Which plumbing companies does AI recommend in Phoenix?
We asked ChatGPT, Google Gemini, and Perplexity to recommend plumbing companies in Phoenix, AZ — 6 hiring questions, 18 recorded answers, every one saved. They named 37 different businesses. These are the 19 that came up more than once.
Recommendations were more concentrated. Parker & Sons appeared in 10 of 18 answers.
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 19 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 Phoenix, AZ 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.
- Parker & Sons
- Roto-Rooter Plumbing & Drain Service (Phoenix)
- Benjamin Franklin Plumbing (Phoenix)
- George Brazil Plumbing & Electrical
- Wyman Plumbing & Mechanical LLC
- The Aussie Plumber
- Goettl Air Conditioning and Plumbing
- AZ Family Plumbing
- Lawson Family Plumbing
- Arizona Integrity Plumbing
- Repipe Specialists (Phoenix)
- Somers Plumbers
- Pink Plumbing & Sewer
- Robins Plumbing, Inc.
- Mr. Rooter Plumbing of Phoenix
- Ben Franklin Plumbing AZ
- Goettl Plumbing
- Ground Zero Plumbing, AC & Electrical
- Rite Way Heating, Cooling & Plumbing
Even Parker & Sons does not win everything here. It was never named when we asked about a failed water heater. Those question types returned different names in our sample.
All three assistants agreed on 7 of them
Parker & Sons, Roto-Rooter Plumbing & Drain Service (Phoenix), Benjamin Franklin Plumbing (Phoenix), Wyman Plumbing & Mechanical LLC, Arizona Integrity Plumbing, Repipe Specialists (Phoenix), Somers Plumbers 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 Phoenix, that happened for 7 businesses.
One licensed shop per 1,154 homes: Phoenix plumbing is a crowded trade.
Maricopa County packs 1,604 plumbing, heating, and air-conditioning contractors with payroll — Census shares one code between the trades — into 1,850,862 housing units, one employer shop per 1,154. In a field that dense, price-shopping is easy and the assistants' shortlist is a filter most of the market never passes: 37 plumbing businesses named for Phoenix, 19 of them more than once — competing over pipes as old as the 1984-median housing around them.
City figures: American Community Survey 2019-2023 5-year estimates, Phoenix city, Arizona. County figures: County Business Patterns 2023, Maricopa County; establishment counts include only businesses with paid employees. The two boundaries are different sizes and are never divided into each other.
In Phoenix, 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 Phoenix they read rotorooter.com and parkerandsons.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 Phoenix, the source cited most was rotorooter.com.
All three assistants searched the web before answering and cited what they read. Across the Phoenix, AZ answers they cited 166 sources. These are the ones they leaned on most — the pages actually deciding which plumbing companies get named here:
- rotorooter.com11
- parkerandsons.com11
- goettl.com10
- consumeraffairs.com7
- benfranklinplumbingaz.com5
- thumbtack.com5

- groundzeroplumbingac.com3
- ritewayac.com3
- deltahomeservices.com3
- serviceagent.ai3
- azcharged.com3
- georgebrazilplumbingelectrical.com2
Directories accounted for only 21.1% of the Phoenix 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 Phoenix scan turned up.
18 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 Phoenix: 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.

How many each assistant would name
- Google Gemini 23 plumbing companies named in Phoenix
- ChatGPT 19 plumbing companies named in Phoenix
- Perplexity 16 plumbing companies named in Phoenix
The assistants disagreed on 2 of 6 questions
Asked the identical question about Phoenix, 2 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 Phoenix 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.

Method. 6 questions × 3 assistants = 18 answers for Phoenix, AZ alone, collected July 26, 2026 from ChatGPT (gpt-5-mini), Google Gemini (gemini-flash-latest), Perplexity (sonar), with web search enabled because that is what a buyer's app does. Names were resolved across spelling variants first, so one company spelled three ways counts once. Assistants are non-deterministic; this is one dated run, not a standing ranking. The full methodology gives the prompts, the scoring formula, and what these numbers cannot support. Want it for your own business? The free AI visibility report runs it against your market.
