HVAC Business Valuation: What Your Company Is Worth and Why

An HVAC business valuation comes down to one multiplication: what the owner earns in a year, times a multiple. For a company under about $5 million in revenue, the published multiples run from 2 to 5 times seller's discretionary earnings, and most bands center near 3.

This guide is for the owner of a residential or light commercial HVAC company who is three months to five years from a sale. It is education, not an appraisal. Nothing here is tax or legal advice, so get a professional valuation before you sell. Every figure here was read on November 14, 2026.

HVAC business valuation starts with what the owner earns

Buyers do not pay for revenue. They pay for the cash the company hands its owner each year, and then they multiply it. Viking Mergers and Acquisitions makes the point with an example: a $10 million company on thin margins can be worth less than a $6 million company with strong ones.

For a small company, the earnings measure is seller's discretionary earnings, or SDE. It is net profit plus everything the business pays for the owner's benefit, plus costs a new owner would not carry. Each addition is called an add-back.

How to value an HVAC business in four steps

1. Start with net profit. Use last year's tax return or the accountant's profit and loss statement, not a number from memory.
2. Add back the owner. Salary, the payroll taxes on it, the owner's truck, health insurance and any family phone plan the company pays.
3. Add back what will not repeat. Interest, depreciation, amortization and one-time costs such as a legal bill. Keep the invoice for each.
4. Multiply. Apply a multiple from the tables below, then run the same math on the two years before to show the trend.

Here is the schedule for an example company. The figures are an illustration, built to match the default in the calculator further down.

The example company bills $1.5 million a year, so SDE is 16% of revenue. At a multiple of 3, the math gives $720,000.

Add-backs are where sellers and buyers argue. Clearly Acquired's guide says they can shift earnings by 15% to 40%, and Raincatcher says buyers trace each one to an invoice. Its summary of the whole process is six words long: "Buyers price what they can verify."

SDE or EBITDA: the size of the deal picks the measure

EBITDA is earnings before interest, taxes, depreciation and amortization. Unlike SDE, it treats a manager's salary as a cost, because the buyer does not plan to run the trucks personally. For the same company, EBITDA is the smaller number and its multiple is the larger one.

That is why a 5x offer on EBITDA and a 3x offer on SDE can be the same price. Compare multiples only when both sit on the same earnings measure.

The sources draw the line in different places and agree on the direction. Home Services Business Valuation prints an SDE band alone for companies up to $1.5 million in revenue and both measures from $2 million up. The calculator in this guide uses SDE, the measure that fits a company under about $5 million in revenue.

What the published HVAC business multiples say, source by source

No public database prints HVAC sale prices with a sample you can audit. What exists is a set of bands from brokers, valuation firms and software vendors, plus one trade survey that covers every industry. Here is each SDE band with its date.

We put the seven bands side by side and took the midpoint of each. The midpoints run from 2.75x to 3.75x, and the median is 3.0x. None of the seven prints how many HVAC sales sit behind its band.

One outlier is left out. FieldCamp's guide also carries a table with 4.8x to 7.9x for companies earning $500,000 or more of SDE. No other publisher prints SDE multiples that high, and the figures sit closer to its own EBITDA tables.

The one figure with a stated sample is the Market Pulse survey from the International Business Brokers Association (IBBA) and M&A Source. Its second-quarter 2026 edition drew 255 brokers and advisors, who reported 181 closed deals. It covers every industry, so read it as the backdrop for the HVAC bands.

Two things stand out. The HVAC midpoints land almost exactly on the survey's multiples for deals between $500,000 and $2 million, which is a point in favor of the bands.

Size alone moves the multiple too. A dollar of earnings in the largest SDE band sold for 3.1x against 2.0x in the smallest, which is 55% more for the same dollar.

What is my HVAC business worth? Run your own numbers

Set your revenue, your SDE as a share of revenue and a multiple inside the published band in the calculator below. The switches apply the adjustments covered in the next section, each at the low end of its printed range.

