How to Sell Your HVAC Business to Private Equity

Your phone rings. It's a guy from a PE-backed HVAC platform you've never heard of. He tells you they love your market, admire what you've built, and want to "explore a conversation about partnership." He asks if you'd be open to a meeting.

This is happening to HVAC owners across the country right now. Private equity has been aggressively consolidating residential and commercial HVAC for the past five years, and the pace is accelerating. If you're doing $3M+ in revenue with a real maintenance book, you are on somebody's target list. The question isn't whether you'll get a call — it's whether you'll be ready when it comes.

Why PE Is Obsessed With HVAC

To negotiate effectively, you need to understand what's driving the buyer. PE firms aren't buying your trucks and inventory. They're buying three things: recurring maintenance contracts, local market density, and technician headcount in a labor-starved industry.

The playbook is straightforward. A PE firm acquires a "platform" company — usually $10M-$30M in revenue with professional management — at 7-10x EBITDA. Then they bolt on smaller operators at 4-6x EBITDA, centralize back-office operations, negotiate better equipment pricing through volume, cross-sell services, and sell the combined entity in 3-5 years at a higher multiple than they paid. The spread between what they pay you and what they eventually sell for is where they make their money.

This math only works if they can buy enough quality operators at reasonable prices. That's why your phone is ringing.

How to Evaluate an Unsolicited Offer

The first rule: an unsolicited offer is a starting point, not a finish line. The person calling you is paid to buy companies as cheaply as possible. Their initial "indication of interest" is designed to anchor the conversation low while making you feel flattered.

When I advise HVAC owners who receive these calls, I tell them to ask three questions before anything else.

First, is this a platform or add-on acquisition? Platform deals — where your company becomes the anchor of a new PE portfolio — command 7-10x adjusted EBITDA. Add-on deals, where you're being tucked into an existing platform, typically trade at 4-6x. The difference on a $1.5M EBITDA business is $4.5M-$6M in enterprise value. You need to know which category you fall into before you negotiate anything.

Second, what's the actual structure?A "$12 million offer" means nothing until you understand how much is cash at close versus earn-out versus rollover equity versus seller notes. I've seen HVAC deals where the headline number was $10M but only $6M was cash at closing. The rest was contingent on hitting revenue targets for three years while working for someone else.

Third, who is the actual buyer?Is it the PE fund directly, or the platform company they've already acquired? This matters because the platform company's management team will be running your business post-close. Meet them. Understand their integration plan. Talk to other owners they've acquired.

Platform vs Add-On: What Determines Your Category

Most HVAC owners want to believe they're a platform. Most aren't. Here's what actually separates the two.

Platform candidates typically have $10M+ in revenue, a management team that can operate without the owner, multiple service lines (install, maintenance, commercial, residential), a strong brand in their metro area, and clean financials with at least $1.5M in EBITDA. If the business falls apart when you go on vacation, you're not a platform.

Add-on candidates are $3M-$10M in revenue, owner-operated, strong in a specific niche or geography, and valuable primarily for their customer base and technicians. There's absolutely nothing wrong with being an add-on — the multiples are lower, but the deals are often simpler, faster to close, and require less post-closing involvement.

The gray area is $8M-$15M. At this size, you could go either way depending on the buyer's strategy. If you're in this range, how you position the business matters enormously.

Running a Competitive Process

The single biggest mistake HVAC owners make is engaging exclusively with the first buyer who calls. I cannot overstate this: a competitive process will increase your sale price by 20-40% compared to a bilateral negotiation with one buyer.

There are currently 50+ PE-backed HVAC platforms actively acquiring in the US. If one of them wants you, others probably do too. A good M&A advisor will approach 15-25 qualified buyers simultaneously, create urgency through a structured timeline, and let the market tell you what your business is worth.

I watched an HVAC owner in the Southeast turn a $6M unsolicited offer into $9.2M through a competitive process — same business, same financials, just more buyers at the table. The original buyer ended up winning, but at a price they never would have offered without competition.

Cleaning Up Your Maintenance Contract Book

Your maintenance agreement portfolio is the single most valuable asset in a PE buyer's eyes. Recurring revenue trades at a premium to project-based or break-fix work because it's predictable. But not all maintenance contracts are created equal, and PE buyers will scrutinize every detail.

Before going to market, audit your maintenance book with these questions. What percentage of contracts are auto-renewing versus annual opt-in? Auto-renewing contracts are worth materially more. What is your annual retention rate? Anything above 85% is strong; below 75% is a red flag. Are contracts assignable without customer consent? Check the language — some older contracts have change-of-control provisions that could create problems.

Also look at pricing. Many HVAC owners haven't raised maintenance contract prices in years because they don't want to lose customers. PE buyers actually prefer this because it means there's an easy margin improvement opportunity post-close — they just raise prices 8-12% and lose maybe 3% of customers. But you should be the one capturing that margin, not them. Raise your prices 12-18 months before going to market.

Earn-Outs: Negotiating What Comes After Close

Nearly every PE deal for an HVAC company includes some form of contingent consideration — money you receive only if certain targets are met after closing. This is where deals get complicated and where owners get burned if they're not careful.

The typical structure is 70-80% cash at close and 20-30% as an earn-out tied to revenue or EBITDA targets over 1-3 years. Some deals also include "rollover equity" where you retain 10-20% ownership in the combined platform, which you cash out at the second sale.

Here are the earn-out terms I fight hardest on for HVAC clients.

• Revenue targets over EBITDA targets.You can control revenue. You cannot control EBITDA after the buyer starts allocating corporate overhead to your P&L. I have seen buyers allocate $400K in "management fees" to an acquired business, tanking EBITDA and killing the earn-out. Insist on revenue-based milestones.
• Defined accounting methods. The earn-out agreement must specify exactly how revenue and EBITDA will be calculated, including what expenses can and cannot be allocated. Get this in writing with examples.
• Operational autonomy during the earn-out period.If the buyer can cut your marketing budget, reassign your techs to other markets, or change your pricing — and then hold you to the same targets — you're set up to fail. Negotiate specific protections.
• Acceleration clauses.If the platform is sold during your earn-out period (which happens more often than you'd think), your earn-out should automatically pay at the maximum amount.

What to Do Right Now

If you're an HVAC owner considering a sale in the next 1-3 years, start here. Get your financials cleaned up — three years of tax returns, a clear breakdown of maintenance versus install versus service revenue, and a list of every add-back you'd make to EBITDA. Audit your maintenance contracts. Document your technician roster with certifications, tenure, and compensation. And do not — I repeat, do not — sign an exclusivity agreement with the first buyer who flatters you over a steak dinner.

The HVAC M&A market is as hot as it's ever been, but it won't last forever. PE firms are running out of easy platform acquisitions and are increasingly competing on add-ons, which is pushing multiples up across the board. If you're going to sell, the next 18-24 months are likely your best window. But only if you approach it like a business transaction, not a handshake deal.
