Revenue does not determine what your HVAC company is worth. EBITDA margin, service mix, and customer concentration all matter, and none of them fit in one number. This report shows what closed and LOI-stage deals actually show, what practitioners advise directionally, and where TradeSworn has built its own synthesis, clearly labeled as such.
Revenue does not predict your exit multiple by itself. EBITDA margin, service mix, and customer concentration all move it. Two shops can produce valuations $5M+ apart at the same revenue level. This report shows what the evidence actually supports for each factor, and where it doesn't.

"The gap between a 4.00× and a 10.93× LOI-stage multiple is not a revenue story. Margin alone doesn't explain it either. What separates them is everything a five-line table cannot show."

Approximately 52% of HVAC companies that go to market do not sell. First Page Sage reports that buyer hesitation in these cases typically involved owner dependence and customer attrition, among the reasons its research identifies. Neither is a revenue problem, and both are addressable before going to market. Separately, in a general lower-middle-market survey (not HVAC-specific), Axial's 2026 Lower Middle Market Outlook (n=107 advisors and investors) finds that among deals that didn't close as intended, 48.7% were paused rather than abandoned outright, with valuation misalignment and macroeconomic uncertainty cited most often.
Advisor-led, competitive sale processes are associated with approximately 25% higher sale prices than owner-led transactions within Axial's platform data (Axial, 2026). Broader outreach creates multiple simultaneous buyer conversations, which creates competitive pressure an owner negotiating alone cannot easily replicate.
What we can say, using PKF O'Connor Davies' actual commercial HVAC services-segment findings: transaction multiples run north of 10x EBITDA for high-revenue-visibility, high-margin businesses with a large service component. Market participants treat $10M+ EBITDA as the scale where multiple expansion becomes most significant, well above this report's $3M-$30M revenue scope. Separately, PKF notes that high-quality HVAC services businesses with $0.5M-$5M EBITDA — the range most relevant to this report's audience — have also traded at healthy multiples, without stating a specific number.
PKF's distribution-segment findings (a different part of the HVAC industry, covering equipment and parts distributors rather than service contractors) state that gross margins above 30% and EBITDA margins above 15% are typically viewed as symptomatic of premium market positioning, entrenched customer relationships, and operational efficiency, with 20-30% gross margin / 10-15% EBITDA margin considered strong and in line with market dynamics. We report this here for transparency, because it's a real PKF finding worth knowing, but we are not applying it to commercial HVAC contractors as a benchmark. If you want a margin-to-multiple relationship you can act on for your own shop, ask your M&A advisor or CPA to build one from your specific deal comps; we don't have a source that supports one at the contractor level.
What share of total revenue, and separately what share of gross profit, comes from your single largest customer. Revenue share and profit share can differ meaningfully if margin varies by account.
Whether the relationship is governed by a written, multi-year agreement or an at-will arrangement, and what notice period or cause is required for either party to exit.
How many renewal cycles the relationship has been through, and whether pricing, scope, or terms have changed at each renewal.
Whether the account is managed by the owner personally, by a dedicated account manager, or by a broader team, and what would happen to the relationship if the owner were no longer involved day to day.
What adjusted EBITDA and margin look like with this customer's revenue and any directly associated cost removed. This is the number a buyer is likely to model whether or not they say so explicitly.
Cherry Bekaert, which has advised on over 100 home services deals, documents a structural shift in PE buyer demand: there are now three times as many buyers with active investments in the home services sector compared to five years ago, with more anticipated to enter. Separately, in its 2025 Trends and 2026 Outlook report, Cherry Bekaert notes that HVAC services were a major focus of PE investment in 2025 despite a small dip in aggregate capital, with PE firms and their portfolio companies accounting for a majority of transactional activity in HVAC M&A.
Tariff pressures are expected to accelerate PE investment in home services, as HVAC is viewed as essential, needs-based demand that hedges against economic volatility. Consistent with PKF O'Connor Davies: the consolidation window in commercial HVAC remains open.
A dimension absent from most HVAC valuation discussions is the lender's underwriting view, which directly affects what buyers can actually pay. The U.S. Small Business Administration named Live Oak Bank the nation's most active SBA 7(a) lender by dollar amount for fiscal year 2025 (ended September 30, 2025): more than $2.8 billion across 2,280 approved loans. Live Oak operates a dedicated HVAC and plumbing contractor lending team.
TradeSworn interpretationSBA financing is a common structure for buyers without institutional PE backing. The cited Live Oak pages describe its lending process in general terms but do not specify which financial variables its underwriters weight most heavily. Neither Live Oak nor the SBA states that its underwriting criteria match what PE buyers scrutinize; in our own view the two likely overlap in practice, since both ultimately care about the durability of profit, but that overlap is our inference, not a sourced claim. Clean books and low owner dependence are, at minimum, a reasonable place to start for either kind of process.

See the BenchmarkThis benchmark was produced by TradeSworn, LLC, synthesizing publicly available M&A transaction data, advisory firm research, and industry publications focused on the HVAC sector. TradeSworn conducted desk-based secondary research for this report and collected no proprietary transaction data. All figures represent ranges drawn from the sources listed below, interpreted through a commercial HVAC lens for the $3M-$30M revenue band.
Scope: Commercial HVAC contractors, $3M-$30M annual revenue, United States, primarily 2024-2026 transaction data. Some sources blend residential, commercial, and industrial HVAC, or blend HVAC services with HVAC distribution. Where that occurs, this report labels the source population explicitly and, where a commercial-services-specific figure was not available, either omits the figure or clearly frames it as a directional, non-benchmark observation.
LOI stage vs. closing: Axial's five-transaction table in Section 3 presents valuation multiples as of the LOI (offer) date for deals that subsequently closed. Axial's own column heading is "Offer date (LOI)." These multiples are not verified final closing consideration; deal terms, working-capital adjustments, and post-LOI negotiation can change the final number. This report uses "received a [X] multiple" or "LOI-stage multiple" rather than "achieved" or "closed at" for exactly this reason.
Distribution vs. services: PKF O'Connor Davies' 30% gross margin / 15% EBITDA margin premium-positioning threshold is stated for the HVAC distribution segment. This report does not apply it to commercial HVAC services or publish a contractor EBITDA-margin tier table, because we could not locate a comparably transparent, contractor-specific threshold. Section 6 reports PKF's actual services-segment findings and its distribution-segment findings separately.
What this report does not claim: This report does not publish a numeric buyer-type premium, a deferred-consideration haircut, or a customer-concentration discount schedule, because no source we reviewed supports one. Where an earlier draft stated such a figure, we removed it rather than relabel it as illustrative; a labeled-but-invented number is still invented.
Limitations: Private M&A transaction data is inherently incomplete. Individual company valuations depend on business-specific characteristics, buyer type, market conditions, deal structure, negotiation, and timing. This report is for educational and media purposes. Consult qualified M&A advisors and CPAs before making exit decisions. All source data is independently verifiable at the publications listed and linked above.
Revision history: This version removes an unsupported 16.9x headline figure, corrects a buyer-pool transcription error (817, not 818), replaces "achieved"/"closed at" language for LOI-stage multiples, replaces a non-reproducible profile-band table with Breakwater's own published ranges, removes an unsupported contractor EBITDA-margin tier table, removes an unsupported deferred-consideration haircut and customer-concentration discount schedule, removes an unverifiable HVACR Business citation, and corrects Live Oak Bank's lending figures to its confirmed FY2025 results.