What an HVAC business might sell for

Default input or result	Figure
Annual revenue	$1,500,000
SDE at 16% of revenue	$240,000
Low end of the band, 2.0x SDE	$480,000
Estimate at 3.0x SDE	$720,000
High end of the band, 5.0x SDE	$1,200,000

What moves the multiple	Turns	Printed by
Service agreements are 40% or more of revenue	+0.5x	FieldCamp, Home Services Business Valuation, Ad Astra Equity
Started preparing 12 to 18 months before listing	+0.5x	Home Services Business Valuation
The business depends on the owner day to day	-1.0x	Clearly Acquired, Ad Astra Equity
One customer is more than 20% of revenue	-0.5x	CT Acquisitions, Clearly Acquired, Ad Astra Equity
Half or more of revenue is new construction	-0.5x	Clearly Acquired

Multiples and adjustments read on each publisher's page on November 14, 2026. Each adjustment uses the low end of the printed range, and the three discounts were printed against EBITDA multiples. An estimate for education, not an appraisal. With scripts on, this is a calculator: set your revenue, your SDE margin and a multiple, then switch the adjustments on.

The SDE margin is the input to check hardest, because no survey prints one for HVAC. Peak Business Valuation's revenue band of 0.37x to 0.60x, divided by its SDE band, implies SDE of 15% to 18% of revenue. Your own tax return beats any default.

Above $5 million in revenue, the EBITDA bands take over

Brentwood Growth prints the fullest ladder by size. It shows the same pattern as the survey: the multiple climbs as earnings do.

Other publishers print a single EBITDA band, and they do not agree with each other.

The bands disagree most at the top. Capstone's 9.5x is a sector average, and the deals that disclose a price tend to be large. Its October residential services report cites two, at $800 million and $2.5 billion.

Even that headline number has come down. Capstone puts the 2021 to 2023 average at 13.3x.

SF&P Advisors, an advisory firm writing in a sponsored ACHR News article, calls 4x to 7x adjusted EBITDA the realistic range for an owner-operated contractor. That is the row to plan around if your company is past the SDE line.

What moves the multiple, in the order buyers rank it

A band is a range of risk. Each factor below moves a company up or down inside it, and the publishers that size the move are named. One "turn" means 1.0x of the multiple.

1. Recurring maintenance agreements. Raincatcher ranks a deep book of agreements as the biggest single lift a seller has. Three publishers size it at 0.5x to 1.0x when agreements are 40% or more of revenue. Viking adds that buyers check how many agreements renew each year, so lapsed plans earn little.
2. Owner dependence. CT Acquisitions calls it the most common discount driver in lower middle market home services deals. Clearly Acquired and Ad Astra Equity size it at 1x to 2x off an EBITDA multiple. If you sell every install and hold every relationship, what the buyer gets is a job.
3. Customer concentration. One account above 20% of revenue costs 0.5x to 1.5x in the CT Acquisitions and Clearly Acquired guides. Ad Astra Equity's safer line is no customer above 10% to 15%.
4. Service against new construction. Clearly Acquired takes 0.5x to 1.0x off when half or more of revenue is new construction. Brentwood Growth's ideal is under 20%. Viking's reason: builder work follows the construction cycle, pays slower and carries thinner margins.
5. Technician tenure. FieldCamp's benchmark is an average of three or more years. CT Acquisitions says a chronically understaffed company loses 0.5x to 1.0x during the buyer's review.
6. Clean books. FieldCamp's list is three years of tax returns, profit and loss statements, balance sheets and bank statements that agree with each other. SF&P Advisors adds accrual-basis statements, a written add-back schedule and service revenue reported apart from construction.
7. Where the leads come from. CT Acquisitions prices a single referral channel the same as a single large customer: 0.5x to 1.5x off.

Commercial work is the factor the sources split on. Home Services Business Valuation lists heavy commercial work on thin margins as a discount. CT Acquisitions gives a plumbing company a half-turn premium when 20% or more of revenue is commercial or backflow work. The margin on the work matters more than the label.

Technicians rank where they do because they are scarce. The Bureau of Labor Statistics counts 440,900 HVAC mechanic and installer jobs and projects 11% growth through 2035, with about 40,600 openings a year. A buyer who takes over a tenured crew skips that hiring line.

If agreements are your gap, the HVAC service agreement template has the auto-renewal clause and the pricing math. Start there, because it is the factor with the most published support.

Leads, the website and the phone numbers are assets too

The last factor on the list is the one marketing can move. A company that gets most of its calls from one lead vendor or one builder has the same weakness as a company with one big customer. Buyers will ask for jobs by source, so start tracking every job to its lead source a full year before you list.

Then spread the sources out. Our ranking of HVAC lead channels and the HVAC marketing plan both start with the channels you own: the Google Business Profile, reviews, the website and past customers. Housecall Pro's guide says buyers look for a steady flow of four and five star reviews.

