Homeowners in San Francisco don't call HVAC contractors the way they used to. They ask ChatGPT first. Then Perplexity. Then Claude or Gemini. By the time they pick up the phone, they've already made a mental shortlist of 2-3 names from AI summaries.
If your company isn't mentioned in those summaries, you're invisible to the most qualified leads in your market. This ranking exposes the gap.
The San Francisco HVAC Visibility Opportunity
We analyzed 137 HVAC contractors across San Francisco using a proprietary AI visibility audit. We queried ChatGPT, Perplexity, Claude, and Gemini with residential HVAC intent prompts and measured which contractors appeared, how often, and with what context. The results are stark:
- Median visibility score across all contractors: 32/100
- Top performer visibility score: 79/100
- Gap between top 3 and median: 47 points
That 47-point gap is not a detail problem. It's a market problem. It's worth tens of thousands in annual revenue per point for most HVAC businesses.
How We Ranked Them
Every contractor was scored on five dimensions:
- ChatGPT Mentions: How often the company appears in recommendations for common HVAC queries
- Perplexity Citations: Structured data present and accurate across Perplexity's knowledge graph
- Claude Recognition: Company and service descriptions cached in Claude's training knowledge
- Gemini Authority: Featured snippets, reviews, and business profile strength
- Information Consistency: Alignment across Google Business Profile, website schema, and third-party citations
Scoring is deterministic, not subjective. The same audit run produces the same score every time. Higher scores mean more AI mentions, cleaner data, and stronger authority signals across all four platforms.

What Separates the Top 3 From the Rest
The gap between rank 3 and rank 4 is 13 points. That's not random. It's structural.
The top 3 contractors share three traits: first, they own authoritative content about San Francisco HVAC systems and common problems. Second, they maintain consistent citations across Google Business Profile, schema.org markup, and trade directories. Third, they have service area pages that match local intent (not just one generic service page for the whole Bay Area).
The contractors at rank 4-10 do some of this. They have Google Business Profiles. Their websites exist. But they're missing one or two of the core visibility drivers. Missing schema means Claude doesn't cache them. No service area pages means Perplexity doesn't cite them for neighborhood-specific queries. Outdated business info across platforms means the consistency score tanks.
The median contractor (rank 32) checks none of these boxes. They have a website. That's it.
How Any San Francisco HVAC Contractor Can Climb
Three moves move the needle fastest:
Move 1: Own your service area schema. Create one page per neighborhood you serve: Sunset District, Richmond, SOMA, Mission, etc. Use LocalBusiness schema with GeoShape markup. Link them from your homepage. Perplexity will cite you for neighborhood searches within 30 days. This alone moves contractors +15-20 points.
Move 2: Rebuild your Google Business Profile data. Audit every field: business description (150 chars, include "HVAC" + "San Francisco"), service areas (list all neighborhoods), hours, phone, website URL. Make sure schema on your website homepage matches GBP exactly. Gemini scores consistency. Claude caches accuracy. This move is worth +8-12 points.
Move 3: Publish one seasonal authority piece per quarter. Spring maintenance checklist. Summer efficiency tips. Fall prep. Winter emergency response. 800-1200 words each. Post on your blog, link from homepage. ChatGPT pulls training data from blog content. One quarter of consistent publishing moves contractors +5-10 points.
Do all three and you'll likely gain 30-40 points within 60-90 days. Do one and you'll gain 10-15. Do none and you'll stay invisible while your competitors climb.
