Integration resources
HVAC diagnostic resources for product teams
Technical guides for API buyers, agent builders, and service-platform integrators.
These resources complement the fault-code knowledge base. They cover abstention policy, benchmark methodology, build-vs-buy for diagnostic knowledge, and pilot outcomes — written for engineering and procurement, not field technicians.
Why HVAC agents must abstain when no exact OEM source exists
A field-service copilot that guesses on inverter boards destroys trust faster than it saves truck rolls. Abstention with audit trail is a product requirement, not a nice-to-have.
HVAC-Bench: protocol, scope, results, limits
HVAC-Bench is an internal protocol on sampled real fault codes (PAC, splits, boilers). Scores are scenario-level — not a blanket guarantee on every OEM code worldwide.
Build vs buy HVAC diagnostic knowledge
Building an OEM corpus in-house looks cheap until crawl drift, PDF versioning and liability land. Buying sourced lookup trades capex for metered API with citations.
First HVAC diagnostic API pilot — modest, verifiable results
We document a conservative pilot shape: ten high-volume codes, Developer key, weekly review of sourced vs abstain ratio — not a marketing case study with invented ROI.