Ownership is the quiet part. The Small Business Administration tells sellers to value intangible assets such as brand presence and customer information. A buyer can only take over what the company holds, so check who owns your website, the domain, the phone numbers and the Google profile. No publisher sizes this one.

Skill Mammoth builds websites and runs marketing for contractors and home service businesses, so read this subsection as a vendor's view. Marketing moves one factor out of seven. It does nothing for messy books or an owner who cannot step away.

Who buys an HVAC company, and what each buyer pays for

Three kinds of buyer show up, and they do not pay on the same measure.

An individual buyer usually borrows. The SBA's 7(a) loan program lends up to $5 million and lists changes of ownership as an eligible use. Clearly Acquired says the loan payments tend to cap these offers at 3.0x to 4.5x EBITDA on smaller deals.

Strategic buyers are other operating companies. Capstone Partners counted 92 HVAC services deals through July 2026, and strategic buyers made 45 of them. Privately held operators accounted for 34.

Private equity made the other 47, and 38 of those were add-ons: a smaller company bought and folded into a larger platform. Only nine were new platforms. In SF&P's example, a platform pays five to seven times earnings for a contractor with $3 million of EBITDA.

Most small companies sit below that market. CT Acquisitions says platforms compete hardest for companies with $750,000 to $3 million of EBITDA. Under that line, expect an individual or a local competitor, with the price set on SDE.

The wider market is busy. Capstone's October 2026 update counts 223 residential services deals so far this year. HVAC, plumbing and electrical companies made up 19.3% of them, second only to landscaping and lawn care.

Seven buyer searches for every seller search

We pulled a year of US Google search data for the phrases buyers and sellers type. Three buyer phrases, led by "hvac business for sale", total 3,250 searches a month. Nine seller phrases, from "hvac business broker" to "sell my hvac business", total 460.

That is about seven buyer searches for every seller search. The figure sums DataForSEO's Google Ads volumes for each phrase, with close variants that return identical numbers counted once.

Click prices point the same way. Advertisers pay $30.63 for a click on "sell my hvac business" and $1.73 for a click on "hvac business for sale". A seller is the scarce side of this market, and brokers bid like it.

Seller research also clusters early in the year. Searches for "hvac business valuation" peaked in March at 170 and bottomed in September at 40. "Hvac business broker" peaked in February at 390. Explore the monthly pattern for each phrase below.

How to sell an HVAC business: start 12 to 24 months out

Preparation is a priced factor. Home Services Business Valuation says sellers who start 12 to 18 months before listing earn multiples 0.5x to 1.5x higher.

Raincatcher says improvements take 12 to 36 months to show up in the statements buyers read. Buyers look across several years and at the trailing twelve months, so a good last quarter does not outweigh three uneven years. The plan below runs backward from the listing date.

1. 24 months out: fix the books. Move to accrual-basis statements, stop running personal costs through the company and start a written add-back schedule.
2. 18 to 24 months: build the agreement base. Add the auto-renewal clause, enroll at every tune-up and keep a list with renewal dates.
3. 18 months: hand off the relationships. Put a manager between you and the customers. A 2020 ACHR News checklist for a 5x company asks for managers with two years in the role.
4. 12 to 18 months: spread the risk. Bring any customer or lead source that dominates back under the 20% line, and move the domain, phone numbers and Google profile into the company's name.
5. 12 months: get a professional valuation. The SBA advises setting a value before you market to buyers and names three approaches: income, market and assets.
6. 6 to 12 months: assemble the file. Three years of returns and statements, the agreement list, the fleet list, contracts, leases and licenses.
7. Listing to closing: stay in the chair. Keep the numbers steady, because the buyer's accountants will recalculate your earnings before the price is final.

Licenses deserve an early look. The SBA tells buyers they need to get licenses and permits from the current owner or apply for their own. If the company's license rides on you personally, a buyer will want to know who holds it after closing.

The cost of skipping the work shows up in an older data point. An October 2020 ACHR News article by a Florida HVAC brokerage, drawing on that state's business listing data, said more than half of HVAC listings never sell. Those that sold averaged 2.3 times owner benefit.

What the sale leaves you with: terms, time and taxes

Most of the price arrives at closing. In the Market Pulse survey for the second quarter of 2026, sellers received 83% to 92% of the price in cash at close on average. Seller financing, where you carry a note for part of the price, was under 10% of most deals.

