The best answer is—as usual—whatever the manufacturer says it should be. If you really NEED a general answer, you can generally expect: High Temp or A/C systems to run 6-14°F of superheat. Medium Temp – 5-10°F. Low Temp – 4-10°F. Some ice machines and other specialty refrigeration may be as low as 3°F of superheat.Welcome to the HVAC Charts On-line Store.

Target subcooling at 80°F = 11.8°F. Target subcooling at 90°F = 11.9°F. Target subcooling at 100°F = 11.9°F. Target subcooling at 100°F = 12.1°F. You can see that this range (from 11.7°F to 12.1°F) is very tight; only 0.4°F difference between very low 70°F outdoor temperature and very high 110°F outdoor temperature. Example of how to fix a 3 ton 16 SEER AC unit running on R-22 freon that has high superheat and low subcooling: Add R-22 refrigerant (but only after you fix the leak, more below). To simplify this, we can say that: High Superheat = Amount of refrigerant in the evaporator coil is too low. Low Subcooling = Amount of refrigerant in the condenser ...Here is a table with these causes that will help us understand why we get low superheat normal subcooling: Low Superheat Causes: Non-Normal Subcooling Causes (High Or Low): Indoor airflow (CFMs) is too low. Oversized AC unit. Outdoor airflow is too low (or condenser coils heat exchange is impeded). High refrigerant charge (overcharged AC unit).a refrigerating system, exclusive of any subcooling or superheating. This term usually describes condensation or evaporation of a zeotrope.
