You ran the numbers. You know your EBITDA, you have a rough sense of what your business is worth, and you've decided you want to sell. Now what? For most HVAC owners, this is where the process stalls. There's a real gap between “I want to sell” and “I have a signed LOI,” and most owners try to navigate it alone or with the first advisor who returns their call.
That's almost always a mistake. The single biggest driver of exit value — beyond your EBITDA, beyond your multiple, beyond your recurring revenue mix — is whether you run a competitive process with professional representation or negotiate with one buyer at a time. Unrepresented sellers leave money on the table. The research is clear on this, and experienced PE buyers know it.
This post explains exactly who you need to hire, what they actually do, what it costs, and how to evaluate whether someone is worth bringing onto your deal. If you're at the “I know my number — now what?” stage, this is the guide you need.
M&A Advisor vs. Business Broker: What's the Difference?
These terms get used interchangeably, but they describe fundamentally different services — and the distinction matters enormously for an HVAC business targeting PE buyers.
Business brokers are generalists. Their model is built around listing businesses on platforms like BizBuySell, fielding inbound inquiries from individual buyers, and closing Main Street transactions — the dental practice, the dry cleaner, the small restaurant. They typically charge 10–12% on deals under $2M. They're adequate for businesses with enterprise values under $2M selling to individual owner-operators. They are not equipped for PE-backed processes.
M&A advisors are specialists. Their model is built around running structured sell-side processes for middle-market businesses — typically $2M–$25M in enterprise value. They work with multiple PE firms, strategic acquirers, and financial buyers simultaneously. They charge lower percentages (3–6% success fee) on larger deals, and they bring something a broker cannot: competitive tension between multiple serious buyers that drives your final price toward the top of the range rather than the middle of it.
Brokers find one buyer:
Their process is sequential: list, market, field inquiries, negotiate with one party. Each negotiation is a price negotiation with no competitive floor.
Advisors run a process:
They approach 20–40 buyers simultaneously, collect competing Indications of Interest, and use real pricing tension to push your multiple to the upper end of the range — sometimes dramatically.
For an HVAC business with $500K–$5M in EBITDA targeting PE buyers, an M&A advisor who knows the home services vertical is almost always the right call. The home services PE market is active and competitive — there are enough well-capitalized buyers that a properly run process will produce multiple offers. A broker listing you on BizBuySell will not reach those buyers.

Hiring an advisor isn't handing off the deal and waiting for a wire. It's bringing on a team that runs a parallel process to your business operations for 6–12 months. Here's what that process looks like:
Prepare the CIM
The Confidential Information Memorandum is the pitch book for your business — typically 20–40 pages covering your history, financials, operations, management team, market position, and growth thesis. A good CIM pre-answers the questions buyers will ask in due diligence and frames your business in the context serious PE firms use to underwrite deals. A bad CIM leaves buyers with unanswered questions, which they fill in with conservative assumptions.
Identify and approach 20–40 buyers
Your advisor maintains a proprietary database of PE firms, family offices, and strategic acquirers actively pursuing home services acquisitions. They know who has dry powder, who just closed a platform deal and is looking for add-ons, and who pays the highest multiples for HVAC businesses at your scale. This institutional knowledge is not replicable by a general broker or an owner going direct.
Manage NDAs and the IOI stage
Qualified buyers sign confidentiality agreements, receive the CIM, and return Indications of Interest — non-binding price signals that tell you who is serious and at what valuation. Your advisor uses the IOI stack to identify your best 3–5 buyers and structure a competitive process around them.
Run management presentations
Shortlisted buyers get a 2–3 hour session with you and your management team. Your advisor prepares you for every question, coaches your delivery on sensitive topics (owner dependency, customer concentration, deferred capex), and controls the information flow to maintain competitive tension across multiple buyer conversations happening in parallel.
Negotiate LOIs
After management presentations, buyers submit Letters of Intent. Your advisor analyzes each LOI for price, structure (cash vs. earnout vs. rollover equity), exclusivity period, and hidden terms that could reset your price during due diligence. They negotiate LOI terms aggressively — this is where advisors earn their fee, because most owners don't know what's negotiable and what isn't.
Manage due diligence through closing
After signing the LOI, your advisor coordinates with your deal attorney and the buyer's team through Quality of Earnings, legal due diligence, and final documentation. They track open items, protect you from scope creep in the diligence process, and bridge communication breakdowns that derail deals at the finish line.
What It Costs
M&A advisor fees have two components: a retainer and a success fee.
Retainer: Most advisors charge $5K–$20K upfront, credited against the success fee at close. This covers CIM preparation, initial buyer outreach, and the first few months of process management. Think of it as skin-in-the-game money — it filters out sellers who aren't serious and compensates the advisor for real work if the deal doesn't close.
