What Is My HVAC Business Worth?

It's a number most HVAC owners carry around for years before they ever test it against reality. 

A rough figure based on revenue, something overheard at a trade show, maybe a story from another owner who sold. It feels solid enough until you're actually sitting across from a buyer and they start asking questions you weren't prepared for.

The honest answer isn't a single number. It's a calculation, and understanding how it works changes how you look at your own business.

How Buyers Actually Value an HVAC Business

Buyers don't price HVAC businesses on revenue. 

They price them on EBITDA (earnings before interest, taxes, depreciation, and amortization), and this is the number that reflects how much cash the business actually generates, stripped of financing choices, accounting decisions, and one-time items.

To get there, buyers start with your net income and add back interest, taxes, depreciation, and amortization. Then they go further, adjusting for owner compensation above what a hired manager would cost, personal expenses running through the business, and any non-recurring costs. 

The result is called adjusted EBITDA, and it's the foundation of your valuation.

For example, if you're paying yourself $300,000 a year but a replacement general manager would cost $120,000, that $180,000 difference adds back to your EBITDA. If your truck is technically a business expense but used personally, that comes back too. Add-backs are legal, expected, and common. 

They just need to be documented clearly.

The Multiple: What Moves It Up and What Pulls It Down

Once buyers land on your adjusted EBITDA, they apply a multiple. The multiple isn't fixed. It reflects how a buyer reads the risk and upside of your specific business.

Several things push it higher.

1. Recurring revenue. Maintenance agreements and service contracts make revenue predictable. A business where 40% of revenue is contracted looks fundamentally different from one where every dollar has to be re-earned each month.

   
   

2. Consistent growth. A business that's been growing signals that demand is there and the operation knows how to capture it.

3. Geographic positioning. If you're the dominant player in a market a buyer wants to enter, that carries strategic value.

4. Operational independence. The less the business depends on you personally, the more transferable it is. Buyers' price transferability. Just as important is understanding what buyers flag as risk because risk lowers multiples.

   
   

What Pulls the Multiple Down

Just as important as knowing what buyers want is understanding what makes them nervous because risk, real or perceived, lowers multiples.

1. Customer concentration is one of the most common issues. If a single commercial account drives a significant share of your revenue, buyers see a liability, not an asset. The question they're asking isn't whether that client is loyal to you. It's whether they'll stay after you leave. That uncertainty gets priced into the offer.

2. Owner dependency is the other major flag. If technicians call you for quote approvals, if clients ask for you by name, or if key vendor relationships exist because of your personal history with someone and that's transition risk. A business that runs through the owner doesn't transfer cleanly, and buyers discount accordingly. The more the operation can function without you in the room, the more it's worth.

3. Disorganized financials slow everything down and erode confidence. Unexplained revenue swings, add-backs that aren't documented, and records that require excavation to understand. All of it leads buyers to apply a discount to whatever they can't independently verify. 

   
   

Clean books don't just make the process easier. They signal that the business has been run professionally.

None of these are permanent problems. They're fixable. But they're much easier to address before you're in a process than during one.

What Mike Found When He Actually Ran the Numbers

Mike had been running his HVAC company for over two decades. He had a number in his head when he sat down with an advisor and calculated loosely from revenue and what he'd picked up from other owners over the years.

When they worked through his actual adjusted EBITDA, the number came out higher than he expected. He hadn't accounted for how much of his compensation was above market rate or for a handful of personal expenses that had been running through the business. His strong maintenance agreement base also reflected well when the multiple was applied.

The final number wasn't what he'd guessed at trade shows. It was better because he finally understood what he was actually selling.

Timing Changes the Number Too

Your business doesn't have a fixed value. It has a value at a point in time, in a specific market, with a specific buyer profile. Running a process that gets multiple buyers looking at your business simultaneously creates competition. Competition is what closes the gap between what a business is worth and what a buyer would prefer to pay.

An advisor who knows how to run that process adds real value at the closing table and not just in the weeks leading up to it.
