Solution: A homeowner uploads their quote PDF and photos of their existing equipment. The AI: (1) Extracts equipment make, model, tonnage, SEER rating, refrigerant type; (2) Checks sizing logic against home square footage and zip code climate data; (3) Compares pricing to a benchmark database of comparable installs by zip code; (4) Flags red flags — high-pressure tactics, vague scope, missing items (ductwork inspection, Manual J load calc, refrigerant charge verification), suspicious 'lifetime warranties'; (5) Outputs a verdict score: 'Fair Deal,' 'Overpriced by ~$X,' or 'Major Red Flags Detected'; (6) Premium tier: connect to a vetted independent HVAC expert (not selling installs) for a 30-min video review at $99. ICP: Homeowners aged 30–70 who just got an HVAC replacement quote and are anxious about the price. Common scenario: a 'free' tune-up visit turns into a $15K–$25K replacement recommendation. The homeowner has no idea if the equipment is right-sized, if the price is reasonable for their region, or if they're being upsold. They post photos and quotes to r/hvacadvice asking 'am I being duped?' and wait days for crowdsourced answers from anonymous techs.

Neutrality is the entire moat — the platform makes money from homeowners, never from HVAC contractors. No referral fees, no lead sales, no advertising from HVAC brands. The benchmark pricing database (compiled from anonymous user submissions of actual closed deals) becomes more accurate over time and is impossible to replicate without scale.

“Similar to how TurboTax built a consumer-side product in a market dominated by tax preparers and CPAs — the established players were on the 'seller' side, and the consumer-side product became enormous because consumers had been underserved. This is TurboTax for HVAC quote review: a homeowner-paid product that doesn't depend on contractor referrals.”
