How The Master Group Wins by Staying an HVAC-R Specialist
The Master Group ranked fifth in HVACR on MDM's 2025 Top Distributors list. Here's how a Quebec-based specialist is buying its way into the U.S.

Part of Distributor Playbooks — strategy teardowns of every company on the 2025 MDM Top Distributors lists.
The Master Group placed fifth in the HVACR category of Modern Distribution Management's 2025 Top Distributors list, the trade publication's annual accounting of North America's largest wholesale distributors. The placement is notable less for the rank than for the direction of the money behind it: this is a Canadian distributor spending private-equity capital to buy American regional players, in a category where the traffic almost always runs the other way.
A specialist, not a diversified platform
The Master Group has been selling HVAC-R equipment since 1952, and it marked 70 years in business in 2022, according to Novacap's company profile, the Quebec private equity firm that has backed the company since 2014. The company has been named one of Canada's Best Managed Companies every year since 2010. It is headquartered in Boucherville, Quebec, and describes itself as Canada's largest privately held HVAC-R distributor.
An older ACHR News directory listing put the company at roughly 50 branches and four distribution centers. Novacap's current profile lists 68 branches and five distribution centers across Canada and the United States, with more than 1,300 employees. Whatever the exact pace, the trajectory is unmistakable: a company that already dominated its home market at "50 branches" scale has kept building well past it.
What it has not done is diversify. Most large North American distributors that reach this size eventually broaden into adjacent categories: plumbing, electrical, industrial MRO. The Master Group has stayed inside HVAC-R. That is the first strategic choice worth naming plainly: depth over breadth, in a decade when most of its scaled peers have chosen the opposite.
The acquisition engine points south
Since the mid-2020s the company's growth has run through acquisition, and every recent target has been American. It bought Distributor Corporation of New England (DCNE), a Carrier distributor serving eastern New England, an early step into the U.S. market, per MDM's coverage of the deal. It also picked up Fortress Group, a Waterloo-based HVAC-R wholesaler that had served southwestern Ontario since 1984, rounding out its home-country footprint before pushing further south.
Then in early 2023 it closed its second U.S. deal: Refrigeration Sales Corporation (RSC), an Ohio-based HVAC-R distributor founded in 1945, serving Ohio and western Pennsylvania. Houlihan Lokey's transaction record puts the closing at February 28, 2023. The announcement from Novacap frames it as explicit strategy, not opportunism: CEO Louis St-Laurent said RSC's "reputation for excellence, quality management, and customer service" made it "a natural choice," while president Neil McDougall pointed to RSC's own near-80-year run of "relentlessly serving customers." RSC's president, Rhonda Wight, described the deal as a "strategic partnership," not an exit.
That framing matters. This is the non-obvious pattern in the piece: in HVAC-R distribution, the well-worn consolidation story is a large U.S. platform crossing into Canada. The Master Group runs the trade in reverse. It is a Canadian specialist, funded by Canadian growth capital, buying regional American family businesses and asking their leadership to stay on. Reverse-direction, PE-funded, cross-border roll-ups inside a single product vertical are the exception in this industry, not the rule.
There is also a pattern in what it is buying. Fortress had run southwestern Ontario since 1984. RSC had run Ohio and western Pennsylvania since 1945. Both are the kind of multi-generational, founder-led regional wholesaler that eventually faces a succession question with no obvious internal answer. The Master Group's pitch to sellers like these is not "join our portfolio," it is "partnership," and RSC's own leadership used that exact word in the announcement. For a family business owner choosing between a financial-sponsor roll-up that will strip out the name and a strategic buyer that already runs the same category at scale, that framing is a real point of differentiation, not just a press-release nicety.
Why the model has stayed intact
Novacap's involvement since 2014 is worth sitting with. A decade-plus hold is long for growth equity, and it suggests the fund has been comfortable financing acquisitions rather than pushing toward a quick flip. That patience is arguably what has let The Master Group keep its single-vertical identity instead of getting folded into a multi-category platform the way many acquired regional distributors eventually are. The company gets growth capital without losing the thing that made it acquirable in the first place: deep, singular expertise in one category.
The trade-off nobody advertises
Staying single-vertical while acquiring across an international border is a coherent bet, but it is a bet with real edges. Depth in HVAC-R means the company competes for regional targets against fewer bidders than a diversified acquirer would, and it can integrate a new distributor without forcing it to also learn plumbing or electrical categories. That is the advantage of specialism.
The cost is a lower ceiling. Full-line rivals like Ferguson or Watsco can cross-sell an acquired branch's customer base into other categories the day the deal closes; The Master Group can only sell HVAC-R harder into that same base. It is also running this strategy on private-equity time. Novacap has held the position since 2014, which is a long hold for a growth-equity firm, and a decade-plus of ownership eventually resolves one of two ways: a larger sale or a public exit. Either would test whether a culture built on "since 1952" and "partnership" language survives new ownership.
None of that undercuts the model so far. Independent scale, disciplined category focus, and a willingness to buy the businesses everyone assumes should be bought by someone else, that combination has carried The Master Group from a regional Quebec wholesaler to a top-five North American HVACR distributor on MDM's own list.
Distribution rewards the companies that make branches, catalogs, and delivery trucks feel invisible to the contractor who just needs the part today. The Master Group's bet is that staying narrow is how you get good enough at that to keep buying the businesses that couldn't.
