HVACDiagnostics & Troubleshooting4HighField Technician$ implied

Technician struggles with diagnosing and repairing a 30-year-old HVAC system with multiple pre-existing modifications, compounded by lack of documentation and evidence of past improper repairs.

No software exists to help technicians document system history, log modifications, or guide proper repair procedures for old, non-standard field-modified equipment.

App to digitally document and share repair history of equipment to avoid repeating mistakes and guesswork

App Concept

HVAC Repair Historian Pro

A mobile app that lets technicians build a digital repair history for each HVAC system, including photos of modifications, serial numbers, and diagnostic logs. It uses AI to flag potential compatibility issues (like lineset sizing) and suggests best practices. Eliminates reliance on tribal knowledge and guesswork.

Key Features

Photo-based equipment timeline with before/after repair annotations
AI-powered lineset sizing calculator and oil return warning
Component serial number scanner with cross-reference to superseding parts
Digital log of past repairs by maintenance personnel or other techs

Target Users: HVAC technicians and service managers at small-to-midsize residential and commercial HVAC companies (5-50 techs) who deal with aging equipment and mixed maintenance history.

Revenue Model: $29/mo per technician subscription, $99/mo for service manager tier with team analytics and shared equipment history
