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 named for Phoenix, AZ on July 26, 2026.

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 a stronger observed pattern than appearing in only one system. In Phoenix, that happened for 7 businesses.
One licensed shop per 1,154 homes: Phoenix plumbing is a crowded trade.

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.

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 optimize against, which is why being named by one assistant tells a Phoenix owner very little about the other two.
