    A/C units rooftop 1.5 to 2 tons, evaperator does not have schrader valve at evap.I can not measure PSI of low side,
    can I just measure it at the compresor, can I add 2-3 PSI
    for an average pressure loss in the refrigerant line from the
    evaporator to the compressor.Now if that's so,I would be ading PSI to the low side compresor reading,

    if I were to do this on the high side at compresor to evaperator will I be substacting PSI instead of adding ?

    Thanks again
    So why are you still here, asking technical HVAC questions?

    And how did you get your creditials?
    Or better yet, why did you feel like you had the right to apply for a pro's membership?

Superheat at the condenser is what you are most concerned about unless you are trying to diagnose a flaky TEV or suction line restriction.
    Superheat is not measured at the condenser but subcooling is. Superheat is measured on the low-side.

    This guy is not in the HVAC industry. He is a DIY all the way!

    Talking

    When I said condenser, I was referring to the condensing unit in a residential split system. The low side of the outdoor unit that is...Hee Hee

    Boy are you persistent,

    you do make me laugh !!!!

    That's a good thing,

    jultzya, I am a professional HVAC repair person, I am servicing 20 unit apartemant A/C, as well as other handy man stuff.

    My credentials are mostly learned from this good site and some books.

    I am not a DIY,

    by the way , the A/C I installed in my house (attic)works fine, the heat is a blast! only problem was with the condesation not draining properly fixed that!

    No leaks, cools fine, heat is great, duct work seems to be very well balanced,

    This was a hard job for 1 person to do,I do no recomend it
    to anyone......

    Are you still not convinced ????
