Entry signal — what decides who wins here
One thing must be trueEntry turns on a single condition that can be named and tested before much is spent. Clear it and this becomes an execution question; fail it and no amount of operating skill helps.
Raise or borrow the entry ticket, or buy an operator who has already paid it. The barrier is money rather than permission, so it yields to a balance sheet — and an acquisition is usually cheaper than a start.
Measured, not forecast: the share of US establishments opening in one year that were still active later. It counts good operators and bad ones together, which is exactly why it is the honest answer to “what are the odds”. It is for the whole sector rather than this market, and the ten-year figure comes from an older cohort because no younger one has reached ten years.
This is not a probability of success, and it is not a verdict on you. No survival probability is published per market, and inventing one would be worse than saying so. What the bar reads is how much of the outcome sits inside an operator's control: green means the hurdles are ones a better operator clears, red means the binding constraint is capital, an asset or a permission rather than execution. Someone arriving with an advantage this screen did not assume can win a market shown in red.

The binding constraint — entry cost
The 'buy a boring business' thesis found this industry several years ago and repriced it: private-equity platforms and search funds now bid for the same HVAC and plumbing books, and multiples that were three to four times earnings are commonly five to eight. The buyer must also be the operator — technicians follow the owner, and licensing sits with individuals — so an absentee acquisition is the failure mode. The contractor software market at this code is a full study; this record is the operating business beneath it.
Trucks roll from one yard, so the market is a drive time — but acquisition multiples are set nationally by private equity platforms shopping in every city at once. A local business bought at a national price, which is the record's cut factor in one line.
US$82.24B of 2022 County Business Patterns payroll divided by 109,601 establishments. It is a wage bill, not revenue, and it fixes the scale of the typical firm: a handful of technicians, not a branch network.
Who you would be competing with
The operators already at scale here, and whoever is buying these businesses. In most of these industries the competition an entrant meets is local, so this is who sets the terms rather than a list of everyone in the trade.
Financials & market size — sourced
Figures that came from a filing, a results release or reputable reporting, each carrying its evidence tier.
Market size, derived
Built from the competitor set upward rather than quoted from a forecast. Published TAMs in these categories are frequently reverse-engineered from each other, so any published figure is checked against the vendor arithmetic rather than trusted on its own.
Disclosed revenue from 2 of 4 named vendors. The market is at least this large.
No vendor has both a disclosed revenue and a published share.
Only a revenue floor is known — the true market is larger by whatever the undisclosed vendors earn.

Evidence
Evidence. Comfort Systems USA's FY2025 revenue, its same-store and acquired split, its 50 operating locations, its 63.2%/36.8% new-build versus existing-building revenue mix and its 12.8% single-customer concentration were read in its 2025 Form 10-K; EMCOR's revenue was read in its own 10-K [A]. The business counts and size bands are Statistics Canada and US Census figures [A]. What these do not establish: both listed operators are US commercial and industrial mechanical contractors now heavily exposed to data-centre construction. They size the top of this NAICS code; they are not evidence about the price or economics of a Canadian residential plumbing-and-HVAC service book, which is what the record is about. The claim that multiples have moved from roughly 3–4× to 5–8× earnings is UNVERIFIED — no transaction document, broker series or platform disclosure was opened, and it is tiered accordingly in the figures. That licensing attaches to individuals and technicians follow the owner is analyst judgment, as is the cut factor. The contractor software sold into this code is screened separately.