Plan for the calendar too. The same survey puts the time to close at six to 10 months for deals under $2 million and 11 to 12 months for larger ones. Housecall Pro's HVAC guide gives three to nine months.

Retirement was the leading reason owners went to market in every size band, and it reached 72% of sales in the $1 million to $2 million band. If that is your reason, buyers have seen it before.

Taxes turn on how the price is split. The IRS says the sale of a business usually is not a sale of one asset: each asset is treated as sold separately. Capital assets produce capital gain or loss, and inventory produces ordinary income or loss.

Buyer and seller must both use what the IRS calls the residual method to allocate the price, and both file Form 8594 when goodwill attaches to the assets. The allocation is negotiated. Brentwood Growth says a seller usually nets 70% to 75% of the price.

That is a description of the rules, not advice on your sale. The SBA says an attorney should review the sales agreement, and a CPA should model the allocation before you sign a letter of intent.

Plumbing and other trades: the same HVAC business valuation method, different bands

A plumbing business valuation uses the same two steps: owner earnings, then a multiple. So does every other home service trade. The bands are what change, and two publishers that print them by trade disagree in places.

For a small plumbing company, the SDE bands are tighter. Home Services Business Valuation prints 2.5x to 4.5x, half a turn under its HVAC ceiling. Viking prints 2x to 3x for smaller plumbing firms.

Pest control shows what recurring revenue does to a multiple. CT Acquisitions puts a company with mostly one-time work at 3.3x to 4.5x EBITDA. Above 80% recurring revenue, the band starts at 6x.

The lesson carries back to HVAC. Whatever the trade, the buyer is pricing how sure next year's earnings are, and a signed agreement is the best proof an owner can show.

Three things to skip

• Skip pricing off revenue. Peak Business Valuation's revenue band is 0.37x to 0.60x, wide enough to be useless alone. Two companies with the same sales can sit at opposite ends of it.
• Skip the headline multiple. The 9.5x average and the 16x and 18.5x platform deals in Capstone's reports are prices for large companies with management teams. They are not a starting point for a company priced on SDE.
• Skip signing against a calculator. Every online tool, the one on this page included, is a range for planning. A professional valuation looks at your actual statements, and an offer is the only real price.

Frequently asked questions

What multiple do HVAC businesses sell for?

Seven publishers read on November 14, 2026 print HVAC bands between 2.0 and 5.0 times seller's discretionary earnings, and the median of their midpoints is 3.0. Larger companies sell on EBITDA, where the same kind of publisher prints roughly 3 to 10 times. Capstone Partners' 9.5 times average covers announced deals, which tend to be large.

How do I calculate SDE for an HVAC company?

Start with net profit from the tax return. Add back the owner's salary and payroll taxes, personal expenses the company pays, interest, depreciation, amortization and one-time costs that will not repeat. The total is seller's discretionary earnings. Keep an invoice or statement for every add-back, because buyers remove the ones they cannot verify.

Is an HVAC business valued on SDE or EBITDA?

Size decides. The IBBA Market Pulse reports deals under $2 million in purchase price as multiples of SDE and deals from $2 million to $50 million as multiples of EBITDA. CT Acquisitions puts the switch near $750,000 of EBITDA. An owner-run company under about $5 million in revenue is usually priced on SDE.

How much do maintenance agreements add to the value of an HVAC business?

FieldCamp, Home Services Business Valuation and Ad Astra Equity each print a premium of 0.5 to 1.0 turns of the multiple when service agreements are 40% or more of revenue. On $240,000 of earnings, half a turn is $120,000. Buyers also check how many agreements renew each year, so a list of lapsed plans earns little.

How long does it take to sell an HVAC business?

Plan on 12 to 24 months of preparation, then the sale itself. The IBBA Market Pulse for the second quarter of 2026 reports six to 10 months to close for deals under $2 million and 11 to 12 months for larger ones. Housecall Pro's guide gives three to nine months for an HVAC sale.

Is a plumbing business valued the same way as an HVAC business?

Yes. The method is the same: owner earnings times a multiple, with SDE for small companies and EBITDA for large ones. The bands differ. Home Services Business Valuation prints 2.5 to 4.5 times SDE for plumbing against 2.5 to 5.0 for HVAC, and CT Acquisitions prints 2.4 to 6.5 times EBITDA for plumbing.
