The call came in on a Tuesday afternoon. Someone from a PE-backed roll-up — maybe Apex, maybe a firm you've never heard of — asking if you'd consider a conversation about your business. You told them you'd think about it. Now you're on Google at 10 PM wondering: do I need a broker, or can I just talk to them directly?
It's the right question. And the tension is real: business brokers and M&A advisors charge 3%–5% of transaction value. On a $10M deal, that's $300K–$500K walking out the door before you cash the check. But the data on unrepresented sellers in PE transactions is equally unambiguous — they almost always leave more than that on the table.
This post gives you the math, the decision framework, and a third path most HVAC owners never consider. But before any of it: the most important thing you can do right now — before talking to a broker, an M&A advisor, or the PE firm — is know what your business is actually worth.
What a Broker (M&A Advisor) Actually Does
“Broker” and “M&A advisor” get used interchangeably, but they describe very different services. For a middle-market HVAC business targeting PE buyers, the distinction matters. A generalist business broker lists your company on BizBuySell and waits for inbound inquiries. An M&A advisor runs a structured sell-side process — simultaneously approaching 20–40 qualified buyers to create the competitive tension that drives your multiple to the top of the range.
Here's what a proper M&A process actually delivers:
Controlled auction — the most valuable thing a broker does
A competitive process means multiple PE firms are simultaneously interested and aware of each other's interest. When a buyer knows there are three other bidders, they submit their best number — not their opening number. Without competition, there is no market price. You accept whatever the PE firm offers or you walk away. That's not a negotiation; it's a take-it-or-leave-it.
Prepares the CIM (Confidential Information Memorandum)
The CIM is the formal sell-side document PE firms use to underwrite your deal — 20–40 pages covering your financials, EBITDA bridge, customer breakdown, operations, management team, and growth story. A well-prepared CIM pre-answers due diligence questions and frames your business the way serious PE firms think about acquisitions. A poorly prepared CIM (or no CIM) leaves buyers filling in gaps with conservative assumptions that show up as downward price adjustments.
Manages the data room and QoE process
Your advisor coordinates the virtual data room, manages information requests from multiple buyers simultaneously, and bridges communication between your team and the buyer's deal team during Quality of Earnings. Their job is to protect you from scope creep — requests designed to extend the diligence window and find retrade leverage.
Negotiates LOI terms and purchase price adjustments
The Letter of Intent is not just a price — it's a structure. Working capital targets, earnout mechanics, rollover equity percentages, representations and warranties, and indemnification caps are all negotiated at the LOI stage. Advisors know what's standard, what's negotiable, and what's a red flag. Most unrepresented sellers don't.
Protects against retrades
Retrades — where a buyer drops their price after the LOI based on diligence findings — are common in PE transactions. An experienced advisor's relationship with buyers creates accountability. PE firms know advisors have long memories and future deal flow. A buyer who retrades without justification pays a reputational price. An unrepresented seller has no such protection.
Best for: businesses with $2M+ EBITDA going through a full competitive process (12–18 months from engagement to close). For the full breakdown of what M&A advisors charge and 5 questions to ask before hiring one, see the companion guide on finding the right M&A advisor for your HVAC business.

Calculate My Valuation →What “Selling Direct to PE” Actually Means
“Direct to PE” usually means one thing: you responded to unsolicited inbound from a PE consolidator and started talking to them without professional representation. This is not a negotiation strategy. It's the absence of one.
Here's what you're walking into:
The PE firm's deal team is there to buy at the lowest defensible price:
They are not there to pay you what the business is worth. They are there to pay the least they can while keeping the deal from falling apart. Their analysts have modeled your financials. Their deal team has done dozens of these transactions. If you're unrepresented, you are the least experienced person in every conversation.
Without competition, there's no market price:
A market price requires multiple buyers competing. One buyer giving you a number is not a market price — it's an opening offer from someone whose job is to buy businesses cheaply. The only way to know if their number is fair is to know your own number independently, and ideally to have 2–3 other buyers' numbers to compare it against.
The 0.3x–0.8x unrepresented seller discount is real:
Industry data from GF Data shows unrepresented sellers in PE roll-up transactions consistently receive 0.3x–0.8x less on their EBITDA multiple compared to represented sellers completing comparable transactions in the same market. That gap is not because their businesses are worth less. It's because they had no competitive process and no professional to catch what they were leaving behind.
When it can work: sub-$1M EBITDA with a good attorney:
For businesses with EBITDA below $500K, the math can flip. Broker fees of 4%–5% on a $2M–$3M transaction can absorb 20%+ of the proceeds, exceeding the value of representation. In these cases, a direct deal with experienced legal counsel negotiating on the structural terms (and the seller running the calculator first to anchor the price) is a defensible path.
The Math: Does the Broker Fee Pay for Itself?
Let's run the numbers on a real business. $1.5M EBITDA. Two scenarios.
Base Business
$1.5M EBITDA · $8M+ revenue · Solid recurring revenue mix · Competitive market
- M&A advisor runs controlled auction with 4 competing buyers
- Multiple buyers drive final price to 5.25x EBITDA
- Gross exit: $7.875M
- Broker fee at 4%: $315K
Net proceeds
$7.56M
After 4% broker fee
- Responds to unsolicited inbound from PE consolidator
- Single buyer, no competition, accepts their number
- Multiple at 4.5x EBITDA (0.75x below market)
- No advisor fee
Net proceeds
$6.75M
No fee, but no competition
Net advantage of representation: ~$810K
The broker paid for itself three times over. The $315K fee produced $1.125M in additional gross proceeds — a 3.6x return on representation cost before the first negotiation even started.
The Hybrid Path Most HVAC Owners Miss
There's a third option that sits between “ignore the PE call” and “immediately hire an M&A advisor for a full 12-month process.” Most HVAC owners never consider it.
Run the calculator first — before any conversation
Before you respond to the PE firm's email or pick up the phone, know your number. The OffRamp calculator gives you an estimated valuation range and PE Readiness Score in 3 minutes. That number is your anchor. When the PE firm quotes you 4.2x and your calculator says 5.0x–5.5x is the right range for a business with your profile, you know exactly where you stand — and you know not to accept their opening offer.
Take 2–3 inbound calls, collect soft LOIs
You can take exploratory calls with PE firms without committing to anything. Ask each one for a preliminary indication of value — non-binding and confidential. Most will provide a range. Now you have market data: real buyers, real numbers, in the current market. This data is extraordinarily valuable.
Hire a broker to run a competitive process with those buyers as anchors
When you bring an advisor into a process where you already have 2–3 interested buyers with preliminary numbers, their job is easier — and your position is stronger. They know there's real demand. Buyers know they're in a competitive situation. The advisor can run a compressed process (often 6–9 months instead of 12–18) and use the existing interest to drive competitive tension rather than cold-starting from scratch.
The result: speed, competition, and market-tested demand
You've done the free prep work (the calculator, the inbound calls), you've validated market demand, and you've brought in professional representation to maximize the outcome. The hybrid path uses the PE firm's inbound interest as an asset rather than accepting their framing that this is a bilateral negotiation.

