Entry signal — what decides who wins here
Structure decidesThe binding constraint is not executional. Being better than the incumbent does not, by itself, get you in — this one is cleared with capital, an asset, or a permission.
Come with the asset, or buy the business that owns it. Plant, fleet, land or quota decide this market before any operating skill does. Operators here are bought, not started.
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 — capital intensity
The pre-screen called this plant and pointed at the contractor records; the filings bear that out, but for a more specific reason than "factories are expensive". Demand is as good as it has ever been. AAON, the Oklahoma maker of semi-custom rooftop units and data-centre cooling — the nearest listed company to what a Canadian entrant would actually build — grew net sales 20.1% to US$1.44B in 2025 and ended the year with a record US$1.83B backlog, up 110.9% [A]. And in that same year its gross margin fell from 33.1% to 26.7% and net income fell from US$168.6M to US$107.6M, while it spent US$190.6M on capital expenditure — about 13% of sales — with another US$190.0M planned for 2026 [A]. That is the mechanism. In this industry an order book is converted into revenue only by floor space, coil lines, sheet-metal cells and test chambers that are bought and staffed before the units ship, and the margin is given up while the new plant learns to run. A company with a billion-dollar backlog absorbs that; an entrant has to fund the same sequence with no backlog to borrow against. Small makers do exist — 212 of Canada's 460 establishments have fewer than ten people — but the judgment here is that they are fabricating fans, hoods and one-off air handlers to a local engineer's drawing, which is a sheet-metal job shop, not an equipment line. The step from that to a catalogued, performance-rated product is the step that needs the capital, and a rated product must then still be taken on by a manufacturer's representative in each city who already carries a competing line. Plant software is screened separately.
Commercial HVAC and refrigeration equipment is specified by consulting engineers and sold through manufacturers' representatives city by city, but it is built in a handful of plants and shipped across the continent to common efficiency and safety standards. Ontario and Quebec hold 313 of Canada's 460 establishments and sell nationally and into the United States; the competitor on any given bid is a continental manufacturer, not the plant down the road.

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 5 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. Business counts are Statistics Canada (December 2023) and US County Business Patterns (2022). AAON's figures were read from its fourth-quarter and full-year 2025 results release as filed with the SEC on Form 8-K [A]; the 13% capex-to-sales ratio is arithmetic on those two figures. What they establish: one well-run mid-sized manufacturer, in the strongest demand it has seen, gave up six points of gross margin and spent about 13% of sales on plant to turn orders into shipments. What they do not establish: that every HVAC product line behaves this way — AAON is one company in a capacity build, and residential furnaces, commercial refrigeration cases and industrial fans, which share this code, were not researched. No Canadian listed anchor was found; the large Canadian makers are private. The description of what the under-ten-employee shops make, and of the representative channel, is analyst judgment from how the trade is organised, not a sourced statistic. The cut factor is analyst judgment. Added for the competitive field: Lennox's Building Climate Solutions segment revenue and segment profit, and the company's net capital expenditure, were read from the segment table in its fourth-quarter and full-year 2025 release as furnished to the SEC on Form 8-K, 28 January 2026 [A]; that release also records a change from LIFO to FIFO accounting effective the fourth quarter of 2025, with 2024 restated, so the comparison above is like for like within it. The Bosch transaction value, Johnson Controls' portion and its net cash proceeds were read from Johnson Controls' own completion announcement of 1 August 2025, furnished on Form 8-K [A]; that business is residential and light-commercial ducted HVAC plus the Hitachi joint venture, not the semi-custom commercial equipment screened here. Carrier, Trane, Daikin, Modine, Engineered Air and Price Industries are named without figures and were not researched.
