How was this measured?

We asked Perplexity and Gemini the same 10 buyer questions through their APIs, three times each (October 2, 2026). A heating and air company counts as named when its name is written in the answer itself in at least 2 of the 3 runs; a link alone does not count. Every answer and citation is published as JSON.

Table 1 · Who gets named

The HVAC companies AI named

Small sample, read it as a snapshot: 10 questions, two AI tools, three runs each, on October 2, 2026. A lead of one or two checks is within the run-to-run noise. This says nothing about the quality of anyone's work, and a heating and air company missing here was simply not named in most runs of these answers.

What to do with it

If you run a heating and air company in Las Vegas

Your customers already ask these AI tools who to call. The answers above are what they get back. The HVAC companies named are the ones whose names show up on the sites the AI reads: the directories, review sites and best-of lists in Table 3, plus their own websites.

So start with the sites in Table 3. Make sure you are listed on the directories and review sites there, with your name written the same way everywhere. Find out who wrote the best-of lists and whether you belong on them. Then make your own site say plainly what you do, where you work and why people pick you, in the words a homeowner uses.

Do not judge from one answer. The names move from run to run, which is why every check here is three runs and a name only counts when it shows up in most of them.

See your own business

Are you one of the HVAC companies AI names?

This page covers the whole city. The AI Answer Check runs the same test on your own business: the questions your customers ask, three runs each on ChatGPT, Perplexity and Gemini, whether you are named, who is named instead, and the three fixes worth the most. I read every report before it goes out.

AI tools

Perplexity: Perplexity API, sonar model, live web search; cited URLs from the citations field. 30 answers.
Gemini: Google Vertex AI, gemini-2.5-flash with Google Search grounding; cited URLs from grounding chunks. 30 answers.
ChatGPT: Not measured in this edition: our OpenAI API credit was at $0 when the answers were collected, so no ChatGPT number is shown or estimated.

These are the APIs, not the consumer apps. Nobody was signed in and there was no system prompt: the question was the whole input. Each question went to each tool three times on October 2, 2026.

Who counts as named

A list of the businesses the answers recommend was built first by reading every answer. Then each answer was checked for each name in its text, with links and citation chips removed, so a cited link alone never counts. Spelling variants count as one name: curly or straight apostrophes, hyphen variants, and “&” or “and”. A name counts on a question and tool when it appears in at least 2 of the three runs. Directories, review sites and platforms are never ranked.

Sources

A citation is a URL the API itself returns as a source (Perplexity's citations list, Gemini's grounding sources resolved from Google's redirect links). Each site counts once per answer. Source types come from a written rulebook, not a person reading every page, so some pages land in the wrong group, mostly between company sites, blogs and lists.

Data

Every run, with its timestamp, tool, model, question, full answer text and citations, is in the JSON file for this page (60 of 60 answers stored in full). Questions with ChatGPT, and more cities, come in the next edition.
