Trane Technologies manages millions of connected heating, ventilation, and air conditioning (HVAC) assets worldwide, but getting a single operational answer could mean cross-referencing multiple dashboards and drilling through menus for 20 minutes or more.

For organizations operating at this scale, that kind of friction slows operations, defers corrective action, and creates material business impact across the enterprise.

In 3–4 weeks, Trane’s engineering team built an AI-powered agentic solution on Amazon Bedrock AgentCore that reduced a 20-minute multi-screen diagnostic workflow to a 20-second natural language interaction.

This is based on Trane’s internal benchmarking with technicians over several weeks.

This represents a 60x improvement in time-to-insight, helping shift operations from reactive response to more proactive, data-driven optimization.

In this post, we describe the architectural approach and key design decisions behind the solution: Separating agent logic from tool execution.

Integrating real-time telemetry through a centralized tool gateway.

Tailoring responses to different personas.
