Which plumbing companies does AI recommend in Las Vegas?

The market behind the answers

One licensed shop per 1,483 homes: Las Vegas plumbing is a crowded trade.

Clark County packs 631 plumbing, heating, and air-conditioning contractors with payroll — Census shares one code between the trades — into 935,960 housing units, one employer shop per 1,483. In a field that dense, price-shopping is easy and the assistants' shortlist is a filter most of the market never passes: 42 plumbing businesses named for Las Vegas, 15 of them more than once.

City figures: American Community Survey 2019-2023 5-year estimates, Las Vegas city, Nevada. County figures: County Business Patterns 2023, Clark County; establishment counts include only businesses with paid employees. The two boundaries are different sizes and are never divided into each other.

What we would do about it

In Las Vegas, 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 Las Vegas they read rotorooter.com and pureplumbinglv.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.

Where the answers came from

For Las Vegas, the source cited most was rotorooter.com.

All three assistants searched the web before answering and cited what they read. Across the Las Vegas, NV answers they cited 179 sources. These are the ones they leaned on most — the pages actually deciding which plumbing companies get named here:

• rotorooter.com12
• pureplumbinglv.com12
• reddit.com9
• goettl.com7
• angi.com6
• activeplumbinginc.com6
• vegasvalleyplumbing.com4
• forbes.com4
• consumeraffairs.com4
• mrrooter.com4
• las-vegas.repipe.com4
• expertise.com3
• nvcontractorsboard.com3
• homeguide.com3
• rankmetop.net3
• precisionplumbinglv.com3
• larkinplumbingservice.com3
• sincityplumbing.com3
• nrs.vegas3
• idealservices.com3

Directories accounted for only 21.2% of the Las Vegas 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.

The full record

Everything else the Las Vegas scan turned up.

27 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 Las Vegas: 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 1 of 6 questions

Asked the identical question about Las Vegas, 1 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 Las Vegas owner very little about the other two.

5.6% of answers named nobody at all

In 1 of 18 answers the assistant declined to recommend anyone and pointed the buyer at a directory or a list of things to check instead. Those are answers where no Las Vegas business won anything.

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.