Success fee: Structured on a modified Lehman formula — typically 5% on the first $5M of enterprise value, 3–4% on the next $5M. Exact structures vary by firm and deal size; some advisors use a flat percentage, others use a tiered scale. The important thing is that the fee is performance-linked: if the deal doesn't close, you pay only the retainer.
Fee Example: $4M Exit
On a $4M exit, expect to pay roughly $150K–$220K in total advisor fees. That sounds like a lot until you run the other side of the math: a well-run competitive process typically adds $500K–$1M to your exit price versus an unrepresented or single-buyer negotiation. The fee is real. So is the value.
5 Questions to Ask Before Hiring an HVAC M&A Advisor
Not every advisor who claims to know HVAC actually knows PE-backed home services transactions. These five questions will tell you quickly whether you're talking to someone who can deliver.
Question 1: "Have you closed HVAC or home services deals in the last 24 months?"
Industry experience matters more than general M&A experience when selling to PE. PE buyers who specialize in home services use HVAC-specific metrics (recurring revenue mix, tech-to-revenue ratio, maintenance agreement penetration) to underwrite deals. An advisor who has never worked in this vertical will not know how to frame your business or which buyers to approach first.
Question 2: "How many active deals are you running right now?"
More than 8–10 active engagements is a red flag. Sell-side processes require consistent attention — buyer follow-up, diligence management, negotiation coordination. An advisor stretched across too many deals will not give yours the focus it needs. You want someone who can be on the phone with a buyer the same day a question comes up.
Question 3: "How many buyers will you approach, and how do you build that list?"
Fewer than 15 qualified buyers is a red flag. A credible advisor has a proprietary database of PE firms actively acquiring in home services, not just a list of names from Google. Ask them to walk you through their process: how do they qualify buyers, how do they tier outreach, and how do they maintain competitive tension across simultaneous conversations?
Question 4: "What is your success rate and average time-to-close?"
Industry standard for a signed LOI is 6–12 months from engagement. Total close (LOI through funding) typically runs 3–5 months after that. Ask what percentage of their engagements result in a closed deal, and what causes the ones that don't close to fall apart. If they can't answer this clearly, they haven't run enough processes to have reliable data — which tells you something.
Question 5: "Can I speak to 2–3 business owners you have represented?"
References are non-negotiable. Any advisor worth hiring has past clients willing to speak on their behalf. Ask references specifically: Did the advisor set realistic expectations on valuation? Were they responsive during the process? Did the final price meet or exceed expectations? Would you hire them again?
Where to Find HVAC-Focused M&A Advisors
The right advisor is rarely the one who finds you first. Here's where to look:
Mid-market investment banks with home services practices:
Several regional and national investment banks have built dedicated home services practices specifically because PE activity in HVAC, plumbing, and electrical has been so strong over the last decade. These firms know the buyers, understand the metrics, and have closed dozens of comparable transactions. Ask your CPA or business attorney for names.
Regional M&A advisory firms specializing in trades:
Smaller boutique advisory firms often have deeper relationships with PE firms in the $10M–$50M enterprise value range than larger banks, because they focus exclusively on this segment. They may carry fewer deals simultaneously, which translates to more attention on yours.
Referrals from your CPA, attorney, or other HVAC sellers:
The most reliable source. A CPA who has worked with HVAC owners through previous transactions has seen which advisors actually deliver and which ones overpromise. Other HVAC owners who have sold to PE are the best possible reference pool — they have lived the process.
HVAC industry associations:
ACCA and PHCC both maintain networks of advisors and service providers who specialize in the trades. Industry conferences are a reasonable place to build a shortlist of names to evaluate.
Start with Your Number
Before you call any advisor, know your number. The first question every competent M&A advisor will ask in an initial conversation is: “What do you think the business is worth, and what are your assumptions?”
Owners who can answer that question clearly — with a documented EBITDA figure, a list of defensible add-backs, and a realistic multiple range based on comparable transactions — come across as serious sellers. Owners who say “I'm not sure, that's kind of why I'm calling” signal that the deal will be difficult. Advisors have discretion over which engagements they take. A prepared seller with a coherent story gets better advisors on better terms.
Coming in with a clear EBITDA figure, your PE Readiness Score, and a defensible valuation range puts you ahead of 90% of sellers. Most HVAC owners who call an advisor for the first time have never run their own numbers — they're relying on the advisor to tell them what the business is worth, which immediately hands pricing leverage to someone whose interests are not perfectly aligned with yours.
Know your number first. Then call the advisor.
