What Multiple Do HVAC Companies Sell For?

If you own an HVAC company and you've started researching what it might be worth, you've probably seen multiples ranging from "2x earnings" to "11x EBITDA" and wondered what on earth is going on. That range isn't wrong — it's just reflecting the enormous gap between what a small owner-operator shop sells for versus what a PE-backed platform acquisition commands.

Let me break down exactly where your HVAC company falls in that spectrum and what you can do about it.

The Three Tiers of HVAC Valuations

Tier 1: Owner-Operator Shops (Under $3M Revenue)

If you're the owner and you're also the one showing up to install furnaces on Saturday morning, you're in Tier 1. Your buyer is probably another HVAC tech who wants to own their own business instead of working for someone else.

These shops sell for 2.0-3.5x SDE. Your SDE is typically everything you take home from the business — salary, truck, health insurance, cell phone, whatever you run through the company. For most owner-operated HVAC shops doing $1-3M in revenue, SDE runs $200K-$500K, which means sale prices of $400K to $1.75M.

The buyer at this level is typically financing through an SBA 7(a) loan, which means the bank needs to see that the business can service the debt AND pay the new owner a living wage. That math caps what they can afford to pay.

Tier 2: Established Companies ($3M-$15M Revenue)

This is where things get interesting. You've got a service manager, a dispatcher, maybe 10-20 technicians, and you're not the one crawling through attics anymore. You've built something that runs without you being on every job.

These companies sell for 3.5-5x SDE or 5-8x EBITDA. The jump in multiples comes from a bigger buyer pool — you're now attracting not just individual buyers but also larger HVAC companies looking to expand and PE firms looking for "add-on" acquisitions to bolt onto their existing platforms.

At $5M revenue with $750K EBITDA, your company might sell for $3.75M to $6M. That's a meaningful number — and it's achievable for a well-run mid-size HVAC operation.

Tier 3: PE Platform Deals ($15M+ Revenue)

The top of the market. Private equity firms like Wrench Group, Apex Service Partners, and Horizon Service Partners are building national HVAC platforms by acquiring companies exactly like yours. (Here's a detailed look at what PE firms screen for in small business acquisitions.) Platform acquisitions — where a PE firm buys your company as the foundation for a regional roll-up — command 8-11x EBITDA.

At $15M revenue and $2.5M EBITDA, that's $20M-$27.5M. These are life-changing numbers, and they explain why every HVAC owner with a sizable company has been getting unsolicited calls from private equity groups for the last five years.

The One Thing That Matters More Than Anything Else

I've analyzed thousands of HVAC transactions and one factor consistently separates high-multiple companies from low-multiple companies: recurring maintenance contracts. (If you want the full data on why, see our analysis of how recurring revenue increases business value by 20-40%.)

An HVAC company where 40% of revenue comes from maintenance agreements — those $15-25/month service contracts where you show up twice a year for tune-ups — sells for materially more than an identical company that relies on emergency calls and new installations.

Here's why buyers love maintenance contracts:

• Predictable monthly revenue. The buyer can model exactly what January cash flow looks like before they've made a single service call.
• Higher customer lifetime value. A maintenance customer spends 2-3x more over their lifetime because you're the first call when something breaks.
• Built-in equipment replacement pipeline. You're inspecting systems twice a year. You know which furnaces and ACs are nearing end-of-life. That's a sales pipeline no one else has.
• Lower customer acquisition cost. Keeping a maintenance customer costs almost nothing compared to acquiring a new one through advertising.

I've personally seen HVAC companies with strong maintenance programs sell for 1.5-2x more than comparable companies without them. If you do nothing else before selling, build your maintenance contract base.

What Else Drives HVAC Multiples Up (or Down)

Technician retention is probably the second most important factor. The HVAC technician shortage is real and getting worse. If you've got 12 certified technicians who've been with you for 5+ years, that workforce is incredibly valuable. If you're constantly hiring and training replacements, buyers see a treadmill they don't want to get on.

Residential vs. commercial mix affects valuation differently than most owners expect. PE buyers generally prefer residential because it's more fragmented (easier to consolidate) and maintenance contracts are easier to sell. Commercial HVAC is lumpy — big projects create revenue volatility that makes buyers nervous. A 70/30 residential/commercial split is the sweet spot.

Geographic density is something buyers obsess over that owners rarely think about. A company with 500 maintenance customers within a 15-mile radius is worth more than one with 500 customers spread across a 60-mile territory. Dense service areas mean more calls per truck per day, lower fuel costs, and faster response times. PE buyers specifically model route density when evaluating acquisitions.

Owner dependency shows up in HVAC companies differently than in professional services. The question isn't whether the owner does the technical work (hopefully they stopped years ago) — it's whether the owner manages every customer complaint, approves every estimate, and makes every hiring decision. If you've built a service manager and office manager who handle 90% of daily decisions, your company is worth more. If everything still flows through you, buyers see risk.

How to Jump From One Tier to the Next

The biggest valuation gains come from crossing tier boundaries. Going from 2.5x SDE to 6x EBITDA doesn't require doubling your revenue — it requires changing the type of buyer who's interested in your company.

From Tier 1 to Tier 2: Hire a service manager. Stop running calls yourself. Build maintenance contracts to 25%+ of revenue. Get your financials CPA-reviewed. These changes take 12-18 months but can increase your valuation by 50-100%.

From Tier 2 to Tier 3: This is harder and usually involves acquisitions of your own. PE firms want $15M+ revenue platforms, so you may need to acquire 2-3 smaller HVAC companies to reach that threshold. But the multiple arbitrage is powerful — you buy small companies at 3x and sell the combined entity at 8-10x.

The Market Right Now

HVAC remains one of the hottest sectors in home services M&A. PE firms have deployed billions into the space, and the consolidation wave is far from over. Demographic trends (aging HVAC systems, new construction, heat pump adoption) support long-term demand, and the technician shortage creates natural barriers to entry that protect established companies.

That said, multiples have compressed slightly from 2021-2022 peaks as interest rates rose and PE returns came under scrutiny. The market is still strong, but it's more discriminating. Well-run companies with recurring revenue and strong teams still command premium multiples. Undifferentiated shops with no maintenance contracts and high owner dependency are seeing lower offers than they would have two years ago.

If you're thinking about selling in the next 2-3 years, the window is still excellent. But don't wait for the market to do the work — invest in the things that actually move your multiple: maintenance contracts, technician retention, and management depth.
