What an HVAC Business Is Really Worth (and the 5 Decisions That Move the Number)

You run three to five trucks, about $1.4M in revenue and roughly $320K in seller's discretionary earnings. Someone told you HVAC sells for 7 to 12 times, so you have quietly been running $2M-plus of math in your head.

That math is wrong, and the reason it is wrong is the same reason your business is worth less than you think. You are still the only person who can price a complex replacement, and you still personally hold the maintenance relationships.

The short version

• An owner-dependent service business transacts near 1.65x SDE; an owner-light one near 3.5x. On a $300,000-SDE business, that spread is $555,000.
• The 7 to 12 times you have seen quoted is an EBITDA multiple for a PE platform roll-up, not the SDE multiple a one-to-five-truck owner sells at.
• A $500K-$2M owner-operated HVAC business lands at a low-single-digit SDE multiple, set by the canon Service-bucket range.
• The most expensive owner-dependence in HVAC is the maintenance-agreement book plus the replacement quoting you do in your head.
• 86% of owners have no professional valuation or only a rough estimate, so most are anchored to the wrong number.

Below: the real SDE number, why 7 to 12 times isn't yours, and the five decisions that move it.

What an HVAC business is actually worth

An HVAC business is worth a multiple of its seller's discretionary earnings, and for an owner-operator that multiple is low single digits, not the 7 to 12 times quoted on broker pages. HVAC maps to the Service business-type bucket, where the SDE multiple runs about 2.4 to 3.2 times at $250K-$500K SDE and 2.9 to 3.9 times at $500K-$1M.

The all-industry median sits near 2.0 to 2.5 times SDE. The 7 to 12 times is an EBITDA figure for a different kind of buyer.

Those ranges are SDE multiples drawn from a decade of closed transactions, not list prices. They are the Main Street number a working owner actually closes at.

Run the math on the $320K SDE the lead operator carries. At the $250K-$500K band that is roughly $768K to $1.02M, not the $2M-plus the 7-to-12 framing implied.

The reason the broker number felt close is that it is a real number for a real buyer, just not for this seller. A PE roll-up does pay multiples that high, which is what makes the confusion so durable.

Here is the full canon Service-bucket range by SDE band, the same table the diagnostic uses:

• Under $100K SDE: 1.3 to 2.3 times
• $100K to $250K SDE: 1.9 to 2.5 times
• $250K to $500K SDE: 2.4 to 3.2 times
• $500K to $1M SDE: 2.9 to 3.9 times
• $1M-plus SDE: 3.5 to 4.5 times

Those bands are the Service-bucket canon, calibrated across a decade of closed transactions; HVAC sits inside that bucket, and the band is the honest starting point for an HVAC shop's number.

The deeper math behind that band, and where your specific number lands, is the work of the full HVAC valuation walkthrough. Start there for the multiple itself.

The number you've seen quoted is an EBITDA platform number

The 7 to 12 times is real, but it is not yours. It describes two different worlds, and the gap between them is the whole point.

Platform world. A private-equity firm rolls up dozens of HVAC companies into one consolidated entity, prices it on EBITDA, and pays 7 to 12 times because it is buying scale, management depth, and a portfolio that no single owner anchors.

Owner-operator world. A buyer or successor purchases your one-to-five-truck business, prices it on SDE because your earnings include your own pay and add-backs, and pays a low-single-digit multiple because the business still depends on you.

EBITDA strips out the owner's compensation and assumes a management layer is already in place. SDE adds the owner's pay back in, because the buyer has to replace you.

That single accounting difference is what splits the two numbers. The same business looks like 9 times to a broker and 3 times to the person writing the check.

There is a second reason the platform multiple is higher, and it is the one that matters to you. The roll-up is buying a company that already runs without any one owner; you are selling a company that still runs on you.

A platform pays up because the management risk is already solved across its portfolio. An owner-operator buyer pays down because that risk is the first thing they have to solve after closing.

That is why the SDE-versus-EBITDA gap is not just accounting. It is a direct readout of how much of the business still sits on the owner.

That gap is not unique to HVAC. The same EBITDA-versus-SDE split shows up in every trade, which is why the cross-trade version of this number is worth a look.

The clean way to see the conversion, line by line, is the SDE-versus-EBITDA method. It shows exactly where the platform number and your number split apart.

The 5 decisions that move the number

Your sale price is not fixed by your trade or your revenue. It is set by five decisions you control, and each one moves you along the 1.65x-to-3.5x spread.

Each decision below routes to the deep method for it. Read the one that matches where you are.

