Commercial Refrigeration M&A Multiples 2026: What Buyers Pay and Who Is Buying

By Christoph Totter, Managing Partner, CT Acquisitions. Last verified July 2026. Quarterly refresh target.

A supermarket rack goes down at 2am and a store manager is watching a freezer aisle climb toward the temperature at which product has to be dumped. That call does not wait for a scheduled maintenance window, and it does not shop three quotes. Meanwhile, the same operator is staring at a federal phase-down schedule that says the refrigerant in that rack is being squeezed out of the supply chain on a fixed timetable. Those two pressures, non-discretionary emergency demand and a regulatory clock, are what make commercial refrigeration contracting structurally different from most trades a buyer will look at. They are also why the category attracts a specific kind of capital and gets priced on a specific set of questions.

We are CT Acquisitions, a buy-side M&A advisor. This guide lays out what buyers appear to pay for refrigeration-capable service businesses, who the active acquirers actually are, and the honest case against the thesis. For the adjacent trade math, our commercial HVAC business valuation guide and our mechanical contractor M&A multiples guide sit alongside this one.

The regulatory forcing function

The regulatory picture has two levers, and keeping them distinct is the whole point. One drives the volume of retrofit and replacement work. The other governs what you are legally allowed to install. They move on different schedules and they carry different risk.

The volume lever is the statutory HFC phase-down under the AIM Act of 2020 (40 CFR Part 84 Subpart A). It cuts hydrofluorocarbon supply against a baseline, with a 40% reduction effective in 2024 stepping toward roughly an 85% reduction by 2036 (EPA, per 40 CFR Part 84 and eCFR). As supply tightens, the installed base of high-GWP equipment has to be serviced, retrofitted, or replaced, which is the demand engine underneath the category. Critically, this lever is litigation-settled. The D.C. Circuit upheld EPA’s AIM Act authority on August 1 2025 in IGas Holdings v. EPA, and the Supreme Court denied certiorari on June 24 2026 in Choice Refrigerants v. EPA, No. 25-1079 (SCOTUS docket 25-1079; Sabin Center). The phase-down cap stands.

The second lever is the Technology Transitions program (40 CFR Part 84 Subpart B), which sets global warming potential (GWP) limits on new equipment. This one governs what you can put in. Under the federal dates (EPA rule text), supermarket systems faced an interim 1,400 GWP limit at January 1 2027 stepping to 150 or 300 GWP by January 1 2032; cold storage faced an interim 700 GWP limit at July 27 2026 stepping to the same 150 or 300 GWP by January 1 2032; and remote processing high-GWP systems in retail food were prohibited from January 1 2027. Section 608 of the Clean Air Act (40 CFR Part 82 Subpart F) sits underneath all of it, requiring technician certification: Type I for small appliances, Type II for high-pressure, Type III for low-pressure, and Universal for all. Leak-repair thresholds under Part 82 run 30% for industrial process, 20% for commercial refrigeration, and 10% for comfort cooling, applied to ODS refrigerants. HFCs are a separate regime: 40 CFR Part 84 Subpart C sets a 15 lb charge threshold for leak repair, effective January 1 2026.

California runs roughly a decade ahead of the federal schedule, which matters for any multi-site diligence. Under CARB rules (17 CCR 95371 et seq., under SB 1383), new stationary refrigeration systems over 50 lb of charge had to use refrigerant below 150 GWP from January 1 2022, the first such requirement in the country (per Copeland and AGAS, corroborated; CARB as origin). SB 1206 (2025) banned the sale of virgin HFC refrigerant above 2,200 GWP from January 1 2025 (secondary). California’s refrigerant management program, in force since January 1 2011, covers stationary systems over 50 lb of high-GWP charge, requires leak repair within 14 days by a certified technician, and uses tiered registration with medium and large facilities filing annual reports by March 1 (secondary sources including CoolSys and Quality Refrigeration; CARB as origin, and note that arb.ca.gov was unreachable at last verification). The practical takeaway: California hit the 150 GWP threshold on new large stationary refrigeration in January 2022 while the federal equivalent does not arrive until January 2032, roughly a decade gap that becomes a real cost and compliance variable for any operator with California locations.

