How AI assistants choose who to recommend for water heater installation
We asked ChatGPT, Claude and Google AI Mode for water heater installation recommendations 233 times. Here is what they checked before naming a company, and what your page needs to say.
The short answer
AI assistants recommend a company for water heater installation when its own pages let them confirm that it serves the customer’s town or ZIP code, when it can schedule the job, that it does this exact job and how to reach a person. If any of that is missing, or contradicts the company’s other listings, the assistant has an easy reason to name someone else.

What people actually asked
We asked for water heater installation in three different ways. Here is each one, word for word, with how many of the 233 answers it produced between September 9 and October 14, 2026:
- “Water heater installation near me — I'm in St. Petersburg, FL 33713. Who do you recommend?”86 answers
- “Who should I call for water heater installation in Seminole, FL 33772?”75 answers
- “I'm looking to get water heater installation done in Pinellas Park, FL 33781 sometime this month. Who should I get quotes from?”72 answers, asked with five different timings: before the end of the month, sometime this month, in two weeks, in the next few weeks and next month
Together, the 233 answers covered eight towns in Pinellas County: Tarpon Springs, Clearwater, Dunedin, Largo, Palm Harbor, Pinellas Park, Seminole and St. Petersburg. Each town came up in 29 to 30 answers. By assistant: ChatGPT 104, Claude 81 and Google AI Mode 48.
Customers also call this “water heater replacement”, “new water heater”, “tankless water heater installation”, “tank water heater installation” or “hot water heater install”. Our research used set wordings; real customers phrase it more loosely, so use those words on the page too.
The question underneath all of them
“What is included in replacing my water heater?” Equipment type, installation work and removal of the old unit should be clear before comparing quotes. Answer it in the first lines of your water heater installation page, in the customer’s words, before asking them to call or book.
What your water heater installation page has to explain
Saying you offer water heater installation doesn’t answer that question. The detail customers and assistants are looking for is who confirms compatibility, related work and removal arrangements.
The proof that helps most is a completed installation with the equipment type and agreed inclusions. Describe your role and what was actually done, using real examples you have permission to show.
Finding a leak, repairing pipework and restoring an opened surface are different responsibilities. The page should also distinguish an urgent request from planned work such as a water-heater installation or a repipe.
What the assistants checked before recommending anyone
In July and August 2026 we recorded why assistants included or left out each business they considered, across eight trades. These are the checks that matter most for water heater installation, how often each one cost a business its place, and what the assistants said.
Where the assistants sent people
Each answer linked to the pages the assistant relied on. Of the 185 ChatGPT and Claude answers about water heater installation, this is how many linked at least once to each kind of site:
- A contractor’s own website: 95% (175 answers)
- A directory or review site such as Yelp, Angi or the BBB: 71% (131 answers)
- A manufacturer or home-improvement guide: 24% (44 answers)
- An official license lookup: 9% (17 answers)
A contractor’s own website was the page linked most often, so your site is usually what the customer is sent to read.
Google AI Mode works differently. In 73% of its 48 answers, the links opened Google’s own listing for a business rather than a website. There, your Google Business Profile is the page the customer sees, so it needs the same facts as your site.
Do you serve the customer’s town or ZIP code?
Assistants compared the service area with the exact place in the question. A page that names the town or lists the ZIP code settles it. “The Tampa Bay area and surrounding communities” leaves it open.
In our July–August study, assistants weighed whether the business clearly served the area asked about in 554 conversations, and it was the reason a business was left out in 350 of them.
Can you schedule the job when the customer needs it?
Assistants weighed timing more often than anything else in our study. For planned work they read what a company says about lead times and scheduling, and they noticed when that was vague or contradicted somewhere else.
In our July–August study, assistants weighed how quickly a company could come out in 657 conversations, and it was the reason a business was left out in 185 of them.
Some had enthusiastic recommendations, but not enough independently verifiable review, license, availability, and complaint-history data to rank them above the three selected companies.
Do you do this exact job?
Assistants looked for evidence that a company does the specific job asked about, not just the trade. A line in a services list is weaker evidence than a page that explains the job.
In our July–August study, assistants weighed whether the company specialized in the job asked about in 440 conversations, and it was the reason a business was left out in 184 of them.
Appeared mainly focused on drains, remodeling, HVAC, or large commercial work rather than household leak repair.
Can the customer reach a person?
Assistants favored a direct local number answered by a person, and passed over companies whose number they couldn’t confirm.
In our July–August study, assistants weighed whether there was a direct number a person answers in 290 conversations, and it was the reason a business was left out in 147 of them.
Who handles permits and inspections?
Assistants noted whether a contractor pulls the permit and handles the inspection, and counted it against those that offered to skip it.
A third-party permit aggregator reports substantial recent plumbing-permit activity and says its license was active when checked.
What will the job cost?