• Decision 1, the maintenance-agreement book is the single most expensive owner-dependence in HVAC, the recurring book plus the replacement quoting you do in your head. Making that book transferable is what closes the discount, the work of selling an HVAC business for more than the owner-dependence discount.
• Decision 2, whether the business runs without you in the quoting chair, is what a buyer pays the higher multiple for. The reliability methods that take you out of that chair live in running an HVAC business without being the one who quotes every job and produce a business that runs without you.
• Decision 3, the service manager who holds the quoting standard, is how your pricing judgment stops being yours alone. That hire is covered in hiring an HVAC service manager without losing the quoting standard.
• Decision 4, the clean SDE story a buyer can trust, means add-backs and books that hold up under scrutiny. The method for building that defensible number is how to value a small business the way a buyer will.
• Decision 5, the buyer's pre-bid read of the same numbers, is these exact levers run in reverse to set an offer. The buyer's side is the pre-bid analysis of an HVAC deal.

Why the maintenance-agreement book decides most of it

Of the five decisions, one carries more of your number than the rest. It is the maintenance-agreement book, and the replacement quoting you do in your head sits right next to it.

Two things make this the most expensive owner-dependence in HVAC. The recurring maintenance relationships are personal to you, and the pricing judgment on complex replacements lives nowhere but your experience.

A buyer looks at both and sees risk they cannot transfer. That risk is what they price as the discount.

The recurring book itself is a real asset. Maintenance and service agreements are a genuine recurring book, and a transferable one lifts the multiple toward the higher end of the band.

The discount is not the existence of the book. It is that the book and the quoting both run through one person, you, and a buyer prices that single point of failure as risk.

A book held by a named service manager, on documented terms, with a pricing standard a second person can apply, is worth more than the same revenue held in your head. That conversion is the difference between the low end of the band and the high end.

Picture the buyer's first question on your maintenance contracts. They are not asking how many you have; they are asking what happens to renewals when you are no longer the one the customer calls.

The same applies to the replacement quote. If the only correct price for a complex changeout lives in your judgment, the buyer is purchasing a business that cannot quote its highest-margin work without you in the chair.

This is why the maintenance book is the lever, not a footnote. Make it transferable and you move the multiple; leave it personal and you cap it, no matter how strong the revenue looks.

Where an HVAC deal sits with a lender

A buyer usually borrows to close, which means the lender's read of your trade quietly shapes what a buyer can pay. The broker page never shows this, but it works in HVAC's favor.

HVAC maps to the Service bucket, and Service sits at the low-risk end of the SBA charge-off ordering. Professional Services and Service anchor the low end of realized SBA charge-offs; Food Service and Retail anchor the high end.

A lower-risk trade is one a lender finances with less friction, which means a buyer can support a stronger offer.

This is a confidence read, not a discount. The risk tier never lowers your estimated value; it tells a buyer the financing is more likely to clear, which is one less reason for them to bid low.

How to find your real number

The five decisions are owner-controlled and rankable, which means your real number is knowable today, not on the day a broker shows up. The question is where this specific business sits on the 1.65x-to-3.5x spread.

That is what the free Keystone diagnostic measures. It scores how much of the business still runs on you and returns an estimated sale price calibrated against 10 years of BizBuySell Insight Reports and 1.6M-plus SBA 7(a) loan records.

FAQ

What multiple do HVAC businesses sell for?

An owner-operated HVAC business in the $500K-$2M range sells at a low-single-digit multiple of seller's discretionary earnings, roughly 2.4 to 3.2 times at $250K-$500K SDE and 2.9 to 3.9 times at $500K-$1M. The 7 to 12 times you may have seen quoted is an EBITDA multiple for platform roll-ups, not the owner-operator's number.

How do you value an HVAC company?

You apply an SDE multiple from the Service bucket to the business's seller's discretionary earnings, landing low or high in the band based on owner-independence, the maintenance book, and clean financials. SDE includes the owner's pay, which is why it differs from the EBITDA multiple brokers quote.

What makes an HVAC business worth more?

A transferable maintenance-agreement book and a quoting standard a service manager can hold, rather than relationships and pricing judgment that live only with the owner. Owner-light HVAC businesses transact near 3.5x SDE and owner-dependent ones near 1.65x, a $555,000 spread on a $300,000-SDE business.

Is an HVAC business a good business to sell?

HVAC maps to the Service bucket, which sits at the low-risk end of the SBA charge-off ordering, so the financing a buyer needs is more likely to clear. The recurring maintenance book is a real value-mover when it transfers, and the final number still depends on how much the business runs without you.