The Decision Matrix: Which Path Is Right for Your Business?
The broker-vs.-direct question has a clean answer once you know your EBITDA. Here's the framework:
- Enterprise value typically $1M–$3M — broker fee at 4%–5% absorbs $40K–$150K, which can exceed the value of competitive tension at this scale
- Focus on finding a business attorney with M&A experience, not a generalist broker
- Run the calculator first so you have an independent price anchor before any buyer conversation
- Know the PE Readiness factors — even without a broker, showing up informed changes the negotiation
- This is the core range where competitive tension adds the most relative to fee cost
- The 0.5x multiple differential ($375K–$1M in gross proceeds for a $750K–$2M EBITDA business) easily clears a 4% advisor fee
- Consider the hybrid path: take 2–3 inbound calls, collect soft LOIs, then bring in an advisor to formalize a competitive process
- At minimum, know your number before talking to any buyer
- At this scale, a formal process with 20–40 buyer outreach, CIM preparation, and managed auction is standard
- PE firms expect it — an unrepresented seller at this deal size signals inexperience, which they factor into their opening offer
- The competitive process premium at $2M+ EBITDA routinely exceeds $1M–$3M, making the 3%–5% fee one of the highest-ROI decisions you'll make
- Engage an advisor 12–18 months before your target close date to have time to optimize and prepare
- Run the calculator before you respond to any PE outreach — takes 3 minutes and gives you the anchor you need
- Ask for their preliminary indication of value before disclosing detailed financials
- Don't sign an exclusivity agreement before you've talked to at least 2–3 other buyers
- The PE firm called you because they want to buy your business. That means it's worth buying — from someone. The question is whether they're the right buyer at the right price.

Platform-eligible businesses (scoring 66+ on the PE Readiness Score) should always run a full process — here's why.
The One Thing That Changes the Math on Every Path
Whether you go broker, direct, or hybrid — the single factor that changes your outcome on every path is whether you know your PE Readiness Score before you start.
Your PE Readiness Score is a factor-by-factor assessment of the five things PE buyers evaluate before deciding what multiple to pay: your recurring revenue mix, your owner-independence, your financial documentation quality, your software systems, and your revenue growth trajectory. A seller who walks into any process knowing these numbers — and knowing which ones are dragging their multiple — has leverage regardless of whether they're represented.
A seller who doesn't is negotiating blind.
PE Readiness Score — What It Measures
Recurring Revenue
Documented maintenance agreement renewal rates, contract value, and penetration rate
Owner-Independence
How much of the business runs without you — service management, sales, operations
Clean Financials
GAAP-compliant normalized EBITDA with documented add-backs
Software Systems
24+ months of clean FSM data (ServiceTitan, FieldEdge) with performance metrics
Growth Trajectory
3-year revenue CAGR with documented growth story (market expansion, share capture, service mix)
The combined impact of all five factors is a 4x–5x difference in outcomes on the same underlying EBITDA. For a detailed breakdown of each factor and its dollar impact, the valuation calculator vs. CIM guide explains exactly when each tool is appropriate and what each one measures. For the management team factor specifically — which is worth 20 points in the PE Readiness Score and the second-highest-weighted factor — see the guide on how to structure your HVAC management team before selling to PE.
The Broker Question Is the Wrong First Question
Most HVAC owners frame this as a binary choice: hire a broker and pay a fee, or go direct and save it. Neither framing is right, because both start in the middle of the process.
The right sequence is: run the calculator → know your number and your PE Readiness Score → make an informed decision about representation → engage a process. An owner who does that first step is better positioned in every downstream scenario — with a broker, without one, or somewhere in between.
The PE firm that called you on Tuesday knows exactly what your business is worth. The only question is whether you do.
