How to Increase HVAC Business Valuation Before You Sell

Two HVAC companies in the same city. Same revenue. Same trucks in the lot. One sells for four times earnings. The other sells for ten.

Nothing about the work is different. What's different got built in the three years before either owner ever called a broker.

Private equity is buying HVAC companies, and not quietly

Private equity, and not quietly. Eighteen US platforms have a disclosed HVAC acquisition on the record, and roughly twenty-seven are buying across HVAC, plumbing and combined residential trades — Alpine, Leonard Green, Goldman Sachs, GI Partners and OMERS standing behind names like Apex, Wrench, Sila, ARS and TurnPoint (CT Acquisitions roll-up tracker, 2026). Apex alone closed around sixty add-on acquisitions in a single year.

The share of HVAC deals going to private equity moved from 8 percent in 2023 to 23 percent in 2024 — Axial's own deal data, one year apart. That's not a trend anymore. That's the market.

It cuts both ways. There has never been a better time to sell an HVAC company. There has also never been a worse time to be the shop next door to one that just got bought, because a PE-backed competitor with real marketing money now shares your zip code.

The buyer isn't pricing your trucks

Not your trucks. Not your tenure. Not the plaque in the lobby.

Those are the published bands (Sofer Advisors, CT Acquisitions, 2026), and the honest read on them is that the spread inside each row is bigger than the gap between rows. What moves a shop up its own band, and then into the next one, is the same short list every time: recurring maintenance revenue, margins that hold, and a business that runs without the owner in it. On three million in earnings, that one line item swings what you walk away with by one and a half to four and a half million dollars.

The rest of the gap is you.

Owner dependence is a line in his risk memo

Because the buyer isn't buying a business that needs you. He's buying one that keeps running after you're gone, and he's underwriting the risk that it doesn't.

Every process living in your head is a line in his risk memo. You price the tricky jobs. You take the angry callback. You're the one who knows which tech to send to the difficult customer on the north side. None of that is proof you're good at this. To the person writing the check, it's proof the business is you wearing a company as a costume.

He'll still buy it. He'll buy it cheaper, and he'll structure it so a chunk of the price is an earnout you have to stay two years to collect. That's not him being difficult. That's him pricing the risk that the business walks out the door with you.

I spent years as the marketing director for a large business brokerage on the West Coast, and most of that work was with home services companies — HVAC, plumbing, the trades. My job was helping those owners automate the business so they could step out of the daily work and eventually sell it. That's where this stopped being theory for me. Stepping away isn't a decision you make the year you're ready to sell. It's a build, and it takes longer than anybody plans for. Which is the entire reason I'm telling you now instead of when you've already got a buyer at the table.

A shop that stops when you stop isn't a business. It's a job that pays better and sells for less.

Three moves for the next twenty-four months

Three things, in this order.

Turn one-off jobs into contracts. Maintenance agreements are the largest single lever on your multiple, and the only one that also makes the business better while you still own it — repeat contact, smoother scheduling, first call on the replacement.

Get out of the daily path. Not out of the business. Out of the path. Write down every decision that reached you personally last week and sort it by whether it needed judgment or just needed answering. The weekend test sorts that pile faster than any consultant will.

Answer every call, every time. In a market this short on labor, the fastest revenue in your business is the revenue already dialing your number. A call missed at five is a customer who booked somebody else by six.

Do this before you talk to anybody

Pull last year's numbers. Split revenue into recurring and one-off and be honest about which is which. Then count how many decisions reached you personally in the last month.

Those two numbers are your multiple. Not your revenue — the guy at four and the guy at ten had the same revenue.

You have two years to change them. The buyers aren't going anywhere.
