What Is My HVAC Business Worth?

Mike had a number in his head—the figure he'd been carrying around for years, the one he expected to walk away with when the time finally came. 

It was built on a rough read of his revenue, conversations with other owners at trade events, and honestly, what he felt he'd earned after 22 years of early mornings and emergency calls.

When he finally sat down with an advisor and worked through an actual valuation, the number looked different. Not worse in one way; it came out better than he'd expected. But the method behind it was nothing like how he'd been calculating it all along.

If you're asking what your HVAC business is worth, the honest answer is that it depends on things most owners have never thought to measure. Here's how it actually works.

The Number Buyers Start With: EBITDA

Here's something most owners don't realize going in: buyers don't care much about your revenue. 

What they actually want to know is how much cash the business generates, and for that, they use a number called EBITDA, which stands for "earnings before interest, taxes, depreciation, and amortization." It's basically your profitability with all the financial noise removed.

To get there, they start with your net income and work backwards, adding back interest, taxes, depreciation, and amortization. Then they look at things like whether you're paying yourself above what a hired manager would cost or whether any personal expenses are running through the business. After all those adjustments, you get what's called adjusted EBITDA, and that's the number your valuation is built on.

The add-backs can actually work in your favor. 

Say you're paying yourself $300,000 a year, but replacing you with a GM would cost $120,000. That $180,000 gap adds back to your EBITDA. Same goes for the truck that's technically a business expense but mostly sits in your driveway on weekends. 

None of this is unusual for buyers; expect it. You just need to have it documented, because anything you can't back up on paper, they'll ignore.

How the Multiple Gets Applied, and What Moves It

Once buyers have your adjusted EBITDA, they multiply it by a number to arrive at a purchase price. For HVAC businesses in the $1–5M revenue range, that multiple has historically landed somewhere between 4x and 7x, though it shifts depending on your recurring revenue, growth trend, how dependent the business is on you, and what the M&A market looks like at the time. Businesses with stronger recurring revenue and cleaner operations can push above that range.

The multiple isn't something buyers just pick out of thin air. It reflects how they feel about the risk and opportunity in your specific business. A few things that tend to move it upward:

1. Recurring revenue

Maintenance agreements and service contracts make buyers feel a lot better about what they're buying. When 40% of your revenue is already locked in at the start of the year, that's a very different business from one where every dollar has to be chased down month after month.

2. Growth trajectory

A business that grew 15% last year tells a story. Even slow, steady growth is reassuring, and it means demand is real and you're capturing it.

3. Geographic position

Being in a high-growth market, or being the established player in a geography a buyer wants to break into, adds a layer of strategic value that goes beyond the financials.

4. Operational independence

This one comes up more than owners expect. The more the operation can run without you in the middle of every decision, the more confident a buyer feels about what happens after you leave, and that confidence shows up in the multiple.

What Pulls the Multiple Down

Understanding what hurts your multiple is just as important as knowing what helps it, because buyers are fundamentally trying to figure out one thing: how much risk am I taking on here?

Customer concentration is one of the most common issues that comes up. If a single commercial account is responsible for 25% of your revenue, that's a dependency that makes buyers uncomfortable and rightfully so. 

One relationship walking out the door after the sale could meaningfully change the financial picture they thought they were buying. They'll factor that uncertainty into what they offer.

Owner dependency is another one that catches people off guard. If your techs are calling you for quotes, if customers request you specifically, or if you're the one who built and maintains the key vendor relationships, all of that is transition risk in a buyer's eyes. They need to believe the revenue doesn't leave when you do.

And then there are the financials. Disorganized records, undocumented add-backs, and revenue that swings year to year without a clear explanation. These things don't just slow the process down; they give buyers a reason to doubt what you're telling them. Whatever they can't verify, they'll either discount or ignore it entirely. It's not that they assume the worst; it's just that they can only pay for what they can see.

The Part Most Owners Miss: Timing Affects Value

Your business doesn't have a fixed value; it has a value at a point in time, in a specific market environment, with a specific buyer profile. 

HVAC businesses sold during active M&A periods, when multiple buyers are competing for deals, consistently come away with better multiples than identical businesses sold quietly to a single buyer with no pressure to move. That's not a coincidence. Competition changes the dynamic entirely.

This is why running a real process matters. When multiple buyers are looking at your business at the same time, they know it, and that changes how they behave. 

An advisor who knows how to create that environment isn't just handling paperwork; they're directly influencing what ends up in your pocket at closing.

What Mike Found Out About His Own Number

When Mike finally went through the process, his adjusted EBITDA came out higher than he'd expected. 

Not because the business had changed, but because he hadn't been factoring in his above-market salary or the personal expenses running through the company. 

Once those were added back, the picture looked different, better than the number he'd been quietly carrying around for years. The multiple he ended up with reflected his strong maintenance agreement base and the fact that there were active buyers in the market at the time. 

The final number wasn't what he'd been guessing at trade shows. It was better because by the time he went to market, he understood what he was actually selling and how to present it clearly.

If you want a rough starting point, our Ask NorthBase tool can give you a general sense of where your business might land. But the real number (the one that actually matters) comes from looking at your specific financials, your business profile, and who's actively buying in your market right now. That's a conversation worth having before you need to have it.
