Every answer is grounded in field-tested HVAC procedures — service sequences, wiring logic, charging steps, fault code interpretation. When it hits the edge of what it knows, it tells you.
Step-by-step guidance from the moment you arrive. Prentis handles the guesswork and sweats the diagnosis. You handle the fix and take the credit.
Snap the nameplate or tell Prentis the unit — Trane XR15, Carrier Infinity, any make or model. Upload a work order if you have one. Prentis fills in the rest. 30 seconds to start.
Pre-call · 30 secondsPrentis walks you through the exact diagnostic sequence for that unit — check the disconnect, verify power, measure the capacitor, pull amp draws. Step by step, hands-free. No typing. No searching. Just answers.
Voice-first · Hands-freePrentis organizes what you found: critical repairs, recommended work, and observations. Present to the customer, confirm what they approved, and get a timestamped close-out summary.
Customer-ready · DocumentedTell Prentis your experience level, your tools, and whether you run residential or commercial. Every diagnostic adjusts — a pre-apprentice gets step-by-step detail, a journeyman gets straight to the point. Your gear, your trade, your way.
Experience · Tools · TradeTested by veteran technicians, field service leaders, and HVAC educators on real equipment with real problems.
ChatGPT has never seen your unit, and YouTube has you stopping work to rewind a video instead of fixing the problem. Prentis identifies your equipment and talks you through it hands-free.
Prentis talks you through the diagnostic in real time, hands-free, using voice. Describe what you're seeing or point your camera at it, and it walks you through the next step out loud so your hands stay on the equipment.
Yes. Point your camera at a nameplate, wiring diagram, gauges, or fault code and Prentis uses what it sees — model, serial, pressures, error codes — as context for whatever you're working through.
You are always the licensed professional making the call. Prentis will stop you before you skip safety steps like capacitor discharge or EPA-608 verification, and when it hits the edge of what it knows, it tells you.
Yes — critical repairs, recommended work, observations, and a timestamped customer-ready summary. No more typing up notes in the truck.
