Check the data plate or the table inside the cover for the subcooling for the specific model/tonnage. Make sure airflow is right, charge fixed orifice by superheat, TXV by subcooling. After getting the subcooling right you can check the superheat to make sure the TXV is working. 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 ...

A question that I get asked frequently is “Can I check the charge of a mini-split ductless unit with superheat and subcooling the same way I do on a conventional air conditioner or heat pump?". The answer is not exactly, but you can do some troubleshooting. A mini-split differs from a standard central air conditioning system in a …Continue the process until the system has been determined to be leak-free. Connect the vapor-line and liquid-line pressure taps to a vacuum pump and micron meter. This step is also almost always omitted.

Negative Superheat. Superheat is the temperature gained in the refrigerant once it has completely boiled into a vapor. When it is still boiling, it will be in a mixed state and will be at saturation temperature for that given pressure. Zero superheat is something you will often see when a system has a flooded coil; zero superheat indicates that ...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.

To check superheat on a R-410A system, measure the temperature of the refrigerant gas leaving the evaporator and determine the saturation temperature at the corresponding evaporator pressure. What are the two types of superheat?
