    First, are you stating you are a regular homeowner and not a tech?

    Second, the SC will never be on the equipment data plate!

    Then why did you state this "Ive got it covered !" in a earlier post?!?!

    And why, are you trying to help when there are 'true professionals' on this thread trying to help this guy?

    Hey duc read my post.. I know how to charge it I am trying to clarify why it is if you charge the system according to the manual.... Eh.. Read the post I have written it about 8 times. I have only used super heat to charge or adjust Freon.. Based on the OEM Chart for Heil or ICP equip.. this is the only chart I have found. I got this from a school put on by a local supplier. This chart is better than the dinky chart in the installation manual. it is more specific. We have been installing mainly Luxaire or York Equip, with some Heil, Bryant, and a couple goodman. If you read my post I am trying to clarify that I am charging the system correctly because if you follow what it says in manual which I have been told by techs for the manufacturer, and techs at various supply houses where I have bought equip is the way to do it, the system is overcharged most every time. I am trying to determine whether the manual way of doing it is wrong or mabye I am doing something wrong. I Post here for some clarification. If I knew everything I probably would not be asking questions.

    IF this is actually correct, you have two figures that tell you everything you need to know about the systems charge!!!

    That's a 20 degree drop in the suction line from the coil to the condenser!!!

    This should tell you something! Now that it's pointed out to you, do you see something here?

    Read the last sentence in the paragraph above, THEN FOLLOW IT!!!

    How can that suction line lose that much temp between the evap and cond Shouldnt it be gaining temp?

    Bingo!!!

    Now what would be the cause?
    I'll let you think a little so you will likely remember it for next time.
