AI Visibility Score: Chicago HVAC Contractors

The audited Chicago HVAC business has five distinct phone numbers across its directory network: one on the website, a different number on Google Business Profile, another on Yelp and Apple Maps, a fourth on BBB, and a fifth on Yellow Pages. AI engines use NAP consistency as a primary entity resolution signal — when a business has 5 phone numbers in active circulation, AI systems cannot confidently attribute a single, authoritative identity to that business. The result is citation exclusion even when the business has strong review volume (1,214 Google reviews) and 70+ years of operation. This gap costs an estimated 10–14 points on the AI Visibility Score. Chicago HVAC contractors who do appear in AI results maintain a single phone number across all directory entries. The fix is not optional — it is prerequisite to AI citation in this market.

The audited business uses LocalBusiness schema — a valid but non-specific schema type. The Chicago HVAC contractors appearing most frequently in AI engine citations use the HVACBusiness schema type (a subtype of LocalBusiness defined in Schema.org). This matters because AI engines perform entity classification against structured data to determine whether a business is a relevant match for an HVAC-specific query. A generic LocalBusiness type forces the AI to infer industry from unstructured content; a specific HVACBusiness type makes the classification explicit and machine-readable. The Chicago audit identified this as a 2-point direct score gap in the B1 (website diagnostic) component, with downstream effects on AI engine confidence for industry-specific queries. The additional missing element: no FAQ schema, which is the primary citation surface for informational queries like "how much does AC replacement cost in Chicago" — the second-most common HVAC query type observed.

The audited business is present in 10 of the 52 citation sources VisiGap scans. The 42 missing sources include Bing Places, HomeAdvisor, Thumbtack, and Houzz — four tier-2 sources where Chicago HVAC competitors with AI citations hold active, verified listings. Each of these sources is indexed by AI training data and used as a citation signal. Bing Places is particularly consequential: it feeds Microsoft Copilot and supports Bing-indexed AI query responses, which are growing in share. The absence from HomeAdvisor and Thumbtack matters because both platforms publish structured contractor data (license numbers, service areas, review aggregates) that AI engines can extract and attribute to a specific entity. The 81% citation gap is the single largest score deficit in the audit — the B2 (citation sources) component accounts for 25 of 100 possible AI Visibility Score points.
