    Has oil been added to the unit lately? Are the evaporator tubes clean? Has refrigerant been added to the unit? Is the EEV working properly?

    When the discharge temp was low and the discharge superheat was low, what was the expansion valve doing and what was it's position. Was it running in extended unloading?
