THE OTISOS DIAGNOSTIC ENGINE

A diagnostic engine built around how HVAC troubleshooting actually happens.

Start with the complaint. Inspect the system. Follow the evidence. OtisOS changes the workflow based on what the technician finds, keeps the important measurements together, and carries that evidence into recommendations and the final service report.

Equipment-aware by design.

Equipment intelligence and available technical/OEM sources can add equipment-specific context inside the same field workflow instead of separating diagnosis from equipment research.

PARTS & INVENTORY

Keep the truck and the job organized.

Parts information, supplier references, stock details, and usage history stay connected to field work.