Why emergency-service economics change the underwrite

Refrigeration demand is non-discretionary in a way that scheduled HVAC maintenance is not. When a rack fails, product spoils by the hour, and the customer is buying speed, not price. Buyers appear to underwrite that emergency-service revenue differently from planned maintenance because it carries pricing power the customer cannot easily shop, and because the work is recurring by nature: equipment that runs continuously fails continuously. Operators with a high share of emergency and service-agreement revenue, rather than one-off project installs, tend to be valued on the resilience of that stream. This is the same distinction that separates a service-led mechanical business from a project-led one, which we cover in our private equity platforms by sector guide.

The five customer segments and how buyers weight them

The segments that lean on ammonia or large charges raise the skill floor, which narrows the qualified-contractor pool and, in our observation, tends to support pricing at the higher end of the operator range.

What buyers pay

Before any figure, the tier discipline: platform-scale and public-company comparables are not what a lower middle market operator trades at, and we label the tier on every one.

Below roughly $1M of owner earnings, refrigeration contracting businesses are typically priced on seller’s discretionary earnings (SDE), not EBITDA, because the owner’s labor and add-backs dominate the economics. In that band, mechanical and HVACR businesses have tended to transact around 2.0x to 3.0x SDE, with PeerComps data on NAICS 238220 (the broad plumbing, heating and A/C contractor code) showing roughly 3.26x SDE. As earnings scale above roughly $1M, the convention shifts to EBITDA. PeerComps shows about 4.06x EBITDA on the same code; businesses with $5M to $15M of adjusted EBITDA have tended toward 4.0x to 5.5x EBITDA; and the IBBA Market Pulse reported a 4.8x EBITDA median for the $2M to $50M range in Q4 2025 (per PeerComps and IBBA Market Pulse). The transition from SDE to EBITDA is not cosmetic; stating a 5x EBITDA number on a sub-$1M-earnings business misrepresents how it will actually be bought.

Within commercial HVAC more broadly, the full band runs about 5x to 12x EBITDA, with premium planned-maintenance-agreement platforms toward 9x to 12x and standalone controls businesses around 6x to 9x. First Page Sage put service-led commercial HVAC at 5.5x to 7.8x EBITDA in 2025 (per First Page Sage).

The refrigeration specialty band we observe is roughly 6x to 9x EBITDA, and this is an internal CT Acquisitions observation, not a cited third-party figure. It is a subset of the commercial-HVAC service-led band of 6.5x to 9x that we see in our engagements, applying to businesses above the SDE-to-EBITDA transition with genuine service depth. We flag it as our observation precisely because no independent third party publishes a refrigeration-contracting-specific band; treat it as directional.

What separates operators inside a band

Two refrigeration businesses with identical EBITDA can price a couple of turns apart. The variables buyers appear to reward are the share of revenue under service agreements versus one-off projects; the density of certified technicians relative to the work (Section 608 certification is a legal requirement, so credentialed headcount is a real barrier, not a nicety); demonstrated capability in low-GWP and natural-refrigerant systems, particularly CO2 transcritical and ammonia; remote monitoring that turns reactive calls into managed uptime; customer concentration, where a book spread across many accounts prices better than one anchored on a few chains; and the geographic coverage that lets an operator actually answer that 2am call. CO2 and ammonia competence is worth isolating: roughly 2,800 US supermarkets ran on transcritical CO2 in 2024, about 4,100 across North America, at roughly 5.8% North American penetration (per ATMOsphere 2024, industry-association vendor data), and CO2 carries a GWP of 1, which makes that capability future-proof against the phase-down. Ammonia dominates industrial and cold storage and is gated by OSHA PSM at a 10,000 lb anhydrous ammonia threshold quantity (29 CFR 1910.119 App A, EPA RMP under 40 CFR Part 68 also triggering), which raises the servicing skill and cost floor and thins the qualified pool further.

The technician constraint is structural across the trade. BLS reports roughly 410,000 to 425,000 HVACR mechanics and installers employed (SOC 49-9021), a median wage near $61,010, about 8% projected employment growth 2024 to 2034, and roughly 40,100 annual openings (per BLS OEWS and Employment Projections; bls.gov returned access errors at verification, BLS as origin). Certification is a legal gate on top of a labor shortage, which is why credentialed technician density shows up in what buyers pay.

