There are roughly 105,000 HVAC companies in the United States. Every year, only a tiny fraction end up on BizBuySell or with a broker. The rest — the vast majority — just quietly fade out when the owner gets tired. Those are your deals.
Go search BizBuySell right now for HVAC businesses in your metro area. I’ll wait.
What you’ll find: three to five listings, most asking $1.5M to $4M, most requiring $300K–$800K down, and every single one already being circled by a private equity roll-up with a checkbook you’ll never match. If you’re a licensed tech with ten years of experience and $100K saved up, you’re looking at those listings and thinking the same thing every first-time buyer thinks: I can’t afford to buy an HVAC company.
You’re wrong. You just can’t afford to buy the ones that are listed.
Here’s the number that should change how you think about this: roughly 80% of small businesses in the U.S. never sell. They don’t close because they failed. They close because the owner retired, got sick, got tired, or simply couldn’t find a buyer. The business wasn’t worth enough, wasn’t clean enough, or wasn’t structured well enough for any broker to take the listing.
In HVAC specifically, ACHR News has reported extensively on why these companies fail to sell: owner-dependent operations, messy books, no transferable systems. Brokers won’t touch them. PE doesn’t know they exist. The only person who can buy these businesses is someone who already knows how to run them.
That’s you.
What Makes an HVAC Company “Unsellable”
Let’s be specific. An “unsellable” company isn’t broken. It’s just not packaged. Here’s what they look like:
- The owner IS the contractor’s license. In many states, the business literally cannot operate without this person. No buyer who isn’t already licensed can step in.
- Customer relationships live in the owner’s phone. No CRM. No marketing. Twenty years of maintenance agreements exist as verbal promises and a shoebox of index cards.
- The books are a disaster. QuickBooks hasn’t been reconciled since 2019. The owner’s truck, his cell phone, his kid’s summer job salary, and his lake house insurance are all running through the business.
- One to three employees, max. Often just the owner and a helper. Maybe a part-time office person who’s the owner’s spouse.
- Revenue between $300K and $1.2M. Too small for PE. Too small for most brokers (who need a $50K–$100K commission to bother). Too big for the owner to just walk away from without feeling the loss.
- No formal processes. Dispatch is a whiteboard. Invoicing is “when I get around to it.” Warranty tracking doesn’t exist.
Valuation data from industry sources confirms what you’d expect: a clean, well-documented HVAC company with transferable systems sells for 4x–8x SDE. A company with the characteristics above? If it sells at all, it’s going for 1.5x–2.5x SDE. Usually closer to 1.5x.
That’s the gap you’re stepping into.
Why You — Specifically You — Are the Only Buyer Who Works
This isn’t motivational fluff. It’s structural economics.
A private equity firm buying HVAC companies needs to install a general manager, maintain licensing through a qualifying individual, build systems from scratch, and integrate the company into a platform. That costs $150K–$250K in overhead before they make a dime. For a $600K-revenue company clearing $120K in SDE, the math doesn’t work for them. They need companies doing $2M+ to justify the acquisition overhead.
A broker needs a sellable company to earn their commission. If the business requires a full owner dependency assessment just to figure out whether it can survive the transition, the broker isn’t taking the listing. It’s too much work, too uncertain, and the commission on a $180K deal doesn’t pay the bills.
But you? Here’s what you bring:
- You already have the license. You can step in on day one. No qualifying individual needed. No licensing gap during transition.
- You know the work. You don’t need to hire a service manager to figure out whether a compressor replacement is worth $4,200 or $6,800. You know.
- You can be the operator. The thing that makes these companies unsellable — that they require the owner to run every call — is the thing you’ve been doing for someone else for a decade.
- You don’t need the systems to already exist. You’re going to build them anyway. A messy company is a discount, not a disqualifier.
The seller has zero other buyers. Read that again. Zero. That changes every aspect of the negotiation.
How to Find Companies That Don’t Know They’re for Sale
These deals aren’t listed anywhere. You have to go find them. Here’s where to look, ranked by effectiveness.
1. Supply house relationships
This is the single best lead source, and most first-time buyers overlook it.
Your local Johnstone, Ferguson, or Winsupply counter guys know every contractor in the area. They know who’s slowing down, who’s ordering less, who’s been complaining about wanting to retire. They know who’s 65 and still dragging himself in to do duct work.
- Build genuine relationships at two or three supply houses. Don’t walk in and say “know anyone selling?” — that gets you nothing.
- Instead: “I’m looking to own my own shop in the next year or two. If you hear of anyone thinking about winding down, I’d love an introduction.”
