If you own an HVAC, plumbing, or electrical company and you’ve thought about selling — even casually — the first question is always the same: what’s my business worth?
The short answer is that your business is worth whatever a buyer will pay for it. But that’s not helpful. What’s actually helpful is understanding how buyers think about value, which numbers they focus on, and — most importantly — the counterintuitive dynamics that can mean a higher-margin company gets a lower valuation than a competitor with thinner margins.
I spent years on the buy side of home services M&A — reviewing over 200 acquisitions on the buy side, including at Apex Service Partners. Every deal had its own story, but the valuation framework was remarkably consistent. Here’s how it works.
How Home Services Companies Are Valued
Most home services company acquisitions are priced as a multiple of EBITDA — Earnings Before Interest, Taxes, Depreciation, and Amortization. EBITDA is the buyer’s proxy for the cash flow the business generates from its operations, independent of how it’s financed or taxed.
The formula is straightforward:
Enterprise Value = EBITDA × Multiple
If your company generates $1.2M in adjusted EBITDA and the buyer applies a 5× multiple, the enterprise value is $6M. The actual purchase price may differ after adjustments for working capital, debt, and other items, but the multiple × EBITDA framework is the starting point for virtually every home services deal.
The two variables that matter are the EBITDA dollars and the multiple. Both are within your influence.
What Determines the Multiple
Here’s what typical EBITDA multiples look like by company size, assuming roughly 20% EBITDA margins:
| Revenue | ~EBITDA (at ~20%) | Typical Multiple | Implied Enterprise Value |
|---|---|---|---|
| Under $5M | ~$1M | 5–6× | $5M–$6M |
| $5M–$15M | $1M–$3M | 6–8× | $6M–$24M |
| $15M+ | $3M+ | 10×+ | $30M+ |
The range reflects real differences in quality, scale, and risk. Here’s what drives where a company lands.
Revenue Scale
This is the single biggest factor. Larger companies trade at higher multiples, period. A $10M revenue company with $1M of EBITDA will trade for meaningfully more than a $4.5M company with the same $1M of EBITDA — even though the smaller company has better margins.
The reason is simple: larger companies give the buyer a bigger platform to build on. They have more customers, more trucks, more market coverage, and more infrastructure to absorb bolt-on acquisitions. All of that is worth a premium.
Revenue Mix
Not all revenue is created equal. Buyers pay more for revenue that is recurring, high-margin, and not dependent on bidding or construction cycles.
Service and repair revenue commands the highest premium. It’s recurring (customers have problems every year), high-margin, and relatively predictable. Maintenance agreements are even more valuable — they lock in multiple touchpoints per year and create the foundation for upselling repair and replacement work.
Replacement/install revenue is valued normally — it’s project-based but high-margin and driven by the installed base.
New construction revenue is discounted significantly. It’s cyclical, low-margin, bid-dependent, and creates concentration risk with builders. A company doing 40%+ of revenue in new construction will see its multiple compressed by 1–2 turns relative to a comparable company doing 80%+ in service and replacement.
Management Team
A company that can operate profitably without the owner in the field every day is worth significantly more than one where the owner is the top technician, the head salesperson, and the primary customer relationship. Buyers are buying a business, not a job — and owner-dependent companies carry integration risk that gets priced into the multiple.
If you’re the one answering every customer call, running every estimate, and managing every callback, a buyer sees key-person risk. Building a management layer — an operations manager, a service manager, a lead installer — is one of the highest-ROI investments you can make for valuation purposes.
Customer Concentration
If your top 5 customers represent more than 20–25% of revenue, that’s concentration risk. In residential service, this is rarely an issue (you have thousands of individual customers). But companies with significant commercial or builder accounts can have this problem. Buyers will either discount the multiple or structure an earnout around retaining those key accounts.
Market and Geography
Companies in growing Sun Belt markets (Texas, Florida, Arizona, the Carolinas) tend to command slightly higher multiples than those in flat or declining markets. This reflects the buyer’s confidence in future revenue growth — a company in a growing MSA has more organic upside than one in a stagnant market, even if the current financials are similar.

Why? Because when a PE firm acquires a company, one of their primary value creation levers is margin improvement. If they buy a company doing 12% EBITDA margins and improve it to 18% through operational changes, they’ve created significant value. That margin improvement potential is baked into the offer.
