AutoHVAC uses advanced AI to analyze your residential new construction blueprints and generate complete HVAC designs with load calculations, duct layouts, and equipment specifications.
Our AI-powered workflow handles everything from load analysis to equipment sizing, delivering professional reports in minutes instead of hours.
While competitors struggle with single-brain AI that guesses, AutoHVAC deploys two specialized intelligence systems working in perfect harmony to achieve superhuman accuracy.
Deterministic Precision Engine
Reads PDF vectors, text blocks, and dimensions with mathematical precision
Parses window schedules, room boundaries, and energy notes instantly
Cross-validates scale, dimensions, and technical specifications
Speed: Processes structured data in milliseconds
AI Vision Intelligence
Analyzes elevation images for window overhangs and details
Reads handwritten notes and scanned architectural drawings
Confirms north arrows and building orientation from site plans
Intelligence: Fills gaps with human-like understanding
Traditional AI tools make random guesses when they can't read something, leading to wildly inaccurate load calculations
Our two specialized AI brains work together, each handling what they do best, ensuring nothing gets missed or guessed wrong
Every calculation backed by confidence scores and assumption logs. You know exactly what was found vs. what was assumed
See how our revolutionary two-brain system turns your blueprints into perfect load calculations in 60 seconds.

No way! Generic AI like ChatGPT would be completely unsuitable for professional HVAC work. AutoHVAC uses our proprietary Two-Brain System: Brain A (Deterministic Precision Engine) reads PDF vectors and technical data with mathematical precision, while Brain B (AI Vision Intelligence) handles complex visual analysis. This dual-brain approach ensures every calculation is backed by confidence scores and assumption logs - no guessing, no hallucination, just professional-grade accuracy that meets ACCA standards.
