Which Austin plumbers does AI recommend? (Oct 2026 test)
When someone in Austin asks an AI assistant for an emergency plumber, which companies come up? We asked ChatGPT, Perplexity and Gemini the same 20 plumbing questions about Austin and counted every business each answer named: 61 different businesses in 60 answers, 12 of them named by all three engines.
How we tested
On October 29, 2026, as part of an anonymized sample report for an Austin emergency plumber (Sample A on our home page), we sent each question below to three AI engines through their official APIs, with web search switched on: ChatGPT (OpenAI gpt-4o-mini with web search), Perplexity (sonar) and Gemini (gemini-3.8-flash with Google Search grounding). 20 questions × 3 engines = 60 answers. We saved every answer word for word, counted every business each answer named, merged name variants of the same company, and recounted by hand on November 2, 2026.
Read this as a snapshot, not a ranking. Each question was asked once. AI answers change by date, wording and location, and the apps you use on your phone can answer differently from the APIs. Being named by an AI is not an endorsement from us, and we have not checked the ratings or claims the AIs repeated.
The 20 questions, exactly as sent (generated from a template, so a few read awkwardly):

How to get your plumbing business named by AI in Austin
No one can guarantee an AI will recommend you. These steps improve the public signals the answers above relied on.
- Complete your Google Business Profile. ChatGPT linked every business it named to a Google Maps listing. List emergency plumbing, water heaters, drains and leak repair as services, and mark 24/7 hours only if they are true.
- Make your own website answer the question. Gemini and Perplexity both cited plumbers’ own websites heavily. Have clear pages for emergency plumbing in Austin and the areas you serve.
- Be present where the AIs looked: Yelp, SiftPros and similar directories, with the same business name, address and phone everywhere.
- Publish the facts the AIs told homeowners to ask about: service-call and after-hours fees, arrival windows, written estimates, your Texas plumbing license number, and your service area.
- Earn reviews that mention the job and the area, such as a burst pipe or water heater repair in a specific Austin neighborhood.
- Re-check every month. Ask the questions your customers ask and note who is named. Answers change.