- Repeat this every few weeks. Stay top of mind. When a counter guy mentions that Old Jim hasn’t been in much lately, follow up.
2. Trade association networking
Your state HVAC association, local ACCA chapter, or mechanical contractors association is a room full of aging owners. Go to the meetings. Most first-time buyers don’t, which means you’ll stand out instantly.
- Attend at least two meetings before you start asking around. People need to see your face before they’ll trust you with a referral.
- The most valuable people in the room aren’t the owners — they’re the insurance agents, accountants, and attorneys who serve multiple HVAC companies. They know who’s ready to exit.
3. Direct outreach to aging license holders
This takes more work, but it’s highly targeted.
- Your state licensing board has a public database of licensed contractors. In most states, it includes the licensee’s name and business address.
- Filter for contractors licensed 20+ years ago. Cross-reference with Google — if their website hasn’t been updated since 2015 and their Google reviews stopped in 2021, that’s a signal.
- Send a short, respectful letter. Not a mass mailer. A personal note: “I’m a licensed HVAC technician looking to buy a small company in [area]. If you’ve ever considered stepping back, I’d be happy to have a conversation over coffee.”
- Response rate on targeted direct mail to retiring owners: 3%–5%. That sounds low until you realize you only need one.
4. Your own employer
Seriously. If your boss is over 55 and has no obvious succession plan, you might be sitting inside your best deal. Read the full off-market deal sourcing playbook for how to approach this without blowing up the relationship.
5. Retirement and closing announcements
Google Alerts for “[your city] HVAC retiring” or “[your city] HVAC closing.” Check local Facebook contractor groups. Watch for patterns: the company that stops running Google Ads, the van that disappears from your neighborhood, the competitor whose phone now goes to voicemail.
How to Evaluate a Company Without Clean Books
Here’s where most first-time buyers panic. The owner hands you a QuickBooks file that looks like a crime scene, and you think you can’t evaluate the business.
You can. It just takes different tools.
Bank statement analysis
This is the gold standard for messy companies. Forget the P&L. Go straight to the bank statements.
- Request 24 months of business bank statements. If the owner resists, that’s a red flag — but most will hand them over once they understand you’re serious.
- Total all deposits. That’s your real revenue number. Every dime that came in the door shows up here, regardless of what QuickBooks says.
- Total all outflows. Separate them into categories: payroll, materials, rent/mortgage, insurance, vehicle expenses, personal draws.
- The full methodology is in the bank statement revenue verification guide.
Tax return reconstruction
The owner’s personal and business tax returns (Schedule C or 1120-S) give you a second data point. The IRS numbers won’t match the bank statements perfectly — but they should be in the same neighborhood. If the gap is huge, you’re either looking at cash payments not being reported (common) or expenses being inflated (also common).
Request three years of tax returns. Calculate SDE from each year. If SDE is trending down, you need to understand why.
Ride-along days
This is something you can do that no PE analyst or business broker ever would: spend a day in the truck.
- Ask the owner if you can ride along for two or three days. Position it as “getting a feel for the customer base.”
- What you’re actually doing: counting jobs, estimating ticket sizes, watching the owner interact with customers, gauging whether those customers will stay when the name on the truck changes.
- Pay attention to the phone. How many calls come in? How many does the owner answer personally? How many go to voicemail?
- Note which customers call the owner by first name. Those relationships need a transition plan.
The owner dependency gut check
After your ride-alongs, ask yourself one question: if this owner disappeared tomorrow, how many customers would call back next week?
If the answer is “most of them would just Google a new company,” the customer base has low transferability and the business is worth less. If the answer is “they’d call whoever answered the old number,” the business has real value independent of the owner. Run the full owner dependency assessment before you make an offer.
How to Structure the Deal When You’re the Only Buyer
The seller’s negotiating position is weak, and you should use that — respectfully. This isn’t about squeezing a retiree. It’s about structuring a deal that works for both sides when traditional financing won’t apply.
Pricing: 1.5x–2.5x SDE
For unlisted, owner-dependent HVAC companies in the $300K–$1.2M revenue range, market data from Axial confirms that actual transaction multiples land well below the 4x–6x numbers brokers advertise. Your starting offer should be in the 1.5x–2x range, with room to go to 2.5x if:
- The customer base is genuinely transferable (maintenance contracts, commercial accounts)
- The equipment fleet is in decent shape
- There’s at least one employee worth retaining
- Revenue has been stable or growing for three years
On a company doing $800K in revenue with $160K in reconstructed SDE, that’s a purchase price of $240K–$400K. That’s a real number for a tech with $100K in savings.
