How this was measured: OrgScanner asked Anthropic Claude 3.5 Haiku, Google Gemini 3.5 Flash, OpenAI GPT-4o mini the 12 buyer-style questions a real customer would ask for “hvac in Pittsburgh”, and recorded which businesses each model named. A point-in-time check, not affiliated with William T. Leslie Heating & Air Conditioning. Generated 2026-06-17.

• No llms.txt found — AI has no machine-readable profile of William T. Leslie Heating & Air Conditioning to quote.
• Likely missing LocalBusiness JSON-LD schema — without it AI can’t reliably extract your services, hours, and service area.
• No GEO content answering the exact buyer questions (“best hvac in Pittsburgh”) that AI pulls from — the Fix Kit ships 5 ready templates.