Published prices, flat fees and clear quote terms came up in hundreds of conversations. Assistants passed clear statements straight on to the customer.
In our July–August study, assistants weighed published prices, flat fees or a stated diagnostic charge in 366 conversations, and it was the reason a business was left out in 49 of them.
What happens if the fix doesn’t hold?
Warranty and labor cover came up as a deciding detail. A stated term (who provides it, how long it lasts, what it covers) says more than “satisfaction guaranteed”.
In our July–August study, assistants weighed warranty or labor cover in 150 conversations, and it was the reason a business was left out in 16 of them.
Select the lowest written total among companies whose license, identity and warranty terms are clear.
Other things the assistants weighed
- What do recent customers say? Review count and star rating came up constantly.
- Is your license current, and can it be checked? A license number on your own site is a claim.
- Can the assistant find and read your page? Assistants work from what their searches turn up and what they can read.
- Do your details match everywhere? Assistants compared the business name, phone, address and hours across the website, Google and directories.
- Who runs the business, and for how long? Local or family ownership and years in business came up in hundreds of conversations but seldom decided the answer on their own.
- What else vouches for you? BBB ratings, accreditation, awards and local mentions came up as supporting detail, rarely as the deciding reason.
- Can the customer pay over time? Financing came up occasionally, mostly on larger jobs.
- Can a technician actually take this job? An open calendar slot or a large fleet doesn’t show that someone can reach this address, for this problem, today.
- Will the customer reach you, or a middleman? Assistants told the company doing the work apart from referral networks and lead-generation sites, and preferred the company doing the work.
- Can you show the work? Project examples, inspection notes and before-and-after records helped assistants confirm a company does the job, provided they describe what was found and done.
Your water heater installation page checklist
Work through this list on the page itself. Each item answers one of the checks above.
- Use “water heater installation”, “water heater replacement” or “new water heater” in the page title, the main heading and the first paragraph.
- Answer “What is included in replacing my water heater?” in the first two sentences.
- Explain who confirms compatibility, related work and removal arrangements.
- Show a completed installation with the equipment type and agreed inclusions.
- List the towns and ZIP codes you actually serve, and tell a customer outside them how to check.
- Say how far ahead you are booking, how long the job takes and how the customer gets a confirmed date.
- Give the job its own explanation: what you do, which equipment or property types, and what you don’t take on.
- Put a working phone number at the top of the page and say who answers it, including after hours.
- Say who pulls the permit, who arranges the inspection and what paperwork the customer gets.
- Say what a quote includes, what could change it and when the customer approves extra work.
- State your labor warranty and any manufacturer cover, with its length and conditions.
Going further: let assistants see real openings
For planned work like water heater installation, a useful opening says whether it is for an assessment or the job itself, and whether the customer’s address is covered.
Merchant Context builds custom integrations with scheduling software so customers and AI assistants can read your current availability. Where your system records the job type, service area, duration and crew capacity, the integration can show those details with each opening, so an assistant can match it to the request instead of guessing.
We scope each connection to the software and data you actually have. A displayed opening is not a confirmed booking: the customer still confirms through your normal booking process, and the information is only useful while it is fresh.

Questions owners ask
Why isn’t my company recommended by AI for water heater installation?
Usually because the assistant couldn’t confirm something it needed from your pages or listings. In our study, businesses most often lost their place because the assistant couldn’t confirm that it serves the customer’s town or ZIP code, when it can schedule the job or that it does this exact job. Fix those on your water heater installation page first.
Which AI assistants did you test?
ChatGPT, Claude and Google AI Mode. Between September 9 and October 14, 2026, they answered 233 questions about water heater installation: ChatGPT 104, Claude 81, Google AI Mode 48.
Do I need a separate page for water heater installation?
If it is a real part of your business, we recommend one. It gives the assistant one place that answers the specific question, instead of a single line in a services list.
Will these changes guarantee a recommendation?
No. Nobody can promise that. These changes supply the facts assistants were looking for in our research. Whether a change moves recommendations for your business is something to measure after it goes live.
How we got these numbers
The questions and answer counts come from 233 answers we recorded from ChatGPT, Claude and Google AI Mode between September 9 and October 14, 2026, asking for water heater installation in eight towns in Pinellas County, Florida. They show what we tested, not how often real customers search.
The checks and the counts of businesses left out come from an earlier study of assistant conversations in July and August 2026, across eight trades, where we coded the reasons each assistant gave. A conversation can involve several reasons, so the counts overlap and are never added together. They show how often a reason came up, not how much it causes a recommendation, and they are not specific to this one service.
Link shares count an answer once for each kind of site it linked. Sites outside the named groups are counted as contractors’ own websites; a manual check of the 120 most-linked of them found almost all were. Google AI Mode’s links mostly carry Google’s internal ID for a business listing, so they are reported separately.
Quotes are the assistants’ own words. We only use quotes that don’t name a business.
