The Most Recommended Plumbers in Chicago — Measured on ChatGPT
This Chicago edition started from 58 verified local plumbers. We then asked ChatGPT — 4 different ways, 4 checks in August 2026 — and wrote down every company it recommended.
31% — that's the share of Chicago's plumbers ChatGPT actually recommends (18 of 58). The most consistent of them: Rescue Plumbing, named in all 4 checks.
First Chicago Plumbing, Goode Plumbing and Roto-Rooter Plumbing & Water Cleanup and 1 more came next, named in 3 of 4 checks. 3 more companies came up less often and are listed below.
We don't crown a winner. ChatGPT gives a slightly different answer each time you ask, so the honest number is how many of the 4 checks named a company — not what place it came in. One mention out of 4 doesn't get published.
Among the 26 metros in the August 2026 run, Chicago ranks 24th by cohort size, with 58 plumbers benchmarked.
Only 18 of 58
Chicago-area plumbers we benchmarked ever get recommended by ChatGPT — that's just 31%. These are the companies it names:
Rankings are measured and cannot be purchased — sponsored blocks are labeled advertising and sit outside the ranked list.
Ask ChatGPT the same question twice and the answer can change. So we do not crown a number one. We publish how many of the 4 checks named each company. Companies named in more checks are the ones ChatGPT keeps coming back to. Companies named in only one check are not listed: a single mention does not repeat reliably.

Measured August 2026 · 4 homeowner-style questions · This list is measured, never sold — no company can pay onto it. Groups are set by how many checks named each company; inside a group the order is alphabetical, because the measurement doesn't separate them.
What we asked ChatGPT
Every check used one of these real homeowner questions, and every company ChatGPT named in response was recorded:
- “Who is the best plumber in Chicago, Illinois?”
- “I have a plumbing emergency in Chicago, Illinois. Which plumber should I call?”
- “What is the most recommended plumbing company in Chicago, Illinois?”
- “Who should I hire to replace a water heater in Chicago, Illinois?”
Inside the Chicago data

Common questions about the Chicago list
Does ChatGPT recommend many plumbers in Chicago?
Very few. Of the 58 Chicago-area companies we benchmarked in August 2026, only 18 were ever named across 4 checks — 31%. The rest never came up.
Who comes up most on the Chicago list?
Right now, Rescue Plumbing — recommended in every one of the 4 checks, and the only company at that level in Chicago.
Why don't you rank the Chicago companies 1, 2, 3?
A rank would be a made-up level of precision. ChatGPT answers slightly differently every time, and with 4 checks a company can only score 0 to 4. Several usually tie at the top, so we show the score and list tied names alphabetically rather than choosing between them.
Which questions produced the Chicago list?
We asked 4 homeowner-style questions, such as "Who is the best plumber in Chicago, Illinois?", and logged each company ChatGPT named in response. All the phrasings we used are shown above.
Is a spot on the Chicago board for sale?
Never. The board is measured, never sold: the only way on is to be named by ChatGPT in our checks. Money cannot buy a place on this list. Anything advertised alongside it is labeled as advertising.
Do Google reviews decide the Chicago list?
No — the grouping comes only from how often ChatGPT named each company in our checks. We show Google ratings for context: the Chicago board averages 4.8 stars across 14,841 reviews.
New to Chicago? These plumbers are just getting started.
Everything above this line was measured. The list on this page comes from asking AI assistants real questions and counting who they named — no one can buy their way onto it.
This section is different, and we want to be plain about it. The businesses below are brand new. They have not been measured, they have no rank and no score, and they are not part of the list above. They are here because they asked to be, we checked that they are real, and a business that opened last month has no way to show up in a ranking built on history. Nobody paid for a spot here — it is free, and it is not an endorsement.
Just opened a company in Chicago? You can be the first one here.
Tell us who you are and we'll add you to this section — free. It is not a ranking and it will never say you are ranked, because you are not: you are new. When we re-run the benchmark, a real spot on the list above is something you earn, not something we hand out.
