Which plumbing companies does AI recommend in Austin?
We asked ChatGPT, Google Gemini, and Perplexity to recommend plumbing companies in Austin, TX — 6 hiring questions, 18 recorded answers, every one saved. They named 52 different businesses. These are the 20 that came up more than once.
Reliant Plumbing appeared most often, in 7 of 18 answers. 19 other businesses also appeared more than once.
Definition: openness measures how spread out the business names were in these 18 answers. Higher means more dispersed; lower means more concentrated. It is not market saturation, demand, or a quality score.
The 20 plumbing companies that came up more than once.
Ordered by how many of the 18 answers named them. This is not a ranking of quality and none of these are our clients — it is a record of who three assistants surfaced for Austin, TX on July 26, 2026. If you are one of the plumbing companies in this market and you are not on this list, that is the gap.

Even Reliant Plumbing does not win everything here. It was never named when we asked about whole-house repiping or best customer reviews. Those question types returned different names in our sample.
All three assistants agreed on 3 of them
Roto-Rooter Austin, Repipe Specialists (Austin), Cold Is On The Right Plumbing & Air were named by ChatGPT, Gemini, and Perplexity alike. Agreement across three systems that read different sources is the strongest position available in this sample. In Austin, that happened for 3 businesses.
Austin has more aging pipe than plumbers to work it.
The supply side here is comparatively thin: 369 employer plumbing, heating, and air-conditioning contractors in Travis County — one per 1,611 county housing units, under the code Census shares between the two trades. The housing stock is newer — median build year 1993 — but 466,428 city housing units generate service work regardless of vintage. The assistants named 52 plumbing businesses for Austin, only 20 of them repeatedly.
City figures: American Community Survey 2019-2023 5-year estimates, Austin city, Texas. County figures: County Business Patterns 2023, Travis County; establishment counts include only businesses with paid employees. The two boundaries are different sizes and are never divided into each other.
In Austin, the evidence sits on rotorooter.com.
None of this is a ranking you can buy into. The assistants named whoever was easiest to verify and safest to repeat, and in Austin they read rotorooter.com and reddit.com to decide it. Fixing that is the same work in every market, so it is written up once: what we build for plumbing companies.
For Austin, the source cited most was rotorooter.com.
All three assistants searched the web before answering and cited what they read. Across the Austin, TX answers they cited 180 sources. These are the ones they leaned on most — the pages actually deciding which plumbing companies get named here:
- rotorooter.com18
- reddit.com14
- reliantplumbing.com8
- abacusplumbing.com8
- siftpros.com6
- expertise.com6
- yelp.com6
- mrrooter.com6

- abchomeandcommercial.com4
- foxservice.com4
- angi.com4
- local.yahoo.com3
- serviceagent.ai3
- consumeraffairs.com3
- nextdoor.com2
Directories accounted for only 24.4% of the Austin citations; the rest came from businesses' own sites and local coverage. That is the better position to be in, because the page deciding the answer is one you control rather than one you have to petition to update.
Everything else the Austin scan turned up.
32 more were named exactly once
These came up in a single answer, from a single assistant, and never again across the other 17. That is the honest shape of Austin: a handful of businesses named repeatedly, and a long tail mentioned once by chance. Visibility that appears here and nowhere above will not survive the next re-run.

The assistants disagreed on 4 of 6 questions
Asked the identical question about Austin, 4 of 6 comparisons produced no shared business at all — three assistants, three separate shortlists. There is no single "AI answer" for this market to optimise against, which is why being named by one assistant tells a Austin owner very little about the other two.
Same questions, other markets.
The plumbing companies study puts all five cities side by side — which brands cross city lines, and which sources decide the answer trade-wide.
