HVAC technician cannot diagnose why a new split system's second circuit has 0° superheat and 3° subcooling, with standard troubleshooting not affecting the readings, indicating a likely stuck TXV or other issue.

no existing solution mentioned, but the technician is stuck on diagnostic logic; lacks a guided diagnostic tool for HVAC systems that accounts for rare failures like stuck-open TXV.
