US HVAC M&A
Residential and light commercial HVAC has been one of the most heavily consolidated trades in the United States for the better part of a decade. Private equity built regional platforms across the Sun Belt first, then moved into the Midwest and Northeast, and those platforms now need bolt-ons to keep growing. That is the single most important fact for an owner: you are usually not selling to one buyer, you are selling into competition between several.
The number that decides your multiple is the proportion of revenue under a recurring service or maintenance agreement. A membership base that renews every year is annuity income. Replacement and install revenue is not, however profitable it looked last summer. Two companies with identical revenue and identical EBITDA can price three or four turns apart on this one factor alone.
American buyers underwrite differently below and above roughly $500K of adjusted profit. Above it, you are in EBITDA territory and talking to platforms, strategics and lower-middle-market private equity. Below it, you are usually talking to an individual buyer or a search fund using an SBA 7(a) loan, and the price is quoted as a multiple of seller's discretionary earnings with your compensation added back.
Add-backs are where US processes are won and lost. Owner salary above market, personal vehicles, family members on payroll, one-time legal costs: all of these can legitimately be added back, but only if they are evidenced. A quality of earnings review will test every one of them, and add-backs that cannot be documented get removed from the number your multiple is applied to.
State licensing and technician retention are diligence items in every US HVAC deal. The buyer needs to know the license transfers or that a qualifying individual stays, and they need to believe your technicians will not walk. In a market where every operator is short of labor, a stable, well-paid technician bench is a genuine part of the valuation rather than a nice-to-have.
Our 30-factor model separates recurring service agreement income, replacement work and new construction, then prices each on its own multiple rather than blending them. It also tests your add-backs the way a quality of earnings provider will, before a buyer does it for you.
Service agreement base: Members under an annual agreement are annuity income. Buyers count them, check renewal rates and price them separately from install revenue.
Replacement demand is non-discretionary and repeats. New construction is cyclical and priced closer to a project business.
Adjusted EBITDA quality: Every add-back has to be documented. Unevidenced owner expenses get stripped out during quality of earnings, taking the price with them.
Technician retention: Tenure, pay bands and turnover. A buyer paying for capacity needs to believe the capacity stays after closing.
State license transfer, or a named qualifier who remains post-closing, is a condition of most deals.
Customer concentration: Any single commercial account above 15 to 20 percent of revenue usually converts part of the price into an earn-out.
Gross margin by revenue line
Buyers rebuild your P&L by service, replacement and install. Blended margin hides the line that is actually funding the business.
Fleet and systems: Vehicle age and a real field service management system affect both the capital a buyer must inject and how quickly they can integrate you.

How the US market differs
How the US market differs
Buyer appetite for HVAC is national, but the price you achieve and the type of buyer at the table vary by market.
The most competitive acquisition market in the country. Year-round cooling demand, population growth and a dense field of private equity platforms mean well-run membership-led businesses often see multiple bidders.
Expect platforms to move quickly and to underwrite your membership base line by line.
Heavy consolidation, strong replacement demand and a large residential base. Storm and humidity-driven service work is normal here, and buyers understand it, but they will normalise any one-off spike in your numbers.
We already act for owners in this market. See our Florida page for regional detail.
Higher labor cost, tighter regulation and Title 24 energy requirements. Buyers pay for compliance capability and for technicians who can deliver it, and they price licensing risk carefully.
Electrification and heat pump work is a growth story buyers will credit if it is evidenced.
Dual-season heating and cooling demand produces steadier annual revenue but a shorter replacement window. Commercial mechanical contractors here are consolidating later than the Sun Belt, which can mean less competition but also more room to be first.
Union arrangements, where they exist, are a diligence item rather than a barrier.
What multiple will I get for my HVAC business in 2026?
It depends almost entirely on recurring revenue. A service-agreement-led company with more than $1M of adjusted EBITDA typically prices at 7.5x to 10.5x. A mixed service and replacement business sits around 6.0x to 8.0x. A project or new-construction-led company usually lands at 4.0x to 6.0x. These are DealFlowAgent estimates, not a quotation for your business.
What is the difference between SDE and EBITDA, and which applies to me?
Seller's discretionary earnings adds your own compensation and personal expenses back to profit, and is used when the buyer will run the business themselves. EBITDA assumes a market-rate manager in your seat and is used when a platform or strategic acquires you. Broadly, below about $500K of adjusted profit you will be quoted on SDE, above it on EBITDA. The multiples are not comparable between the two.
How much are my maintenance agreements worth?
Buyers value the agreement base on renewal rate, average annual value and the replacement revenue it pulls through. A membership base with documented renewal above 80 percent is treated as annuity income and prices at the top of the range. Verbal or lapsed agreements that renew by habit are not credited in the same way.
Can I sell my HVAC business without my technicians finding out?
Yes. The company is presented under a blind profile describing revenue mix, membership base and market without naming it. Buyer identities and full financials are exchanged only after a confidentiality agreement is signed. Key staff are usually told once a letter of intent is signed.
How long does it take to sell an HVAC company in the US?
Six to nine months from signed mandate to closing is typical. Quality of earnings work, license transfer and financing timelines usually set the pace rather than commercial negotiation. SBA-financed deals at the smaller end can take longer because of lender underwriting.
Will a buyer make me stay on after the sale?
Usually for a transition period of three to twelve months, and often with part of the price tied to an earn-out where the business depends on your relationships. Reducing owner dependence before you go to market is the most reliable way to shorten that commitment and take more of the price at closing.
What lifts the price most before a sale?
Converting one-time customers onto maintenance agreements, price-reviewing agreements that have not moved in years, documenting every add-back with evidence, putting a general manager between you and daily operations, and cleaning up financial reporting so service, replacement and install can be seen separately.
What reduces the price during due diligence?
Add-backs with no supporting evidence, membership counts that include lapsed customers, customer concentration disclosed late, technician turnover above market, unresolved licensing or warranty liabilities, and cash-basis books that cannot be converted to accrual for a quality of earnings review.
SDE or EBITDA: which figure will a buyer apply a multiple to?
It depends on the size and the buyer. Below roughly $1M of earnings, buyers and SBA lenders generally work in seller's discretionary earnings, which leaves one owner's compensation in the number. Above it, platform buyers work in adjusted EBITDA with a market-rate general manager costed in, because they are not buying a job. The same company can therefore be quoted on two different earnings figures and two different multiples, and comparing a quoted multiple without knowing which base it sits on is how owners end up disappointed. Our guides to seller's discretionary earnings and how to value a business set both out with worked arithmetic.
Will an asset sale or a stock sale suit me better?
Most lower middle market HVAC deals in the United States are structured as asset purchases, because the buyer gets a stepped-up tax basis and leaves historic liabilities behind. Sellers usually prefer an equity sale for the opposite reasons. The gap is real money and it is settled in the price and the indemnities rather than by argument. Where an asset sale proceeds, the price is allocated across the IRS asset classes on Form 8594 under the section 1060 residual method, and that allocation changes what you actually keep. Agree it with your CPA before signing the letter of intent, not during closing.
Does my contractor license transfer with the business?
Not automatically, and this is one of the most common causes of delay we see. HVAC licensing is administered state by state, and where the qualifying license is held personally by the owner rather than by the company, the buyer needs a qualifying individual of their own in place before or at closing. Confirm early who holds the license, whether the company holds it in its own right, and what the state requires on a change of control. It is a straightforward question to answer in week one and an expensive one to discover in week twenty.
