When we read through more than 64,000 Google reviews of nearly 900 US water treatment dealers this year, the “how did you find us” answers were what you'd expect: a previous dealer who stopped calling back, a plumber's referral, a realtor, a home show, Yelp. And in a couple of reviews from 2026, ChatGPT.
A couple of reviews isn't a trend. But homeowners don't write “I found you on ChatGPT” in a review unless it happened, and our team wanted to know what they saw when it did. So we asked.
On November 13, 2026, our team put the same question to ChatGPT, with web search on, for eight metros where hard water is a real sales conversation: Austin, San Antonio, Phoenix, Tampa, Jacksonville, Nashville, Raleigh and Columbus.
“What's the best water softener company in [city], [state]?”
We ran it through a ChatGPT search API set to a US location, so the results weren't shaped by our own history or logins, and we saved each full answer, the pages ChatGPT pulled, and the companies it named.
It was one answer per city, so read what follows as patterns rather than rankings. Ask the same question tomorrow and you'll get a somewhat different list. The patterns are what held across all eight.
Every answer led with four or five named local companies, each shown with a star rating, a review count, an address and a phone number. Then it added its own commentary: “my overall pick,” “worth considering for value-conscious buyers,” “good option for comparing established providers.”
That matters because the homeowner never sees a page of ten blue links. They see five names, a recommendation, and a phone number they can tap. If you're not in those five, you don't get a second look in that conversation.
The source that showed up most was Angi, which ChatGPT drew on in all eight cities. HomeAdvisor, the Better Business Bureau and Thumbtack showed up again and again too.
The second big source surprised us: local “best water softener companies” lists, often published by companies in other trades. In Austin, two of the pages ChatGPT read were ranked lists of water treatment companies written by an HVAC contractor and a plumbing company.
Dealers' own websites were rarely what it pulled from. That doesn't mean your site is irrelevant. It's where a homeowner goes after they've seen your name, and it's what Google ranks when someone searches from the next town over. We looked at that side separately in our research on city pages for water treatment dealers. But in these eight answers, being chosen happened mostly on other people's pages.
We expected ChatGPT to favor the dealers with the most reviews, and the big review counts were there: several companies with 800 to 1,200 reviews. But so were companies with 3, 9, 12 and 20 reviews, named in the same list.

Ratings were a different story. In three of the eight cities, a local location of a national water treatment brand appeared with a rating below 4 stars, and ChatGPT made the low rating part of the description rather than hiding it. In Tampa it explicitly noted the lower rating next to the name. A brand name didn't protect a location with a weak local reputation.
For an independent dealer, that cuts both ways. You don't need a thousand reviews to be named. But the reviews you do have are being read and summarized for the customer, including the bad ones.
This was the most useful thing in the test for anyone who sells water treatment. ChatGPT didn't stop at names. Most answers told the homeowner how to buy, and the advice was consistent:

Several answers also gave price ranges. The Austin answer, for example, put a basic whole-house softener at about $1,200–$2,000 installed and a softener with reverse osmosis at $3,500–$6,000 or more.
So a homeowner who arrives through ChatGPT has already been told to test, compare three quotes and watch for pressure. That's not a bad thing for a good dealer. It lines up closely with our review research, where the water test was the moment customers praised most, and the messages they rewarded were written test results, out-the-door pricing and “we'll tell you if you don't need it.” ChatGPT is coaching buyers to expect exactly what the best dealers already do.
Our reviews also show who wins once buyers compare. About 1 in 10 long 5-star reviews say the customer got several quotes, usually three and sometimes as many as 12, and the winner was often the dealer who explained the water best. Words like “explained” and “walked us through” show up in 14.8% of 5-star reviews and 5.1% of 1–2 star reviews.
In one city, the same company appeared twice in the top five, once with 378 reviews and once with 25, pulled from two different listings with two different addresses. ChatGPT treated them as separate businesses.
You can see how that happens. Old addresses, a second listing someone set up years ago, a different business name on Yelp than on Google. An AI assistant pulling from several directories can't always tell they're the same company, and a split listing splits your reviews.
None of this needs a new “AI strategy.” It's mostly the local basics, with a bit more weight on the places ChatGPT actually read.
Eight answers on one day is a snapshot. It doesn't tell you how many homeowners use ChatGPT to choose a dealer (judging by our review research, still a small share), how ChatGPT weighs one source against another, or whether getting named turns into booked water tests. Results also vary between runs, so a company named once won't necessarily be named the next time.
What it does tell you is where the answer comes from today: directory profiles, review ratings, other people's “best of” lists, and a buyer who has been told to expect a real test and a clear price. Those are things a dealer can work on.
Getting named in AI answers is part of our SEO and AEO work for water treatment dealers. If you'd like us to run this test for your market and see whether you're in the answer, get in touch. We'll show you what ChatGPT says about you before we talk about anything else.
Methodology: on Nov 13, 2026, one ChatGPT answer (web search on, US location, via DataForSEO's ChatGPT search API) per metro for the question above. Review figures come from Matyx's analysis of more than 64,000 Google reviews of nearly 900 US residential water treatment dealers.
"Ranking for water treatment terms is easy. Ranking for the ones that turn into installs is the job."
