    From looking at these numbers again, it is looking like the orifice is oversized and the unit is overcharged to compensate the flooded evaporator.

    Customer said that it worked fine last year. Before weighing in a fresh charge, the pressures and temperatures were the exact same. I did not check the orifice size in the coil.

    Ran across a unit today that is puzzling me to no end. I am leaning towards the indoor metering device (fixed orifice) being faulty, but I am just not 100% sure. Indoor fan is wired on high speed....

    From a service stand point, that information is irrelevant. I don't measure refrigerant in gallons and quartz. I measure refrigerant in pounds and ounces.
