Which Fort Worth plumbers do ChatGPT, Gemini and Perplexity recommend?

By Lance Rankin, MBA | Tested November 10, 2026.

The short answer: three AI assistants, one question, three different lists. Together they named 16 plumbing companies. Only 3 were named by two assistants. None were named by all three.

The question we asked

"Who are the best plumbers in Fort Worth, Texas?"

We asked it once in each assistant, with web search turned on, the way a homeowner would.

Companies are listed in the order each assistant gave them.

Named by more than one assistant

  • ClearWater Plumbers: ChatGPT and Perplexity
  • Panther City Plumbing: ChatGPT and Perplexity
  • Schrader Plumbing: ChatGPT and Gemini

The other 13 companies were each named by only one assistant.

Where each assistant got its list

The assistants do not pick from memory. They search, read a few pages, and repeat what those pages say.

  • ChatGPT cited a Fort Worth plumbing market report, a review-ranking site (DIRT Trades), Expertise.com and a plumber directory (Pros411). It also said two of its picks were recommended by locals in Fort Worth Reddit threads.
  • Gemini mostly linked to the companies' own Fort Worth pages: Milestone, Baker Brothers, Berkeys and Rockwater. For Schrader Plumbing it linked to a Fort Worth Reddit thread.
  • Perplexity cited ten "best plumbers in Fort Worth" list pages, including ConsumerAffairs, BestProsInTown, Thumbtack, Yahoo Local, Expertise.com and ThreeBestRated.

What this means if you own a plumbing company

  1. Gemini favored big, long-established companies that have a page on their own site written just for Fort Worth. If your site has no page for the city you want, you are harder to name.
  2. ChatGPT read Reddit. What neighbors say about you in local threads now reaches people who never open Reddit.
  3. Perplexity repeated the list sites. Being on several of them is how a company gets named.
  4. Review count showed up again and again in the sources. The companies named twice have hundreds or thousands of Google reviews.
  5. A customer who asks ChatGPT and a customer who asks Gemini are being sent to different plumbers. You need to check all three.

How we ran this test

  • One question, asked once in each assistant, on November 10, 2026.
  • ChatGPT (GPT-5.4), Gemini (Flash) and Perplexity (Sonar Pro), each with live web search on.
  • AI answers change. Ask the same question tomorrow and some names will be different. This is one snapshot, not a ranking.
  • This is a report of what the assistants said. It is not Digital Regiment's opinion of any company, and nobody paid to be on this page.
