Solution: Mobile app: homeowner takes 8–12 photos of their HVAC system following a guided walkthrough. The AI: (1) Identifies obvious defects (line set insulation gaps, missing drain trap, condenser not level, return plenum too small for tonnage); (2) Cross-references the equipment model number with manufacturer install specs; (3) Generates a defect report ranked by severity (immediate safety issue, warranty-affecting, performance-degrading, cosmetic); (4) Provides exact language and citations to use when contacting the contractor for warranty correction; (5) Premium tier: optional 30-minute video review with an independent HVAC professional for high-severity findings. ICP: Two main personas: (1) New construction home buyers who closed in the last 12 months and want to verify their builder-installed HVAC system before the 1-year warranty expires; (2) Homeowners who just paid $10K–$25K for a replacement install and want to verify the contractor didn't cut corners. Both audiences are frustrated by installers who don't know basic specs — like that a 4-ton blower needs a 20x25 return plenum.

The HVAC-specific defect database is the unique technical asset — knowing that a 4-ton blower needs a 20x25 return plenum, that minisplit flares are the number 1 failure point, that drain lines need a P-trap. This domain knowledge requires HVAC expertise that generic AI inspection tools lack. The warranty-period framing creates urgency — homeowners with 11 months left on a builder warranty have a clear action window.

“Similar to how HouseCanary and Truebill emerged to give consumers visibility into expert decisions previously hidden by professionals. This product gives homeowners visibility into HVAC install quality that the industry has structurally hidden from them.”
