The Most Recommended Plumbers in Chicago — Measured on Leading AI Assistants
This Chicago edition started from 55 verified local plumbers. We then asked leading AI assistants — 4 different ways, 4 checks in July 2026 — and wrote down every company it recommended.
36% — that's the share of Chicago's plumbers AI actually recommends (20 of 55). The most consistent of them: ABC Plumbing, Sewer, Heating, Cooling & Electric, named in all 4 checks.
First Chicago Plumbing and Rescue Plumbing came next, named in 3 of 4 checks. 5 more companies came up less often and are listed below.
We don't crown a winner. AI 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 July 2026 run, Chicago ranks 21st by cohort size, with 55 plumbers benchmarked.
Only 20 of 55
Chicago-area plumbers we benchmarked ever get recommended by AI — that's just 36%. 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 AI 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 AI keeps coming back to. Companies named in only one check are not listed: a single mention does not repeat reliably.

Common questions about the Chicago list
Does AI recommend many plumbers in Chicago?
Very few. Of the 55 Chicago-area companies we benchmarked in July 2026, only 20 were ever named across 4 checks — 36%. The rest never came up.
Who comes up most on the Chicago list?
Right now, ABC Plumbing, Sewer, Heating, Cooling & Electric — 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. AI 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 AI 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 AI 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 AI named each company in our checks. We show Google ratings for context: the Chicago board averages 4.8 stars across 57,908 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.
