How ChatGPT, Gemini and Perplexity pick HVAC companies in Texas
Short answer: AI assistants recommend local HVAC companies they can find and verify across several sources: Google and Bing business profiles, directories like Yelp and BBB, reviews, and the company's own website. A company with the same name, address and phone everywhere, recent reviews on more than one platform and clear service and city pages is easier for them to recommend.
Why this matters for HVAC in Texas
When an AC stops working in July, homeowners want one name fast. More of them now ask an AI assistant "who should I call for AC repair in Frisco?" instead of scrolling through ads. The assistant typically names only a handful of companies, so being one of them matters more than ranking tenth on a search results page.
Where each assistant gets local data
The platforms don't publish exact rules. The table sums up what industry research reported in 2026.
| Assistant | Main sources reported | What to fix first |
|---|---|---|
| ChatGPT | Web search, with Bing's index as a major source; review and directory sites | Bing Places profile, directory listings, website clarity |
| Gemini / Google AI | Google Maps and Google Business Profile data | Google Business Profile: categories, services, photos, reviews |
| Perplexity | Web sources, with Yelp reported as a source for local businesses | Yelp profile and reviews |
The 2026 Local Search Ranking Factors survey by Whitespark added AI search visibility for the first time. One of its conclusions: for AI search, mentions of a business in directories and other sites (citations) work like links do in classic SEO. Review recency and volume, and how actively the owner manages the Google profile, also scored high.
A 9-point checklist for HVAC companies
- Same name, address and phone everywhere: website, Google, Bing, Apple, Yelp, BBB, Angi, Nextdoor. Merge or remove duplicate listings.
- One plain sentence on the homepage: who you are, what you do, which city, since when.
- Verifiable facts in text: Texas ACR license number (TDLR), year founded, hours, certifications.
- A page for each main service: AC repair, AC replacement, furnace repair, maintenance, with price ranges where you can.
- A page for each city you serve, with real local content, not a copy with the city name swapped.
- Reviews on more than one platform, ideally mentioning the service and city, with an owner reply to each.
- A FAQ written the way people talk to AI, with the direct answer in the first sentence.
- Bing Places and Apple Business Connect profiles, which many small contractors never set up.
- Schema.org markup (type HVACBusiness) with address, phone, hours and service area. Check it at validator.schema.org.
How to test your own company
- Ask ChatGPT, Gemini and Perplexity: "best AC repair in [your city] TX", "emergency AC repair [your city]", "how much does AC repair cost in [your city]".
- Ask each question two or three times. Answers vary between runs.
- Write down whether your company is named and who is named instead. Take screenshots.
- Fix the checklist items, then repeat the same questions 30 to 60 days later.
Nobody can guarantee what an AI assistant will say. What you can control is how easy your business is to find and verify.
