How it works

Three steps. Start to close-out.

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.

01

Start your call

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.

02

Walk through it together

Prentis 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-free
03

Close it out

Prentis 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 · Documented

Adapts to your experience

Tell 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.

Frequently Asked Questions

Just Answers.

How is Prentis different from using ChatGPT or YouTube?

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.

How does Prentis compare to Bluon or MeasureQuick?

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.

Can Prentis read a nameplate or see my gauges from a photo?

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.

What if Prentis gets it wrong?

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.

Can Prentis write up the service call?

Yes — critical repairs, recommended work, observations, and a timestamped customer-ready summary. No more typing up notes in the truck.
