Most HVAC owners, when they think about selling, think about calling a business broker. Brokers are the default path — they list businesses, find buyers, and collect a commission (typically 8–12% on deals under $2M, 3–6% on larger deals). The whole process feels familiar: list, show, sell. It's how you'd sell a house.
But there's a meaningful gap between what a broker gets for an HVAC business and what a prepared seller who engages private equity buyers directly can achieve. The gap isn't random — it's structural. Brokers and PE buyers use different valuation methods, target different buyer pools, and operate in different price tiers. This post explains why, and how to think about which path is right for you.
How Business Brokers Value HVAC Companies
The standard broker valuation method for HVAC businesses is the SDE multiple — Seller's Discretionary Earnings. SDE starts with net profit and adds back everything the owner extracts from the business: owner salary, owner benefits, personal expenses run through the P&L (vehicle, phone, family salaries, gym memberships), depreciation, and any one-time items that won't recur.
The logic is straightforward: the buyer is purchasing the total economic benefit the owner is getting. They're not hiring a manager — they're buying a job. SDE captures what that job is actually worth before the purchase price is applied.
Typical SDE multiples in the HVAC broker market:
Individual owner-operators, SBA financing
Larger owner-ops, some local strategics
Brokers use SDE because it's the right metric for their buyer pool. That pool consists of individual operators, owner-operators taking on a second location, and local competitors looking to acquire customers — not PE. These buyers are financing with SBA loans, and SBA lenders underwrite on SDE. It's a functional, legitimate market for what it is.
For a deeper look at how SDE is calculated and where it diverges from EBITDA, see our SDE vs. EBITDA guide for HVAC owners.
How PE Buyers Value HVAC Companies
Private equity buyers don't use SDE. They use EBITDA — Earnings Before Interest, Taxes, Depreciation, and Amortization. The critical difference: EBITDA does not add back the owner's full salary. Instead, it normalizes compensation to a market-rate replacement cost.
If you pay yourself $200K and a competent general manager would cost $90K, EBITDA includes $90K in compensation expense — not zero. PE buyers aren't buying a job. They're buying a cash flow stream to bolt onto a larger platform that already has management infrastructure. Owner comp is a real ongoing cost in their model.
Typical PE multiples in the HVAC market:
Tuck-ins to existing PE platforms
Businesses that anchor new roll-ups
PE uses EBITDA because it standardizes comparison across portfolio companies. When a roll-up platform is evaluating 20 acquisition targets simultaneously, EBITDA is the common language. It strips out financing structure (interest) and non-cash charges (depreciation) to get to clean operating earnings.
The PE engagement threshold matters: most PE buyers won't engage below ~$1M EBITDA. Their fund economics require deal sizes large enough to justify the transaction cost. Below that threshold, brokers are often the only realistic path. Above it, the difference in outcome can be 40–80% in favor of a PE process.

Broker vs. PE: Side-by-Side Comparison
| Factor | Business Broker | Private Equity |
|---|---|---|
| Valuation method | SDE multiple | EBITDA multiple |
| Typical multiple | 2x–4x SDE | 4x–7x EBITDA |
| Buyer type | Individual operators | Roll-up platforms |
| Best for | <$1M EBITDA businesses | $1M+ EBITDA businesses |
The Information Gap Most Sellers Don't Know Exists
The problem most HVAC sellers face isn't that they chose the wrong path — it's that they didn't know there were two paths. A broker will take any listing. A broker who specializes in small business sales may have never personally closed a PE deal. They're not hiding the PE market from you; they just don't operate in it.
The add-backs distinction creates a subtle trap. A broker uses gross add-backs to maximize SDE — that's correct and appropriate for the SBA buyer market. PE buyers use EBITDA and scrutinize add-backs carefully. Every add-back has to be documented, justified, and likely to survive a Quality of Earnings review. The PE add-back process is more rigorous — but PE also applies a materially higher multiple. For businesses with $1M+ in normalized EBITDA, the net effect almost always favors PE.
How do you know if you're in PE territory? Four signals:
Revenue above $3M
Most PE platforms are looking for businesses in the $3M–$15M revenue range as tuck-in acquisitions. Below $3M, the EBITDA rarely clears the PE engagement floor.
EBITDA above $800K–$1M
The PE engagement threshold. Below this, PE firms pass on deal economics. Above it, you'll typically see competitive interest from multiple platforms.
Recurring service contracts above 30% of revenue
PE buyers underwrite recurring revenue at a premium. Maintenance agreements signal predictable cash flow, lower churn risk, and customer lifetime value — all of which justify higher multiples.
Not owner-dependent
If the business can operate without you for two consecutive weeks, PE will engage. If you're the primary technician, dispatcher, and account manager, key-man risk will suppress any multiple you're offered.

