Key Takeaways
- A heating, ventilation, and air conditioning (HVAC) or plumbing business making $500,000 a year can sell for $150,000 to $600,000 or more, based on the profit a buyer keeps.
- Buyers value these companies on earnings using income, market, and asset methods, with asset value (equipment and receivables minus liabilities) usually setting the price floor.
- Seller’s Discretionary Earnings (SDE) values owner-operated businesses, while crew-run companies trade on Earnings Before Interest, Taxes, Depreciation, and Amortization (EBITDA), both usually at 2x to 4x.
- At a 3x multiple, $95,000 in SDE points to about $285,000, while $150,000 in SDE points to $450,000, or $600,000 at 4x with recurring revenue and low owner dependency.
- Core Growth Group was founded by Clint, an operator who runs his own service business, and helps owners grow earnings now so the business commands a stronger multiple when it’s time to sell.
Why Earnings, Not Revenue, Set the Price
An HVAC or plumbing company bringing in $500,000 a year can be worth somewhere between $150,000 and $600,000, and the profit underneath those sales decides where it lands. Buyers pay for the cash flow left after expenses and for how confident they are that it will keep coming in. If you assume your business is worth something close to its revenue, you’re making the most common mistake owners make.
That assumption shapes everything that follows. If you anchor to revenue, you may reject realistic offers, and if you skip preparation, you hand buyers reasons to discount your earnings. Core Growth Group was founded by Clint, an operator who bought and runs his own service business, and he looks at every company through owner earnings, the same lens used in the examples below.

How Business Valuation Actually Works
Every credible valuation method boils down to answering one question: how much reliable profit does this business generate, and how confident can a buyer be that it keeps generating it? The question is the same for a $500,000 shop and for a business making $1 million a year. It depends on the size and type of business.
Revenue is the total amount of money a business brings in before any expenses are subtracted. Profit, specifically the earnings a buyer can expect to walk away with, only shows up after payroll, rent, supplies, marketing, and every other operating cost gets paid.
A $500,000-revenue HVAC company spending heavily on subcontracted labor and equipment leasing might net $80,000 in owner earnings, while a leaner competitor with the same revenue nets $150,000. Those two businesses are not worth the same amount, even though their top-line numbers match exactly.

Four Business Valuation Methods
Income Approach: Seller’s Discretionary Earnings (SDE)
SDE is the standard metric for smaller, owner-operated businesses. Start with net income on the P&L, then add back expenses that would not carry over to a new owner:
- The owner’s salary and personal draw
- Interest, depreciation, and amortization
- Personal expenses run through the business, such as a vehicle or travel costs
- One-time or non-recurring costs, like a single large equipment repair
The result is typically multiplied by 2x–4x. A business with $150,000 in SDE at a 3x multiple would be valued around $450,000.
Income Approach: EBITDA Multiples
Earnings before interest, taxes, depreciation, and amortization (EBITDA) is the standard for businesses run by crews and managers rather than one hands-on owner.
As a company grows past the owner-operated stage, buyers move from SDE to EBITDA. From a strategic buyer’s perspective, a baseline HVAC or plumbing company around $5 million in revenue often lands near 3x, while consistent growth of 20% to 30% or more per year can support a multiple closer to 4x.
Market-Based Comparisons
This method looks at what similar businesses recently sold for, then adjusts for differences in size, location, growth, and margins. The strongest prices tend to go to businesses with steady cash flow, a diverse customer base, and clean financial records.
Asset-Based Valuation
This approach adds up the market value of everything the business owns, then subtracts its liabilities. A plumbing company with $175,000 in trucks, equipment, inventory, and receivables and $40,000 in liabilities would be valued at $135,000, regardless of its profit.
Asset value leaves out customer relationships, reputation, and growth potential, so it usually understates a profitable company. Most owners treat it as a floor, and real-world deals usually blend earnings and market methods to reach a final number.
How Much Is a $500,000 Revenue Business Worth?
A business with $500,000 in revenue could sell for anywhere from about $150,000 to $600,000 or more. Revenue alone can’t answer the question. What a buyer pays for is the profit sitting underneath that revenue line, and two companies at $500,000 can hand over very different amounts of it.
That profit is measured as SDE and multiplied by 2x–4x, depending on how stable the earnings look to a buyer.