Who is actually buying

The buyer universe has one dedicated national commercial-refrigeration platform, and beyond it the acquirers are mechanical and facility-services platforms that carry refrigeration as one capability rather than as their whole business. Stating that plainly matters, because it shapes who an owner should expect across the table.

The reason a buyer universe exists at all is that the trade is structurally fragmented. No federal statistical code isolates commercial-refrigeration contracting; it sits inside NAICS 238220 (plumbing, heating and A/C contractors) alongside HVAC and plumbing, so any refrigeration-only figure is an estimate rather than a clean count. That broad contractor code held roughly 109,601 establishments against about 1.18 million employees in 2022, close to 11 employees per establishment on average (per US Census Bureau, County Business Patterns 2022; census.gov was not directly reachable at verification, so this is carried on the Census figure as origin). A trade built on small, owner-operated shops is the precondition for a roll-up, and it is why national platforms and regional strategics can keep acquiring without exhausting the target pool.

Coolsys is the one dedicated national commercial-refrigeration and HVAC services platform, with refrigeration at its core, owned by Ares Management since March 21 2019 (prior owner Audax, roughly 2015 to 2019; per coolsys.com, verified 2026-07-22). Coolsys absorbed Source Refrigeration, so Source is now Coolsys (per coolsys.com/our-brands/source-refrigeration). To be explicit about a common error: EMCOR did not acquire Source Refrigeration; Source belongs to Coolsys under Ares.

Beyond Coolsys, the active buyers carry refrigeration as one line among many. EMCOR Group (NYSE: EME) is public, with refrigeration sitting inside its US Mechanical Construction and Facilities Services segment rather than as a standalone line (per SEC and company filings). Comfort Systems USA (NYSE: FIX) is a public MEP contractor whose refrigeration exposure is minimal and incidental, weighted toward data-center and industrial work, so it is not properly a refrigeration buyer. Service Logic, a commercial HVAC and mechanical services platform with refrigeration and controls capability, was acquired by Bain Capital at roughly $3.1B enterprise value, closing December 16 2025, from Leonard Green with Mubadala co-investing (per leonardgreen.com); it is the largest recent refrigeration-capable trade. Two names that commonly get miscategorized: Legence (Nasdaq: LGN) is a public company after its roughly September 12 to 13 2025 IPO that raised about $728M, with Blackstone still controlling around 74% following its 2020 acquisition, and its work is data-center and life-science MEP rather than refrigeration; and Sila Services, backed by Goldman Sachs Alternatives since an announced November 2024 deal from Morgan Stanley Capital Partners, is residential HVAC, plumbing and electrical, not a commercial refrigeration buyer (secondary).

One distinction owners should hold onto: Hill Phoenix (also styled Hillphoenix, part of Dover, NYSE: DOV) is a refrigeration equipment manufacturer, not a contractor, and does not belong on a list of companies acquiring refrigeration service businesses (per dovercorporation.com and hillphoenix.com). On deal counts, honesty requires saying there is no independent refrigeration-contracting-specific deal count; only HVAC-wide figures exist, with private equity add-ons around 41% of HVAC deal volume, PE HVAC add-ons up about 88% year over year through June 2025, and HVAC EV/EBITDA around 10.9x in 2025 versus about 9.0x in 2024 (per Capstone and PKF O’Connor Davies). Those are HVAC-wide, not refrigeration-isolated.

The honest case against

We would rather an owner hear the counter-thesis from us than discover it in diligence. Five points deserve weight.

Mandated demand is not mandated pricing. The phase-down guarantees that work exists; it does not guarantee margin. Pure compliance work tends to commoditize toward the minimum standard, and a contractor doing generic swap-outs at the lowest qualifying spec competes on price like anyone else.

The retrofit cycle is finite. The phase-down creates a pulse of replacement work, but a pulse has an end. A buyer underwriting a five-year hold will ask what the recurring base looks like after the retrofit wave passes, and an operator whose recent growth is mostly one-time conversion projects has to answer that.

Regulations change, and not always in the direction of more demand. The concrete live example is from 2026 itself: a reconsideration rule published May 26 2026 (NPRM October 3 2025) relaxed near-term Technology Transitions limits, raising the interim GWP ceiling to 1,400 for supermarket, remote-condensing, and cold-storage systems and extending no-action assurance to September 1 2026 (per EPA rule text). The equipment rule that governs what you install was softened. The distinction that saves the thesis is that the statutory phase-down cap, the volume driver, held up in court and is litigation-settled after the SCOTUS cert denial of June 24 2026, while the install rule is the piece that moved. Regulatory risk here is not hypothetical; it is documented within the current year.

