AI-Powered Field Repair Guide for Trade Technicians

mobile app real project •• multiple requests

HVAC, plumbing, and appliance repair technicians rely on memory and experience to diagnose equipment in the field. YC's Spring 2026 RFS identifies this as a high-willingness-to-pay vertical with low tech competition. The product: photograph the equipment, AI identifies the model and likely issue, provides step-by-step repair guidance. No specialized hardware needed, just a phone camera and a knowledge base.

builder note

The knowledge base is the moat, not the AI. Start with ONE equipment category (residential HVAC is highest-value) and build a structured diagnostic tree for the 20 most common units. Partner with experienced technicians to validate the repair steps. The photo recognition gets you the equipment model. The diagnostic tree gets you the repair. Charge $29-49/month per technician. Trade workers will pay for tools that make them faster.

Field service management tools handle scheduling and invoicing but not repair knowledge. Enterprise AI platforms (XOi, Augmentir) provide visual diagnostics but are priced for large companies. Independent technicians and small shops (1-10 trucks) have no affordable AI diagnostic tool. The gap is a mobile app that uses phone camera + equipment model database to provide step-by-step repair guidance without enterprise contracts.

XOi Technologies AI-powered field service platform with visual documentation. But enterprise-priced, requires integration with existing FSM software, and designed for large HVAC companies with 50+ technicians. Not accessible to independent contractors.
FieldPulse Field service management with scheduling, invoicing, and customer management. But no AI diagnostic capability. It manages the business side, not the repair knowledge side.
YouTube/Manufacturer Manuals Technicians currently search YouTube or download 200-page PDF manuals in the field. No structured diagnostic flow. Finding the right video for the right model and symptom takes longer than the repair itself.
Augmentir AI-powered connected worker platform for manufacturing. But focused on factory floor assembly, not field repair. Enterprise pricing and implementation. Not designed for independent HVAC or plumbing contractors.
