Subcooling is the same temperature difference on the high side. “In the example given earlier, suction pressure of 118 psi converts to a saturated temperature of 40°. If the suction gas is 50°, then there is 10° of superheat,” he said. “Too much superheat means the compressor is not being cooled properly and can overheat.Here’s the step-by-step guide: Prior to subcooling measurement, the AC unit should be off for at least 30 minutes. This will equalize the refrigerant pressure throughout the unit (lines, coils) since the refrigerant is in a saturated state (mixture of vapor and liquid). Let the air out of the HVAC gauge. Open the vent, listen to that ...Robo stated it clear, the normal superheat for a residential system can and will vary and some charts go even further than he stated 2-45 degrees. That answer above drives the point, if you do not know the evaporator load, you can not predict the superheat. Reply. 06-02-2011, 06:58 PM #14. hvacvegas.4) Actual line temperature should = chart temperature above. 5) If more than 5 degrees over, add charge to decrease line temperature. 6) If more than 5 degrees under, remove charge to increase line temperature.

1. Take the low side pressure reading from your gauges and convert it to temperature using chart or gauge. 2. Then take the temperature of the Suction line as close to the condensing section as possible stay at least 6 inches from compressor. 3. Take the difference between the above readings (Suction line temp – Saturation temp) 4. Even if a system charge is available, you want to check superheat. And you want to check subcooling, more so as a reality check. 30ºF subcooling suggests to me that your orifice is too small. If we have data, let’s look at data.
