If we put all of these causes in a neat table, we can quickly see what is causing high superheat and high subcooling in air conditioning units: Low refrigerant charge (undercharged system). Restriction in the liquid line (usually ice). Indoor airflow (CFMs) is too high. Indoor heat load is too high.
Superheat is a way to ensure that the system is boiling off all of the liquid before it exits the evaporator. Refrigeration and air-conditioning systems may produce different superheat readings, but they are all determined the same way: by measuring indoor wet bulb and outdoor dry bulb measurements and using a pressure-temperature chart.
