Valuing an HVAC or Trades Business for Sale in Canada

Canada's HVAC and mechanical trades sector is in the middle of a sustained buying wave, and the forces driving it are structural rather than cyclical. They are not going to ease off on their own. Millions of systems installed during the building boom of the 2000s are reaching the end of their working life at the same time that refrigerant phase-outs and tightening efficiency standards are forcing replacement cycles to move faster, and heat-pump electrification programs are stacking a policy tailwind on top of all of it. Owners who assume they can wait for a better moment to sell, or who plan to figure out valuation once a buyer actually calls, are negotiating from a position they did not choose. The buyers on the other side of the table have closed dozens of deals this year alone and know what they are willing to pay and why, putting an unprepared seller at an immediate disadvantage.

Private equity-backed platforms are leading the charge, and they move with the discipline of professional acquirers rather than the patience of a retiring owner's hoped-for successor. Apex Service Partners closed roughly 60 add-on acquisitions in 2025 across a large portfolio of brands generating substantial revenue, Wrench Group runs numerous brands across many markets, and Sila Services was recapitalized at a significant valuation in early 2025. None of these are passive investors waiting for the right shop to come along. They are running acquisition programs with set criteria, and an owner who walks into that conversation without understanding how these buyers actually price a business is negotiating blind.

The Three Earnings Metrics Canadian Buyers Use

Canadian buyers apply three distinct earnings metrics depending on business size, and conflating them produces a number that is either misleading or useless as a negotiating anchor. Using the wrong one, or blending them without realizing it, produces a figure that either misleads the owner about what the business is worth or carries no weight at all once a buyer pushes back.

Seller's Discretionary Earnings, or SDE, is the standard for owner-operated shops. It is calculated by adding the owner's salary, benefits, and one-time expenses back to net profit, and it exists because a smaller business often runs its owner's personal compensation and incidental costs through the income statement in ways that obscure the business's real earning power. For a shop where the owner is still the one answering emergency calls, SDE is the number that matters.

EBITDA multiples apply at scale, with the Canadian-specific framework running in three tiers.

It says nothing about profitability or cost structure, and anchoring a negotiation to it is a mistake that costs real money at the table. Canadian sellers tend to clear a meaningfully lower multiple than U.S. equivalents at the mid-market tier, though that gap narrows at the platform tier, and solid deal preparation can close part of it.

What moves the multiple, and by how much

Once the right earnings metric is on the table, the next question is what actually pushes that multiple up or down, and the single biggest lever by far is recurring revenue. Two HVAC businesses can post identical EBITDA and still receive offers that differ by two full turns of the multiple, depending on how much of that revenue is locked into contracts rather than earned call by call. A business with a significant share of its EBITDA tied to maintenance agreements can draw a materially higher offer than an otherwise identical business with no recurring base at all. Why does a maintenance contract carry that much weight compared to, say, a strong word-of-mouth reputation or a full project pipeline? Because a signed agreement gives a buyer something to underwrite with confidence: predictable cash flow a bank or investment committee can model, service and maintenance margins that run well above installation work, and a pipeline of customers whose systems will eventually need replacing through the same company that has serviced them for years.

Commercial HVAC work tends to command higher multiples than residential, since contract values run larger and customer relationships stretch longer, and a contractor with genuine building-automation-systems or controls competency can add another 0.5 to 1.0 turn on top of that. Three to five years of financial history showing steady annual revenue growth gives a buyer's underwriting team the confidence to move, and a defined geographic footprint with real truck density in a given market matters to PE platforms whose entire strategy depends on building density across a region. On the other side of the ledger, a business that only functions when the owner is physically present typically loses a meaningful share of its value, because owner dependency is one of the first red flags that PE diligence uncovers.

The buyer pool's effect on the multiple

Owners who compare notes about sale prices often run into numbers that seem to contradict each other, and the confusion usually comes down to one overlooked fact: the multiple quoted by a main-street business broker and the multiple quoted by a private equity platform come from two entirely different buyer pools, not from two different opinions about the same market. Which pool a given business can actually reach depends on its own characteristics, not on which number the owner would prefer to believe.

BizBuySell's five-year average from 2021 through 2025 is modest, well under double SDE, and that figure reflects what smaller, owner-operated businesses actually clear in the main-street market. It blends both listing data and sold data, and listing-based multiples tend to run higher than what actually closes. A sub-threshold SDE owner-operated shop in Nova Scotia is not going to attract the largest PE platforms, a structural fact about where that business sits relative to what those buyers are built to acquire, not a reflection of its quality.

