means your stat is set too low.

    Without knowing air flow and ID detlas, it doesn't tell much.

    Seems like they say it's running OK

    Why do you want to know? Are you having performance issues?

    Those are the standard things which a service tech would check to verify that the system is working well.

    Oh, you meant allowed to.

    You can explain them. And then if you get your hands slapped. We'll know were not allowed too.
