    New A/C compressor start up question.

    Installed new A/C system this winter. Installer put off checking system until the weather warms up in washington dc. My question is what type of test/s/ should the installer make to insure the correct amount of refrigerant was added to the system. From reading prior posts it appears just measuring the system with gagues does not appear to be enough. The unit is an infinity 4 ton compressor paired with an infinity gas furnace . Thanks

    CFM of air flow will be established first.

    Pressures and temperatures will be established to meet Mfg. specs.

    Line voltage and load voltage, along with amperage will be established to be within specs.

    Condensate drain line will be tested.

    System capacity will be verified, and documented.

    I applaud you for choosing a contractor who is going about it the right way. If he has informed you that he needs to wait until its warm enough to test correctly, you dont need to worry about his procedures. He knows what he is doing.

    Thats not 100% true.
    Good chance he's a quality contractor. But not a 100% guaranty.

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