How to Check Subcooling. Attach the thermometer to the liquid line. This time, near the condenser. Then take the head pressure in Psi and convert it to the temperature on the pressure/temperature chart. Assuming you are dealing with a R22 system, let’s say the head pressure is 260Psi. This will convert to 120F. Subtract the two numbers to get the subcooling. For example, 275 psi head pressure on an R-22 system converts to 124°F. The liquid line temperature is 88°F. Subtracting the two numbers gives 36°F. High superheat and high subcooling indicates a problem with the metering device. Being able to measure refrigerant Subcool and Superheat are essential for diagnosing and correcting an air conditioning or refrigeration unit.
