Give junior techs instant, expert-level guidance on diagnostics, error codes, and repair procedures — available 24/7, right from the field. Built for HVAC contractors and community college programs who want to close the skills gap faster.
ShieldTune's AI Mentor turns HVAC equipment manuals and service documentation into a conversational assistant that junior technicians can query in plain language — from any device, on any job site.
Junior techs can ask the AI Mentor questions in plain language and get instant, accurate answers about error codes, fault diagnostics, installation procedures, and maintenance protocols — grounded in real equipment manuals, available 24/7 from any device.
Community colleges can equip their HVAC programs with AI Mentor to accelerate student readiness. HVAC contractors can license seats for their field teams, getting junior techs up to speed faster and reducing costly callbacks and warranty repairs.
Contractors who want more than the standard knowledge base can have a private AI built from their own service bulletins, SOPs, and internal documentation — a truly company-specific assistant that reflects how their operation actually works.
ShieldTune's AI Mentor is powered by Retrieval-Augmented Generation (RAG) — a technique that connects a large language model directly to real HVAC equipment manuals, so every answer is grounded in actual documentation, not guesswork.
We ingest HVAC equipment manuals from leading manufacturers — error code tables, wiring diagrams, installation specs, and service procedures — along with building codes, environmental regulations, and other authoritative industry sources, all indexed into a searchable AI knowledge base.
A junior technician types a question — "What does E6 mean on a Mitsubishi mini-split?" — and the AI instantly retrieves the relevant documentation and returns a clear, accurate answer.
Responses are generated directly from the source manuals, not hallucinated. The system is designed to say "I don't know" when information isn't available, so techs always know when to escalate.
Contractors can extend the knowledge base with their own service bulletins, SOPs, and internal documents — creating a private AI that reflects how their specific operation works.
ShieldTune's AI Mentor is purpose-built for two audiences that are closely connected: community college HVAC programs and the contractors who hire their graduates.
Reduce the time it takes to get new techs running independently. AI Mentor gives your field crew real-time support — and contractors who want more can have a private AI built from their own service bulletins and internal documents.
Give students an always-available AI lab assistant that reinforces classroom instruction with real equipment knowledge. Students graduate more job-ready — familiar with actual diagnostic tools and multi-manufacturer equipment, not just textbooks.
