Diagnose with proof,
not guesses.
Precision diagnostic intelligence that helps trade technicians find faults faster, reduce callbacks, and document every diagnosis with confidence.
Techs deserve software that respects how they actually work.
For a decade, the trades have been sold cheap, bloated software that optimizes for the back office. The field technician is treated as an afterthought—a data entry node for dispatchers.
Determinari rejects this model. We build tools that make the technician faster, safer, and more accurate.
No AI guessing. No telemetry-for-its-own-sake. Just pure, deterministic engineering that works offline in a basement mechanical room as well as it does on a 5G connection.
Engineering-grade tools for the field.

Credibility through capability.
We don't need to invent fake testimonials. The software speaks for itself through rigorous adherence to industry physics and field constraints.
Glove-friendly UI
Hit targets the first time. Oversized touch areas, high-contrast states, and deliberate layout choices designed for actual fieldwork.
A2L Refrigerant Safety
Built-in intelligence for handling next-generation slightly flammable refrigerants. Safety protocols integrated at the calculation level.
Strict EPA Compliance
Deterministic tracking of recovered and charged refrigerants. Generate audit-ready EPA 608 documentation without a second thought.
100% Offline Capable
Mechanical rooms don't have 5G. Our calculation engines run locally on the device, syncing seamlessly only when connectivity returns.
Built for the ecosystem.
From the individual operating out of a single van, to regional service networks, to the manufacturers themselves.
For Individual Techs
Stop relying on rules of thumb. Bring deterministic precision to every diagnostic call, complete jobs faster, and elevate your personal craft.
For Shops
Standardize your service quality. Ensure every technician operates with the same baseline of excellence, while automating compliance tracking.
For OEMs
Embed our calculation engine directly into your hardware workflows. Partner with Determinari to deliver precision diagnostics natively.
