“I’ve been in HVAC/R 30 years — Navy, hospital mechanical, commercial work, still doing it as a service manager. I built this because everything out there was made by people who’ve never held a manifold gauge.”
Brian Ludlow — Founder · Navy Veteran · 30-Year Field Tech · Still Working Service
Every app for techs was built by
someone who’s never been on a rooftop.

Features That Actually
Help on a Job
Not dispatch software. Not invoicing. Tools a tech needs when standing in front of a broken unit.
Describe the symptom. The AI leads you through fault isolation — ranks suspects, asks targeted follow-up questions, and narrows to root cause the way a master tech would. Knows the unit’s full service history before you ask the first question.
R-454B, R-32, R-410A, R-22, R-404A, R-407C, R-448A, R-449A and more. A2L safety class and handling requirements included. Works completely offline — no signal needed on the roof.
Every reading, every part, every callback tied to that specific unit. Next time you’re on the same equipment you know exactly what’s been done and why it failed before. The health score tracks each unit over time.
Generated from what you actually fixed — not generic. Replaced a TXV? Verify bulb location, superheat stability, hunting range. Replaced a capacitor? Check amp draw, dual-run sections, system pressures. Every check is specific.
Upload your company PM form once. Photograph the unit nameplate and AI fills every equipment field automatically using vision. Talk-to-text for customer info. Download a completed PDF your customer can sign.
5-step survey plus AI video walkthrough analysis that flags obstacles before job day — overhead lines, tight hallways, crane staging issues. Generates full scope, equipment options with rebates, and pricing estimate.
