Factors like system design, ambient conditions, and equipment type influence subcooling requirements. Typically, R410a systems require a subcooling level of 10-15°F (5-8°C). Follow heat as it moves through the system to see if the system is or is not performing as it should. That means understanding and measuring all three types of superheat: evaporator, total, and duct system. 1. Evaporator superheat. To measure evaporator (indoor coil) superheat, first measure the suction line temperature at the evaporator outlet.

The model ASX14 superheat and subcooling accessory head measures refrigerant pressure and temperature simultaneously. It then calculates and displays superheat or subcooling. It has a 1/4” industry standard fitting for actual pressure. A pipe clamp thermocouple is included for temperature. Select R22 or R410A. Select superheat or subcool- This would typically cause a low suction pressure, and a low superheat. In heat mode, a dirty air filter causes low airflow across the condenser. This can cause extremely high head pressure. In heat mode, a dirty outdoor coil can cause a low suction pressure. ... does not work on an R-410A system.