PE platforms pay premium multiples for businesses that fit a specific buy-box: strong EBITDA, meaningful recurring revenue, multiple locations, and a management team capable of running operations without the founder in the room. Typical deal sizes for these platforms are in the mid-market range, and once a letter of intent is signed, closings tend to happen within weeks. One might ask what separates a business that can reach that pool from one that cannot. Consider a residential contractor with hundreds of active maintenance agreements and a second-generation manager running daily operations independently of the founder. That business can legitimately compete for PE attention, and the gap between running a sale process that actually reaches those buyers and only reaching local owner-operators can be worth several turns of the multiple. Neither pool is the wrong one to sell into. The task for an owner is figuring out, honestly, which pool their business currently qualifies for, and what it would take to move into the other one before going to market. That is the argument for running a properly structured sale process through advisors who have relationships across both the main-street and platform sides of the market, rather than defaulting to whichever buyer happens to call first.

Canada-specific risks that buyers price into the offer, and that owners rarely see coming

Three risks specific to Canadian HVAC transactions recur in diligence, and all three routinely compress offers or kill deals outright when they surface late: licensing transferability, OEM dealer agreement change-of-control clauses, and the effect of the labour shortage on how EBITDA gets normalized.

Licensing does not transfer automatically between an old owner and a new one, and the structure of the deal determines how quickly it can. A share sale requires TSSA notification within a defined short window, while an asset sale requires fresh registration and a new link to the technician's certificate of qualification. In Quebec, transferring an RBQ licence in an asset sale can take up to 60 days, and current processing delays can stretch that further. In BC, an asset-sale licence transfer takes several weeks. None of these timelines are long by themselves, but a buyer who discovers this complexity late in diligence is going to either reprice the deal or walk away from it, and that is a risk an owner can neutralize months in advance simply by confirming which path the deal will take and starting the paperwork early.

OEM dealer agreements carry a similar trap. Carrier, Lennox, Trane, Daikin, Goodman, and Mitsubishi all write change-of-control clauses into their dealer agreements that give the manufacturer consent rights over a sale, and resolving that consent before closing, not after, is what keeps the deal from stalling at the finish line.

The labour shortage adds a third layer of risk that affects how buyers read the trailing financials. Canada's shortage of skilled HVAC technicians ran to thousands of unfilled positions in 2025, and in some cases pushed commercial retrofit schedules out by as much as six weeks. Alberta and Saskatchewan feel this acutely, since oil and gas trades in those provinces pay substantially more than HVAC employers can match, pulling technicians away from the field. Buyers respond by scrutinizing technician headcount, the depth of Red Seal certification across the crew, and how long foremen have stayed with the company, with five or more years of documented foreman tenure treated as a genuine value driver, alongside keeping any single customer's share of revenue low. Wage inflation through 2023 and 2024 compressed HVAC margins across the industry, and acquirers now normalize EBITDA to account for that shock, which changes how the trailing earnings figure gets presented in a deal. Working capital adds its own Canada-specific wrinkle: inventory carried per service vehicle runs to a significant cost, refrigerant inventory carries an HFC excise tax burden, and receivables can clear in days for a residential job paid at point of sale but stretch to many weeks for commercial work governed by CCDC contracts with a statutory holdback. None of these risks are disqualifying on their own. What they share is that a seller who understands them and addresses them before going to market keeps the price that a seller who gets surprised by them in week six of diligence typically has to give back.

Canadian tax structuring and after-tax sale proceeds

Everything discussed so far determines the size of the offer. None of it determines how much of that offer the owner actually keeps, and for a Canadian HVAC business, the tax structure of the sale can swing the after-tax outcome by more than a full turn of EBITDA multiple would. The tools that make that difference are specific to Canada and, in some cases, time-sensitive.

The Lifetime Capital Gains Exemption stands as the single most valuable tax planning tool available to an owner at exit. As of 2026, it allows each eligible Canadian individual to shelter up to approximately $1,275,000 of capital gains from income tax when selling shares of a qualifying small business corporation, and the exemption applies per taxpayer. For a shareholder paying tax at the top combined federal and Ontario marginal rate, sheltering the full amount saves a genuinely large sum, and spouses who each hold independently qualifying shares can combine their exemptions for an even larger shelter.

Whether the LCGE applies at all comes down to one structural decision made long before closing: whether the transaction is structured as a share sale or an asset sale. In an asset sale, the corporation itself is the seller, not the individual owner, so the LCGE cannot be applied at all. Buyers, for their own tax reasons tied to asset step-up, often prefer to structure deals as asset sales, so the negotiation over deal structure is not a technicality tucked into the lawyers' side of the file but a question of how much money changes hands between buyer and seller once the Canada Revenue Agency has taken its share.

One piece of recent policy news changes the calculus for the better. The federal government's proposed increase to the capital gains inclusion rate, which had created real uncertainty in planning conversations through 2024, was formally cancelled on March 21, 2025 by Prime Minister Carney, and the inclusion rate remains at its long-standing level. For an owner weighing when to sell and how to structure the transaction, that cancellation removes a source of risk that had been hanging over every exit conversation in the sector, and it means the planning tools described here rest on firmer ground than they did a year earlier.
