HVACDiagnostics & Troubleshooting4HighField Technician$ implied

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.

Workarounds Described

troubleshooting by blocking coils, removing charge, and adjusting TXV manually with no change

Implied Software Gaps

software that suggests less common failure modes and provides guided diagnostic steps when standard adjustments produce no change

App Concept

HVAC Diagnostic Pro

A mobile app that guides HVAC technicians through complex multi-circuit split system troubleshooting. Provides step-by-step diagnostic workflows, cross-references symptoms with rare failure modes, and suggests next tests based on real-time refrigerant readings.

Key Features

Step-by-step diagnostic flow for multi-circuit systems
Refrigerant chart with annotated normal/ranges
Common and rare fault library (e.g., stuck TXV, restrictions)
Data logging and comparison between circuits

Target Users: HVAC field technicians and service companies of any size

Revenue Model: Freemium with $19.99/mo pro tier for advanced diagnostics and data export
