Junior HVAC technician struggles with diagnostic uncertainty, lacks confidence in troubleshooting refrigeration circuits due to inconsistent measurements and inadequate field training.

Workarounds Described

• takes manual pressure/temperature readings and tries to recall textbook values
• uses physical charging jacket and re-measures hoping for different results
• holds sensing bulb in hot water to test TXV operation manually

Implied Software Gaps

• Automated diagnostic guidance that cross-references real-time readings with fault patterns
• Historical data logging and trend analysis to show how system parameters change over time
• Mobile reference tool with interactive diagnostic trees for refrigeration cycles

DiagAssist HVAC

A mobile app that guides technicians through diagnostic steps, logs historical readings, and uses fault pattern recognition to suggest likely root causes. It replaces guesswork with a structured checklist and data-driven insights, boosting confidence and reducing callbacks.
