Starting with commercial HVAC

Your best technician's
expertise, scaled to every tech

Dex is an AI copilot for the skilled trades. We codify your senior technicians' diagnostic and repair sequences into structured decision trees so junior techs can follow expert-level processes in the field — without constant escalation.

How it works

Senior expertise, delivered step-by-step to every technician on your team.

1

Capture expert workflows

We work with your senior techs to codify their diagnostic sequences, repair processes, and best practices into structured decision trees — paired with OEM documentation.

2

Guide techs in the field

Technicians follow step-by-step checklists and voice AI through inspections, measurements, and repairs. The app adapts the path based on what they find at each step.

3

Eliminate unnecessary escalations

Junior techs resolve complex issues using the same process a senior would — cutting callbacks, reducing rework, and freeing up your best people for the hardest jobs.

Built for the field

Every feature designed for technicians working on-site with complex equipment.

Structured Decision Trees

Your senior techs' diagnostic logic, turned into step-by-step checklists that adapt based on measurements and findings.

Voice AI Assistant

Hands-free interaction while on the job. Speak findings, get next steps — no need to stop and type.

OEM Documentation

Manufacturer specs and service manuals surfaced in context, right when the tech needs them.

Shop-Specific Practices

Not generic advice — your company's proven repair sequences and institutional knowledge, preserved and shared.

Inspection & Repair Guidance

Step-by-step through measurements, inspections, and repairs — the same path a 20-year veteran would take.

Fewer Callbacks & Rework

When every tech follows a proven process, first-time fix rates go up and costly return trips go down.
