The compounding consolidation: how private equity is rolling up HVAC

Private equity did not discover HVAC by accident. It found a category that checks every box an institutional underwriter looks for: recession-resistant demand, recurring service revenue, an aging installed base that forces replacement regardless of the economy, and a market so fragmented that no single operator holds meaningful national share. That combination is why the deal count keeps climbing even as the multiples paid for it start to normalize — and why the shape of the HVAC industry your dealers, reps, and OEM partners operate in looks structurally different than it did five years ago.

This piece pulls together the two most-cited data sources in the space right now — McKinsey & Company's February 2026 home services research and Capstone Partners' HVAC Services and Equipment M&A updates — along with platform-level tracking from CT Acquisitions and S&P Global Market Intelligence, to lay out where the compounding is actually happening, where it's slowing, and what it means for anyone operating inside the OEM-to-dealer value chain.

§1Why PE Underwrites HVAC Like Infrastructure

Not a hot sector bet — a durability bet.

McKinsey's framing is the one worth sitting with: home services broadly is roughly a $700 billion annual market in the US, projected to reach $802 billion by 2030. HVAC sits in the most attractive quadrant of that market — "critical and frequent" — alongside pest control and security. Homeowners defer a kitchen remodel. They do not defer a failed furnace in January or a dead condenser in a July heat wave. That non-discretionary demand profile is precisely what makes a service category financeable: lenders and sponsors can underwrite cash flow through a downturn.

The second half of the McKinsey thesis is fragmentation. Independents and local operators still hold roughly 80%+ of home services markets in the critical-and-rare categories, and around half of the critical-and-frequent segment where HVAC sits. No platform has consolidated HVAC the way national players have rolled up other trades. That gap between "essential, recession-resistant demand" and "almost entirely unconsolidated ownership" is the entire private equity thesis in one sentence — and it's why the roll-up math still works even as multiples come down from their 2021–2023 peak.

"The fragmented nature of the sector has allowed sponsors to build out platform service lines and subsequently roll up small, local operators that offer well-established regional coverage, institutional relationships, and exposure to unique end markets."

§2The Deal Volume Is Compounding, Not Cooling

Fewer platform formations, far more add-ons — the roll-up machine shifting into its next gear.

Capstone's July 2026 update puts total HVAC services deal volume at 92 announced or completed transactions year-to-date — down slightly year-over-year in raw count, but the composition tells the real story. Sponsor-backed activity actually rose to 47 transactions, with private equity add-ons alone accounting for 38 deals, up from 36 in the same period last year. Platform creations — brand-new PE entries into the space — dropped from 10 to 9, which is exactly what you'd expect in a maturing roll-up cycle: the land grab for new platforms slows down while the existing platforms accelerate their buy-and-build cadence.

Zoom out to the platform level and the acceleration is even sharper. S&P Global Market Intelligence reported that global PE add-on transactions targeting HVAC service providers rose 88% year-over-year through mid-2025, with sponsors and platforms combining for 39 of 77 tracked HVAC deals in that window. CT Acquisitions' independent platform tracker counted at least 18 verified, citation-anchored US HVAC roll-up platforms actively acquiring in 2024–2026, backed by sponsors ranging from Alpine Investors and Blackstone to Goldman Sachs Alternatives and Bain Capital.

Capital is recycling between sponsors, not exiting the category

The clearest evidence that institutional conviction is deepening, not plateauing, is what's happening at the platform-sale level. These aren't founders selling out of PE ownership back to strategics — they're PE-to-PE hand-offs at escalating valuations:

§3Multiples Are Normalizing — Which Is Different From Cooling

The 2021–2023 bull-market peak is gone. The buyer pool that replaced it is bigger.

Here's the nuance that a lot of LinkedIn commentary on "PE eating HVAC" misses: valuations have come down from the frothy 2021–2023 period, but that's a structural reset toward smaller, more disciplined bolt-ons — not a loss of appetite. Capstone's data shows HVAC services multiples settling at an average of 2.0x EV/Revenue and 9.5x EV/EBITDA between 2024 and YTD 2026, down from 2.3x and 13.3x in 2021–2023. Broader sector-wide HVAC valuations followed the same pattern, dropping to 11.4x EV/EBITDA from 13.4x.

Services multiples compressed from the 2021–2023 peak as buyers shifted toward smaller bolt-ons. Equipment multiples moved the opposite direction — up nearly two full turns in a single year — driven almost entirely by data center and liquid-cooling demand.

That divergence matters. On the services side, the market is pricing in more bolt-ons at lower per-deal multiples — good news if you're a $1–5M EBITDA dealer thinking about a sale, because it means more buyers are chasing you, even if the headline multiple looks smaller than the platform-level deals in the trade press. On the equipment side, multiples are expanding because manufacturers and component makers with exposure to data center thermal management are commanding a real premium — Ecolab's $4.8 billion acquisition of CoolIT Systems in March 2026 priced at roughly 29x NTM EBITDA, an outlier that shows just how much AI infrastructure demand is distorting equipment-side valuations.

Below the platform tier, CT Acquisitions' compiled 2026 ranges give the clearest picture of what an actual owner sees at the negotiating table:

§4Data Centers Are Underwriting the Equipment Cycle

The one growth vector both McKinsey and Capstone independently converge on.