Seller financing is your primary tool
The seller has no other buyer. Banks won’t finance a company with books this messy. Which means the seller either finances the deal or closes the business and walks away with the value of the trucks and equipment at auction — maybe $40K–$60K.
Full seller financing is not only possible here, it’s the most common structure for these deals. Here’s what it typically looks like:
- 10%–20% down payment ($24K–$80K on our example deal)
- 5–7 year note at 5%–7% interest
- Monthly payments tied to the historical cash flow of the business (the seller knows what the business can support — use that)
- Personal guarantee from you (the seller will want this; it’s reasonable)
The consulting agreement
Build a 6–12 month consulting agreement into the deal. The seller stays on part-time (10–15 hours per week) to:
- Introduce you to every customer personally
- Transfer vendor relationships
- Handle the licensing transition in states where there’s an overlap period
- Answer the phone for the first 90 days so existing customers hear a familiar voice
Pay for this separately — $2,000–$4,000 per month is typical. It’s the cheapest insurance you’ll ever buy.
Earnout for disputed value
If you and the seller can’t agree on price, an earnout bridges the gap. Structure it simply:
- Base purchase price at your 1.5x–2x number
- Additional payments of 10%–15% of revenue above a baseline for 12–24 months
- Cap the total earnout so your maximum exposure is defined
This lets the seller believe in the upside while you pay only for value you actually receive.
License transition
This is HVAC-specific and critical. In most states, you’ll need to:
- Confirm your license covers the same classifications the seller’s business operates under
- File a change of qualifying individual with the state licensing board
- Update the business’s contractor license (or issue a new one under your entity)
- Coordinate timing so there’s never a gap in license coverage — even one unlicensed day can void insurance coverage on active jobs
Work with your state board directly. Timeline varies from two weeks to three months depending on the state.
The Advantage Nobody Talks About
Here’s what makes this whole strategy work, and why it’s not available to the PE firms or the MBA types searching broker listings:
You are the product.
In a company where the owner IS the business, the only viable buyer is someone who can BE the business. You have the license. You have the skills. You have the customer-facing credibility. When Mrs. Patterson calls because her furnace is making that noise again, and you show up in the same truck with the same tools and fix it the same way Jim did for twenty years — she doesn’t care that the name on the invoice changed.
Private equity can’t do this. They have to hire someone like you — and that someone has no reason to work for PE wages when they could own the company themselves.
Brokers can’t sell this. The companies are too small, too messy, too dependent on one person.
You’re the only buyer who works. And because you’re the only buyer, you set the terms.
That’s not a disadvantage of being a small buyer. That’s the entire advantage.
Your 6-Month Search Plan
Here’s a realistic timeline from “I’m ready to look” to “I’m negotiating a deal.”
Month 1: Build your search infrastructure
- Get pre-qualified with one SBA lender (even if you end up doing seller financing, it’s good to know your ceiling)
- Identify three supply houses where you’ll build relationships
- Join your state HVAC trade association if you’re not already a member
- Pull your state licensing board’s contractor database
- Set up Google Alerts for HVAC retirements and closings in your area
Month 2–3: Start conversations
- Visit each supply house weekly. Ask casual questions. Buy the counter guy coffee.
- Attend one trade association meeting or event per month
- Send 15–20 personalized letters to aging license holders
- Talk to your accountant and attorney about your target deal structure
- If your current employer might be a prospect, read the negotiating with retiring owners guide before saying anything
Month 4: Evaluate opportunities
- By now you should have 2–5 warm leads — owners who are at least willing to talk
- Request bank statements and tax returns from anyone who’s serious
- Schedule ride-along days
- Run your owner dependency assessment and bank statement analysis on each prospect
Month 5: Make your offer
- Draft a Letter of Intent on your best prospect
- Engage an attorney to review the deal structure
- Begin formal due diligence (60-day window is standard)
- Negotiate seller financing terms
Month 6: Close or recycle
- If diligence checks out, close the deal
- If it falls apart, go back to your pipeline. The leads you built in months 2–3 are still there.
- Don’t force a bad deal. There are always more retiring HVAC owners than there are qualified buyers.
The Math, One More Time
Broker-listed HVAC company: $2M asking price, $400K down, competing against PE. You lose.
Unlisted, owner-dependent HVAC company: $300K purchase price, $50K down, seller-financed, zero competition, and a seller who’s grateful someone showed up. You win.
The best HVAC acquisition you’ll ever make won’t be listed anywhere. It’ll be sitting in the cab of a ten-year-old Sprinter van, driven by a 63-year-old guy who’s been meaning to retire for three years and has no idea what to do with his business.
Go find him. You’re the only one who will.
