How to check superheat 410a

Measure System Conditions: Measure temperature and pressure at the evaporator outlet (for superheat) and condenser outlet (for subcooling). Calculate Superheat/Subcooling: Use the P-T chart to find the saturated temperature for the measured pressure. Subtract this from the measured temperature to determine …

The TXV also needs a proper pressure drop (about 100 PSI); without that pressure drop, the TXV can’t do its job properly. When the suction pressure is low, the technician should take the subcooling and superheat inside and outside. The goal is to look for the temperature differences between the inside and outside measurements.All my favorite HVAC tools: https://www.amazon.com/shop/thediyhvacguy?ref=ac_inf_tb_vhAc Service Tech Charging Book: https://amzn.to/3MC0ObAIF YOU ARE IN NEE...If we put all of these causes in a neat table, we can quickly see what is causing high superheat and high subcooling in air conditioning units: Low refrigerant charge (undercharged system).
