Heat pump 410a pressures.

The thermometer shows us that the superheated R-410A vapor is at 54°F temperature. Now we can calculate R-410A superheat: Superheat (R-410A) = 54°F – 51°F = 3°F. In this case, we have a dangerously low 3°F superheat. This presents a risk that the suction line will deliver liquid R-410A to a vapor-only compressor and flood it.The requirement to re-charge an air conditioner or heat pump system might be suggested by cooling coil icing or by complete loss of cooling, or by very low suction pressures, or very low head pressures, but short of those extremes, pressure readings won't tell you if the quantity of refrigerant that's in the system.