Calculate Your Valuation →Should You Use a Broker or Go Direct to PE?
This is the practical question, and the answer depends almost entirely on your EBITDA. Here's the decision framework:
Broker is likely the right path
PE won't engage below this threshold — their fund economics don't support the transaction cost on smaller deals. A broker's SBA-financed buyer pool is the realistic market. A good broker with HVAC experience will get you fair value.
Hybrid — M&A advisor territory
A skilled M&A advisor (not a generalist broker) can run a process that reaches both PE buyers and strategic acquirers simultaneously. Competitive tension between buyer types is what drives you to the top of the range. A generalist broker may not have the PE relationships to run this process.
PE is your primary market
At this scale, PE roll-up platforms are actively looking for businesses like yours. A generalist broker may actually underserve you here — they may not know how to run a competitive PE auction or prep a CIM for institutional buyers. An M&A advisor with HVAC sector experience is the right hire.
M&A Advisors vs. Business Brokers: The Distinction Matters
These aren't the same thing, and understanding the difference is important before you hire anyone:
Business Broker
- Success fee only (8–12% on deals under $2M)
- Works with individual buyers and SBA lenders
- Smaller deals ($500K–$3M typical range)
- May not run competitive PE auction processes
M&A Advisor
- Retainer + success fee (2–5% on deals $5M+)
- PE firms, strategics, family offices in buyer pool
- Larger transactions ($5M+ enterprise value)
- Runs structured competitive auction processes

Frequently Asked Questions
Do I need a business broker to sell my HVAC company?
Not necessarily. For businesses with EBITDA below $800K, a broker is typically the most practical path — their SBA-financed buyer pool is the realistic market. For businesses with EBITDA above $1M–$1.5M, engaging PE buyers directly (or through an M&A advisor who runs competitive processes) often yields materially better outcomes. A generalist broker may not have the PE relationships to run the process that gets you the best price at that scale.
What's the difference between SDE and EBITDA for HVAC valuation?
SDE adds back the owner's full salary and personal expenses to net profit — it captures total owner benefit. EBITDA normalizes owner compensation to a market-rate replacement cost, not zero. SDE produces a higher earnings base but carries a lower multiple (2x–4x). EBITDA produces a lower base but is used by PE buyers who apply higher multiples (4x–7x). For businesses above $1M in earnings, EBITDA math typically yields a significantly higher valuation.
At what EBITDA does PE become interested in HVAC businesses?
Most private equity roll-up platforms have a floor of approximately $1M in EBITDA before they'll engage on a standalone acquisition. Some will look at $800K for tuck-ins into existing markets. Below those thresholds, PE firms pass — their fund economics don't support the transaction costs on smaller deals. At $1M+ EBITDA, multiple PE firms will typically compete, which is what drives the multiple premium over broker-facilitated deals.
How much does a business broker charge to sell an HVAC company?
Business brokers typically charge 8–12% commission on deals under $2M and 3–6% on larger transactions. They work on success fee only — no upfront retainer. M&A advisors (who focus on deals above $5M and run competitive PE processes) typically charge a small upfront retainer plus a 2–5% success fee. The distinction matters: a broker's network is individual buyers and SBA lenders; an M&A advisor's network includes PE firms and institutional buyers.
Know Which Market You're In Before You Call Anyone
Brokers and PE buyers are not competing for the same deals — they serve different markets. A broker who's great at selling a $1.2M HVAC business to an owner-operator is not the right person to run a competitive PE auction for a $5M enterprise value deal. And a PE firm that only looks at $1M+ EBITDA deals isn't the right call for a business that hasn't cleared that threshold yet.
Knowing which category your business falls into before you start the sale process is the single most important piece of information you can have. It tells you which advisor to hire, which buyer pool to target, and whether your current EBITDA puts you in the broker market or the PE market — or close enough to the threshold that 12 months of preparation could move you across it.
