HVACDiagnostics & Troubleshooting3MediumHVAC Technician$ implied

A newly installed HVAC system has abnormally high superheat and subcool readings, and despite replacing the liquid line and drier, the suspected faulty TXV from the factory is causing performance issues.

No accurate, systematic diagnostic tool to quickly verify if a brand-new TXV is defective out of the box, leading to trial-and-error part replacement and wasted time.

Implied Software Gaps

  • A diagnostic tool that can definitively test TXV performance without relying on manual interpretation of ambiguous pressure readings.
App Concept

TXV Check Pro

A smartphone-connected diagnostic tool and app that quickly tests TXV functionality on new installs. It analyzes refrigerant pressures, temperatures, and superheat/subcool data to confirm if a TXV is defective, saving technicians from unnecessary part swaps and callbacks.

Key Features
  • Bluetooth pressure and temperature sensor clamps
  • Instant pass/fail diagnosis of TXV operation
  • Records ambient and indoor conditions for context
  • Guided troubleshooting workflow with manufacturer specs
Target Users: HVAC technicians and service companies that install and commission new systems, especially those handling multiple brands of equipment.
Revenue Model: $299 for the sensor kit with app, then $19/mo subscription for cloud storage and advanced diagnostics