Low-Profit Example: About $150,000
A business running on thin margins might produce only $75,000 in SDE. At a 2x multiple, which reflects high owner dependency or unpredictable revenue, the illustrative value is around $150,000, less than a third of revenue.
The multiple sits at the low end when the owner handles most client relationships personally, keeps inconsistent records, or depends on one or two large customers.
Moderate-Profit Example: About $285,000
At $95,000 in SDE and a 3x multiple, the illustrative value sits near $285,000. Businesses in this band usually have better margins, steadier bookkeeping, and customers who came from somewhere other than the owner’s phone contacts.
Stronger-Margin Example: About $375,000
At $125,000 in SDE and the same 3x multiple, the illustrative value rises to $375,000. Because the multiple stays at 3x, the full $90,000 gain over the moderate scenario comes from higher profit. That shows how much margin matters compared to revenue growth.
Businesses at this level often have repeat customers, documented pricing, and fewer personal expenses running through the books.
High-Profit Example: $450,000–$600,000
At $150,000 in SDE, a 3x multiple puts the value at $450,000. A 4x multiple, which reflects recurring revenue, documented systems, and low owner dependency, pushes the same earnings to $600,000.
Two owners in the same revenue bracket can walk away with very different outcomes. If you document your processes, spread revenue across more customers, and tighten your financial reporting, you’re the one positioned for the higher multiple on the same profit.
Grow Your Earnings Before You Set a Price With Core Growth Group

The value of a $500,000 HVAC or plumbing company comes down to the gap between reported and real profit: documented earnings, dependable customers, and operations that keep running when the owner steps away. Getting that number wrong can scare off serious buyers or leave earned money on the table.
Core Growth Group acquires HVAC and plumbing service businesses across the Texas Triangle, and we evaluate each company on its owner earnings rather than top-line revenue alone. If you’re weighing a sale, talk with Core Growth Group about where your business realistically lands.
Frequently Asked Questions (FAQs)
Is SDE or EBITDA used to value an HVAC business?
It depends on how the business runs. SDE fits smaller, owner-operated companies because it adds back the owner’s salary and personal expenses.
Once crews and managers run daily operations rather than one hands-on owner, buyers switch to EBITDA and typically apply a 2x–4x multiple.
How long does it take to sell a small business?
Selling a service business usually takes many months, often 12 months or more from preparation to close. Preparation alone, including cleaning up financials, documenting systems, and stress testing the business, typically takes around 12 months.
Businesses with clean records, documented systems, and diversified customers generally move faster through due diligence than those that need extensive cleanup before a buyer can confidently make an offer.
What is a good profit margin for a service business?
Margins vary widely by trade, overhead structure, and labor model. In the examples above, SDE margins range from 15% ($75,000) to 30% ($150,000) on $500,000 in revenue, and the higher-margin businesses reach much higher values. Beyond the percentage, buyers look for consistency.
A service business reporting stable margins year over year, even moderate ones, typically earns a stronger multiple than one with higher but unpredictable margins. Clean financial reporting that shows revenue, costs, and profitability trends matters as much as the margin itself.
Can I increase my business value before selling?
Yes. This is the Prepare stage of Core Growth Group’s Grow, Prepare, Exit framework, and it usually starts about 12 months before a sale. Reducing owner dependency through documented SOPs, improving customer retention and diversification, and cleaning up financial reporting are among the most effective ways to raise the multiple a buyer will pay on the same dollar of profit.
AI tools help here too: automated booking, customer follow-up, AI phone assistants, and review requests keep work flowing without the owner handling every call.
How is selling to Core Growth Group different from listing with a broker?
A broker lists your business and markets it to outside buyers, a process that can take many months with no guarantee of a sale. Core Growth Group is a direct strategic buyer led by Clint, an operator who runs his own service business and buys HVAC and plumbing companies himself.
Qualified owners can talk directly with the buyer instead of going through a public listing, and owners who aren’t ready yet can work with Core Growth Group to grow and prepare first.
