How To Check Superheat On Heat Pump. Once the system has been charged, the plastic sheeting is removed from the condenser and orange low voltage wire replaced to switch the heat pump back to heating mode. Getting the correct replacement parts.
Take a pressure reading of the suction line at the evaporator to get refrigerant saturation pressure=temperature. You will plug these into the chart or calculator, and you will get a target superheat generally somewhere between 5 and 25 degrees. Use the dew point temperature on the pressure/temperature chart to obtain the evaporator saturation temperature for superheat, and the bubble point temperature to obtain the condenser saturation temperature to measure subcooling.
