The Consolidators at Your Back Door
In 2024 the number of HVAC business sales jumped to fifty-five transactions, up roughly 72 percent from the year before, by Capstone Partners' count. By the middle of 2025 the market had already logged seventy-seven services deals, and private equity firms or their platforms were behind more than half of them. S&P Global Market Intelligence clocked add-on acquisitions of HVAC services companies rising about 88 percent year over year. The share of deals done by private equity went from 8 percent in 2023 to 23 percent in 2024. If you own an HVAC company doing real revenue, a buyer has probably already found your name.
I have sat across from owners who got the letter. A firm they've never heard of, backed by capital they can't quite trace, asking for a call about their business. Some are flattered, some are offended, and most have no idea whether the number that follows will be serious. It usually is. What they're being asked to sell into is a roll-up, and it helps to understand the machine before you decide whether you want to be part of it.
Who is actually buying
The strategy is old and it works. A private equity firm buys one solid contractor, calls it the platform, and then buys smaller companies around it as add-ons, or tuck-ins. Each tuck-in gets folded into the platform's back office, its buying power, its software. The platform grows, the blended multiple rises, and the whole thing gets sold years later to a larger fund for more than the sum of the parts.
The pace has been remarkable. By early 2026 one Apollo-backed platform, Apex Service Partners, had reportedly rolled up more than a hundred brands and closed something like sixty add-ons in 2025 alone. That isn't a company buying competitors. It's a buying operation that happens to own HVAC companies, and there are several of them working the same territory.
For an owner in the two-to-hundred-million range, that math cuts two ways. The demand for good contractors has pushed prices up, so a well-run business is worth more today than it was 5 years ago. But the consolidators are also going to be your competitor for technicians, for acquisitions, and eventually for customers, whether or not you ever sell to one.
What makes you a platform, not a tuck-in
Here's the distinction that decides your price. The tuck-ins get bought cheap, because they bring a crew and a customer list and not much else. The platforms get bought rich, because they bring a business that runs without heroics.
The difference is boring, and it's exactly what the price turns on. A recurring service base, because contracted revenue is what a financial buyer underwrites. A management layer that isn't you, so the business doesn't walk out the door when you do. Clean books that survive a diligence process looking for one honest number. Systems a buyer can plug into instead of rebuild. A shop with those things is a platform, or a premium tuck-in, and it names a price closer to the high end of the range. A shop that's really just the owner and a good reputation is a cheap add-on no matter how busy it is.
You don't have to sell to benefit from building those things. Every item on that list makes the company worth more, run better, and less dependent on you, which is worth having whether the exit is a consolidator, a competitor, your kids, or no one at all. The consolidators didn't invent value. They just pay the most for it, and they're paying right now.
So decide on purpose. If you might sell in the next few years, spend that time making yourself a platform rather than a tuck-in, because the gap between those two prices is measured in multiples, not percentages. If you're not selling, build the same way, because the thing that earns the premium is the same thing that lets you take a month off without the phone following you. Either way, don't let the first serious letter be the day you start thinking about what your business is actually worth.