Customer concentration is structural. A refrigeration contractor built on three supermarket chains has real dependency risk, and losing one anchor account can reset the economics. Buyers price that, and an owner should expect concentration to be a central diligence line.

Project-heavy retrofit is still project work. Installation and conversion projects carry the same install discount that project revenue carries in any mechanical trade. Revenue that looks like growth on a chart can be the low-margin, non-recurring kind, and it is valued accordingly. The same tension appears in adjacent regulated trades, which we treat in our private equity fire and life safety guide and our elevator business valuation guide.

Preparing over 18 to 36 months

Owners who want a service-tier outcome rather than a project-tier one tend to spend the run-up doing a few concrete things. Shift revenue mix toward service agreements and recurring maintenance and away from one-off installs. Build and document certified technician density, since Section 608 credentials are a legal barrier a buyer will verify. Develop demonstrable CO2 and, where relevant, ammonia capability, because those competencies map directly to the phase-down and to the harder segments. Diversify the customer book to reduce concentration on any single chain. Instrument the fleet with remote monitoring so uptime becomes a managed, provable metric. And clean up the financials so add-backs are defensible and the SDE-to-EBITDA story is clear at the earnings level the business will be sold at. None of this is fast, which is why the honest window is measured in years, not months.

Frequently asked questions

What EBITDA multiple do commercial refrigeration businesses sell for?
The refrigeration specialty band we observe is roughly 6x to 9x EBITDA for businesses above the point where pricing shifts from SDE to EBITDA. That is an internal CT Acquisitions observation, a subset of the service-led commercial HVAC band, not a cited third-party figure. Smaller businesses below roughly $1M of earnings are priced on SDE instead.

When does a refrigeration business get priced on SDE versus EBITDA?
Below roughly $1M of owner earnings, businesses are generally priced on seller’s discretionary earnings (SDE), often around 2.0x to 3.0x. Above roughly $1M, the convention shifts to EBITDA. Applying an EBITDA multiple to a sub-$1M-earnings business misstates how it will actually be bought.

Who is the largest dedicated commercial refrigeration acquirer?
Coolsys is the one dedicated national commercial-refrigeration and HVAC services platform, owned by Ares Management since March 21 2019 (verified 2026-07-22). Beyond Coolsys, buyers are mechanical and facility-services platforms carrying refrigeration as one capability, such as EMCOR and Service Logic under Bain Capital.

Did EMCOR acquire Source Refrigeration?
No. Source Refrigeration is part of Coolsys, which Ares Management owns. EMCOR is a separate public contractor that carries refrigeration inside its US Mechanical Construction and Facilities Services segment.

Is the HFC phase-down actually settled law?
Yes. The D.C. Circuit upheld EPA’s AIM Act authority in August 2025, and the Supreme Court denied certiorari on June 24 2026 in Choice Refrigerants v. EPA (No. 25-1079). The statutory phase-down cap stands. Separately, the Technology Transitions equipment rule was relaxed by a reconsideration rule published May 26 2026, which raised near-term GWP limits.

Why does CO2 or ammonia capability matter to a buyer?
Both are low-GWP paths that align with the phase-down; CO2 has a GWP of 1. Roughly 2,800 US supermarkets ran transcritical CO2 in 2024 (per ATMOsphere 2024). Ammonia dominates industrial and cold storage but is gated by OSHA PSM at a 10,000 lb threshold, which thins the qualified-contractor pool and raises the cost floor.

How is California different for refrigeration compliance?
California runs about a decade ahead of the federal schedule. New large stationary refrigeration had to use refrigerant below 150 GWP from January 1 2022 under CARB, while the federal equivalent does not arrive until January 1 2032. For multi-site operators, that gap is a real diligence variable (CARB as origin; secondary sources).

How should an owner prepare for a sale?
Over 18 to 36 months, shift the revenue mix toward service agreements, build documented certified-technician density, develop CO2 and ammonia capability, diversify the customer book away from a few anchor chains, add remote monitoring, and clean up the financials so the SDE-to-EBITDA story is defensible at the earnings level the business will be sold at.
