There are so many novice technicians that get ‘stumped’ on a system without even checking Subcool or Superheat temperatures…. or if they did check them they checked in the wrong section.

To use our two examples from the previous paragraph, R134a at 0 psig and -5 F has 10 degrees of superheat, and the same refrigerant at the same pressure but at -20 F has 5 degrees of subcooling. These concepts of saturation, superheat, and subcooling are the foundation of all sealed system troubleshooting.

3. Calculate superheat: Subtract the saturation temperature from the suction line temperature (Suction Line Temperature – Saturation Temperature = Superheat). Example: If you have a suction line temperature of 65°F (18.3°C) and saturation temperature at 45°F (7.2°C), the superheat calculation will be as follows: 65°F – 45°F = 20°F ...How to check, measure, and read superheat and subcooling on a central air conditioner unit.

Superheat and Subcooling are determined by the boiling temperature of the substance and unlike water many substances have low boiling temperatures. Recalling that latent heat is the heat which is added to a liquid to cause it to change from a liquid to a gas (boiling) without a change in temperature, let’s go to the next step. ...Good Subcooling Value for R-410A: Similar to superheat, the ideal subcooling value for R-410A can vary depending on factors like system design and operating conditions. However, a common target for R-410A systems is to achieve a subcooling value in the range of 8 to 15 degrees Fahrenheit (°F) or approximately 4.4 to 8.3 degrees Celsius (°C).

The less refrigerant flowing through the system, the less the suction line of the system will cool off. You can have a warm suction line (high superheat) due to low charge, a restriction, or high airflow. This indicator is one of many that you need to consider when diagnosing refrigerant problems. Looking at the pinched hose example, we can see ...1. Low Refrigerant Charge (Low Subcooling) Or High Refrigerant Charge (High Subcooling) The most common cause for non-normal subcooling is a wrong refrigerant charge. If the system is overcharged (too much freon), we will get high subcooling. In the system is undercharged (low refrigerant charge), we will measure low subcooling.If superheat is low and sub-cooling is high: Charge must be adjusted. System overcharged If superheat is high and sub-cooling is high: Could have blockage in coil, orifice or line set. If superheat is low and sub-cooling is low: Orifice could be too big, there is no orifice in the unit of the orifice is stuck and refrigerant is by-passing it.9.
