Superheat is the sensible heat vapor absorbs after boiling into 100% dry gas inside the evaporator coil. Measuring superheat confirms whether the compressor is receiving purely dry vapor. Target: 8°F to 14°F at the outdoor service valve.

⚠️ Identified System Fault Symptoms
- Compressor liquid slugging risk
- Evaporator starvation causing high discharge heat
- Erratic cooling capacity under varying thermal loads
