AI HVAC Service Call Diagnostic Assistant
HVAC technicians diagnose issues through experience and trial-and-error. An AI diagnostic assistant that analyzes reported symptoms, system specs, and recent service history to suggest the most likely cause and fix would improve first-time fix rates and reduce callback frequency.
Problem Statement
An HVAC company sends a junior technician to diagnose a system not cooling. The tech checks refrigerant levels (normal), replaces a capacitor (not the issue), and leaves without fixing the problem. A callback is needed: $250 in wasted labor and travel. The actual issue was a dirty evaporator coil combined with a failing TXV valve — a pattern an experienced tech would recognize instantly. The company has 15 techs with varying experience levels and no way to share diagnostic knowledge systematically.
The Idea
An AI diagnostic assistant for HVAC technicians that analyzes reported symptoms, equipment model and age, recent service history, weather conditions, and common failure patterns to suggest the most likely root cause and recommended fix, improving first-time fix rates and reducing expensive callback visits.
Why Now
HVAC service call volume is growing. Technician shortage means less experienced techs handle complex diagnostics. First-time fix rate averages 70-75% in the industry. Each callback costs $150-300 in labor and travel. AI can now correlate symptom-equipment-history patterns to suggest diagnoses that would take experienced techs minutes but new techs hours.
Target User
HVAC service company owners and dispatch managers with 5-30 technicians
Target Market
Residential and commercial HVAC service companies in the US

Production AI Agent Evaluation and Regression Testing Framework
AI agent frameworks are proliferating but teams lack production-grade evaluation tools. A framework that tests agent behavior across scenarios, detects regressions in reasoning quality, and monitors production performance fills a critical gap.

Teams running local LLMs for agentic tasks face compounding failure rates: 90% per-step accuracy drops to 40% over five steps. A framework-agnostic guardrails layer that adds retry nudges, step enforcement, and VRAM-aware context management can bridge the gap between an 8B model and frontier APIs. Forge demonstrated this by taking Ministral 8B from 53% to 99.3% on multi-step workflows.
