App Concept

DiagFlow HVAC

DiagFlow HVAC is a guided diagnostic app that helps technicians troubleshoot complex HVAC issues like intermittent faults, communicating systems, and legacy equipment. It uses a structured decision tree, symptom logging, and historical data to pinpoint root causes, reducing trial-and-error repairs. Features include step-by-step procedures, equipment-specific schematics, and remote support log sharing.

Key Features

Guided diagnostic workflows for common and complex HVAC issues
Symptom and test logging with timestamped history for intermittent faults
Access to equipment-specific schematics and troubleshooting tips (including legacy models)
Share diagnostic session logs with remote support or colleagues

Target Users: HVAC field technicians and installers who need structured troubleshooting help for complex systems, intermittent faults, or legacy equipment.

Revenue Model: Monthly subscription (SaaS) with tiered pricing: basic for individual technicians, pro for teams with shared log storage and priority support.
