A revenue figure is the beginning of the question.
Annual sales describe scale. They do not show the cash a buyer can earn after technician payroll, dispatch, marketing, materials, insurance, vehicle costs and management. Start with a reconciled view of the company’s earnings, then ask how reliably those earnings can continue under new ownership.
An owner-operated residential service company and a management-run commercial mechanical contractor need different comparisons. Customer mix, project exposure and the owner’s actual responsibilities belong in the analysis.
What should a valuation explain?
The earnings measure, accepted adjustments, relevant comparable businesses, assumptions about assets and working capital, and how the proposed deal structure changes the result.

SDE and EBITDA answer different questions.
| Measure | What it describes | What to examine |
|---|---|---|
| SDE Seller’s discretionary earnings | Earnings available to a single owner-operator, including supportable owner compensation and discretionary adjustments. | Which owner’s compensation is included? What work will the buyer perform? Are add-backs documented and nonrecurring? |
| EBITDA Earnings before interest, taxes, depreciation and amortization | An operating earnings measure before those specified expenses. Adjusted EBITDA must identify and support its adjustments. | Is management paid at a realistic replacement cost? Are one-time costs actually one-time? Is ongoing capital expenditure being overlooked? |
Do not multiply EBITDA by an SDE multiple, or treat owner compensation as freely available when the business needs to hire someone to perform that work. Ask your advisor and CPA to reconcile the numbers. These definitions are general financial explanations; they do not determine which measure fits your company.
Published HVAC multiples: a bounded benchmark.
BizBuySell’s 2021–2025 reported HVAC sales cohort shows sold-business SDE multiples of 1.99× at the lower quartile, 2.58× at the median and 3.33× at the upper quartile.
The marketplace describes its cohort as primarily locally owned small businesses. These are historical sold-price benchmarks, not asking-price multiples, EBITDA multiples or a valuation of a particular company. Original HVAC benchmark report
The right question is “comparable to what?”
A benchmark is useful only when the earnings definition, business model and transaction scope are comparable. A scaled commercial contractor or institutional platform needs a different analysis.

What to examine in an HVAC business.
Earnings quality
Separate recurring operating profit from one-time items. Support each proposed adjustment with records a buyer can verify.
Revenue mix
Break out service, maintenance, replacement and new construction. Show margins and trends for each rather than relying on total sales.
Maintenance relationships
Document active agreements, renewals, customer retention and service obligations. Contract revenue is useful only when its economics hold up.
People and leadership
Clarify who runs dispatch, sales and field operations. A company that depends on the owner needs a practical transition plan.
Customer concentration
Show the largest accounts, contract terms and collection history. Losing one large customer should not be hidden in the totals.
Capital and working capital
Prepare fleet, equipment and inventory schedules. Understand cash needed for payroll, receivables, warranties and ongoing projects.
Residential versus commercial
Make the comparison specific. Residential service may rely on marketing performance and repeat customers. Commercial work may involve contracts, concentration, project margins, backlog and bonding. Neither label automatically earns a premium.
Service versus new construction
Show the economics of each revenue stream, including seasonality and cash collection. A long backlog can include low-margin work, and an active maintenance agreement can carry significant service obligations. Buyers need the underlying records.
Owner dependence and technician retention
Describe what happens when the owner is away. If key accounts, estimating or technical work depend on one person, prepare a transition plan. Document workforce responsibilities and ask the buyer how compensation, benefits and retention would be handled.
These are practical review questions, not numerical premiums or discounts. Their effect depends on the business and transaction evidence.
A sale price is not the same as money in your pocket.
Compare the stated price with cash at closing, debt repayment, fees, working-capital adjustments and taxes. Separate contingent earnouts, seller notes and rollover equity from money you can actually use at closing.
Asset allocation and transaction structure can change tax treatment. Review them with your CPA and attorney before negotiating final terms. IRS sale-of-business guidance