If there's a single variable that explains why HVAC equipment deal activity reversed course in 2026 after a soft 2025, it's compute infrastructure. McKinsey's own operations research pegs the global data center cooling market at $40–45 billion by 2030, with liquid cooling alone worth $15–20 billion of that. Capstone's equipment-side reporting shows US data center electrical consumption roughly doubling from 183 terawatt-hours in 2024 to a projected 426 TWh by 2030 — and every incremental watt of compute is a watt of heat that has to go somewhere.

Carrier's leadership has been explicit about this on recent earnings calls, citing commercial HVAC orders up 35% with data-center-driven demand up over 500% in a single quarter, and management pointing to a sixth consecutive year of double-digit growth in that segment. For OEMs and reps sitting inside the traditional commercial and residential value chain, this is worth watching closely — it's pulling capital and R&D attention toward a customer set (hyperscale, colocation, AI infrastructure) that looks nothing like the school districts, hospitals, and multifamily buildings most manufacturer reps have historically served.

§5What None of This Data Shows: What Happens to the Local Dealer

The face doesn't change at close. The terms above it do.

Everything above is public-market data — deal counts, multiples, sponsor names. What it can't show is what actually happens to a dealer's relationships with its external partners — manufacturers, distributors, parts suppliers, the sales process built over years — once the deal closes. That's the piece missing from every tracker, and it's worth walking through directly.

The relationship survives the transaction. Its terms don't.

Most PE buyers ask the founding owner to stay on for two to five years to manage a smooth transition, so on the surface very little changes: same face, same phone number, same day-to-day contact the dealer's staff and customers have always known. What changes is what that person is now allowed to decide on their own. A local dealer relationship with a manufacturer or distributor is typically built the old-fashioned way — trust accumulated over years, problems solved with a phone call instead of a contract clause. Once the acquiring platform strikes a national agreement upstream, the local dealer becomes a business unit inside a larger structure, and the decision-making authority it used to hold over which brand it carries, and on what terms, moves up and out of the building. The relationship doesn't end. It gets a new chain of command sitting on top of it, and the owner staying on for the earn-out period is often the one absorbing the friction of managing that change from the inside.

Not every platform moves the same way

This is where the trade press flattens something important. Certain platforms do not find it a priority to strike a national deal with an OEM, and instead allow their newly acquired dealer to continue selling its existing equipment brand. The PE group still finds margin gains in payroll efficiencies, shared back-office support, a standardized sales process, and marketing infrastructure, without touching the supply relationship at all. It's the more sophisticated operators — the ones playing for density and channel leverage, not just operational roll-up savings — who are willing to absorb the friction of forcing a primary-and-secondary supplier structure across their portfolio. Reading a platform's sophistication level from the outside often comes down to exactly this tell: does it touch the brand relationship, or leave it alone.

The profitability math that doesn't make the press release

What doesn't show up in any deal tracker is the channel economics behind these conversions. An independent dealer is, by most OEM/distributor accounts, a materially more profitable relationship than the same dealer once it's inside a PE platform. Independents make fewer demands and consume less OEM/distributor resource. Platform-owned accounts, once converted, tend to run on thinner per-unit economics and require more ongoing negotiation — because the roll-up model is built around continuously extracting more from every relationship in the stack, the OEM/distributor relationship included.

Reflects general patterns and shared sentiment over hundreds of transactions described across OEM/distributor national-account channels; not a published dataset.

Not every dealer wants this outcome — and that's the real fork in the road

The public data treats fragmentation as a uniform opportunity. In practice, dealers split into two camps well before any offer arrives. One camp is scaling to sell — building the recurring revenue, clean books, and reduced owner-dependency that Section 6 below describes, because a PE exit is the plan. The other camp is scaling to compete — dealers who've built a local, relationship-first identity into their brand and have no interest in trading it for a platform's national account terms. That second camp isn't anti-growth; it's a different definition of what winning looks like. The dealers who end up selling anyway are often the ones from that second camp who simply ran out of a succession plan — age and the absence of a transition path move them into camp one whether they intended to land there or not.

§6What This Actually Means If You're an Independent Dealer

Fragmentation creates buyer demand. It does not create automatic premium pricing.

The uncomfortable truth buried in all three data sources is that market-level tailwinds and company-level valuation are two different conversations. McKinsey's own analysis is explicit about this: market size gets investors interested, but transferability — clean financials, recurring service-agreement revenue, a team that doesn't walk out the door with the owner — is what actually earns a premium multiple. A dealer with $700 billion of macro tailwind behind them and messy books, owner-dependent sales, and no documented service contracts still prices like a distressed asset in diligence.

CT Acquisitions' underwriting-criteria data backs this up from the buyer side. What raises a multiple in 2026 HVAC diligence: documented membership/maintenance-plan revenue with retention metrics, a modern dispatch and CRM stack (ServiceTitan or equivalent), a technician roster that transfers without the owner, and clean compliance posture on the A2L refrigerant transition. What disqualifies a business outright: heavy new-construction concentration, customer concentration above 20% from a single account, and owner-dependency without a succession plan.

"When I look at an HVAC business, I am not just asking, 'How much revenue did it do?' I am asking: Does the company depend on the owner for estimating, dispatch, sales, customer relationships, and emergency decisions?"

— Michael Mayes, Homestead Service Partners

For independent operators who have no interest in selling, the practical read is different but related: the roll-ups are your new competitive set for technicians, marketing spend, and — increasingly — search visibility. Platform-backed competitors have institutional capital behind their local SEO, review generation, and paid acquisition. Standing out now runs through the same fundamentals PE underwrites for: recurring revenue depth, digital visibility, and operational maturity that doesn't depend on any single person walking through the door every morning.