But if a company is already running at 22% EBITDA margins, there’s less room for the buyer to improve. One of their value creation levers is capped. That doesn’t mean the business is worth less in absolute terms — the EBITDA dollars are still higher. But the multiple applied to those dollars may be lower because the upside is more limited.
The practical takeaway: if your margins are below 15%, margin improvement is your top priority because it directly increases both the dollars and the multiple. Once you’re above 18–20%, the highest-value move shifts to revenue growth — expanding your service area, adding a trade, acquiring a smaller competitor, or investing in marketing to grow the topline.
Adjusted EBITDA: What Gets Added Back
Buyers don’t just look at the EBITDA number on your tax return or financial statements. They restate — or “adjust” — your EBITDA to reflect what the business would earn under normalized ownership. Common add-backs include:
Owner compensation above market. If you’re paying yourself $400K but a GM could run the business for $175K, the $225K difference gets added back to EBITDA. This is often the single largest adjustment.
Owner perks. Personal vehicles, club memberships, travel, meals, and other personal expenses run through the business. These get added back.
One-time expenses. A lawsuit settlement, a roof repair, a one-time consulting project — anything that’s non-recurring gets added back.
Related-party transactions above market. If you’re leasing the building from yourself at above-market rent, or paying a family member above-market salary for their role, the excess gets normalized.
Depreciation and amortization. These are non-cash charges and part of the EBITDA definition, so they’re always added back.
The add-back process is standard and expected. But be realistic — aggressive add-backs that a buyer can’t verify will get challenged. Every dollar you add back to EBITDA needs a clear rationale and documentation. Buyers who feel like the seller is inflating EBITDA with questionable adjustments lose trust, and that’s worse for the deal than a slightly lower EBITDA number.
What You Can Do Now to Maximize Value
Even if a sale is 3–5 years away, the things that drive valuation take time to build. Here are the highest-impact moves.
Clean Up Your Financials
Separate your P&L by department (service, install, new construction). Move owner compensation to overhead. Eliminate personal expenses from the business. Make sure your financials tell the story of a well-run company. A buyer who opens your P&L and sees clean, organized financials immediately has more confidence in the business. One who sees a mess starts looking for problems.
Build a Management Team
Hire or develop at least one layer of management between you and the front-line technicians. An operations manager, a service manager, a sales manager — the specific roles depend on your size, but the principle is the same. The business needs to function without you in the field.
Strengthen Your Service vs. Install Mix
Every maintenance agreement customer is worth more than a one-time service call customer. You touch them multiple times per year, they’re more likely to accept repair and replacement recommendations, and each visit creates another sales opportunity that buyers value at a premium. If you don’t have a maintenance plan program, start one. If you do, invest in growing it.
Shift Your Revenue Mix Toward Service
If new construction or low-margin project work is dragging down your blended margins and creating builder dependency, develop a plan to shift the mix. Invest in marketing that drives residential inbound calls. Build a service brand. The transition takes time, but the valuation impact is significant.
Document Everything
Standard operating procedures, org charts, vendor contracts, customer lists, fleet schedules, marketing ROI by channel — all of it. A well-documented business is easier to evaluate, easier to integrate, and signals to a buyer that the operation is transferable. Undocumented businesses carry integration risk, and risk compresses multiples.
Maintain Consistent Growth
A company with 10% year-over-year revenue growth for three consecutive years is worth meaningfully more than one with flat or volatile revenue, even if the current-year EBITDA is the same. Growth trajectory gives buyers confidence in future performance, and that confidence translates to a higher multiple.
The Timeline Question
Most HVAC, plumbing, and electrical company owners who eventually sell wish they’d started preparing earlier. The financial cleanup, management team development, revenue mix optimization, and documentation work all take 1–3 years to fully implement and show up in the numbers.
If you’re thinking about a sale in the next 2–3 years, the time to start is now. The decisions you make about pricing, hiring, marketing mix, and financial management today will directly determine what a buyer is willing to pay when you’re ready.
And if a sale is 5+ years away or not on your radar at all — every single thing that makes your company more valuable to a buyer also makes it more profitable and easier to run today. There’s no downside to operating like a company someone would want to buy.
