HVACDiagnostics & Troubleshooting3MediumStudent
A residential condenser will not turn on unless the contactor is manually activated, and the root cause cannot be identified despite verifying all major components.
Existing troubleshooting methods rely on manual component checks and schematics, but there's no guided diagnostic tool that can trace control wiring faults or suggest next steps when standard checks pass.

Implied Software Gaps
- A guided diagnostic tool that narrows down control circuit faults when component tests pass
App Concept
HVAC Diagnostic Navigator
An interactive diagnostic app that guides HVAC technicians and students through step-by-step troubleshooting trees. The user inputs symptoms and test results (e.g., contactor good, capacitor good), and the app suggests likely remaining causes (e.g., 24V control wire break, thermostat signal issue) with wiring diagrams and voltage measurement steps.
Key Features
- Step-by-step guided diagnostic flowchart based on symptom selection
- Integration with common HVAC models and schematics
- Voltage/continuity test result logging and interpretation
- Community feature to ask experts for edge cases
Target Users: HVAC students, apprentices, and field technicians at residential service companies or trade schools
Revenue Model: $9.99/month individual subscription or $99/year with premium wiring diagram library
