HVAC Business Valuation Calculator
What Is Your HVAC Business Worth, and What Makes It Worth More?
If you plan to sell your HVAC business in 2 to 5 years, the price is being set now. Every HVAC business valuation comes down to adjusted EBITDA times a multiple, and the multiple moves on a handful of things you control. Put in your numbers and see what the company is worth today, what it could be worth, and which levers close the gap.

Worth today, estimated
How the valuation works.
Worth today
Adjusted EBITDA times a multiple. The multiple comes from real HVAC deals at your size, then moves up or down the range based on how many of the six drivers are green. New construction at 40% or more takes about 1.5 turns off.
Worth with the levers fixed
Same revenue, margin raised to about 20% if it is below that, all six drivers green. No growth assumed. This is the price the company you already have could command if a buyer could underwrite it.
Numbers for your price
Your target divided by the fixed-lever multiple gives the EBITDA you need. Divide by margin for revenue, then spread it across the years you have left. That is the scoreboard for the next 2 to 5 years.
Getting ready to sell: the 2 to 5 year runway.
This is how we sequence it. The slowest levers go first, because a buyer wants to see them working for years, not months.
Year 1
Take yourself out of it
Hire or name the manager. Move replacement sales to a process your team runs. Get off the tools. Clean the books and document every add-back so a buyer can verify it. Start tracking recurring share and turnover monthly.
Years 2 and 3
Build the trend line
Grow maintenance agreements and service revenue. String together years of 10%+ growth. Lift margin toward 20%. This is where marketing, the phone, and follow-up earn their place, because a buyer reads growth from your job records, not your pitch.
Final 12 months
Make it easy to buy
Get the financials ready for a quality of earnings review. Fix any customer or builder concentration. Know where multiples sit in the market before you go, because they move with the deal cycle.
What this calculator leaves out.
On purpose, so you know where the number is soft.
- It is an estimate, not an appraisal
- A buyer’s number comes from due diligence on your books. Use this to see which levers move the price, not to set one.
- Where you sit in the range is our method
- The size ranges come from real HVAC deals. How far up the range six green drivers move you is our judgment, and we stop halfway between the median and the top, because the top is usually a competitive sale to a platform.
- Debt, working capital, and terms
- Enterprise value is before debt, fees, and how the price is paid. Cash at close, earnouts, and rollover change what you take home.
- Very small shops
- Under about $1M in earnings, many deals are priced on seller’s discretionary earnings instead of EBITDA. The add-backs field covers most of the difference.
Bring it to me before you bring it to a buyer
Most owners find out what the company is worth the month they decide to sell. By then, the levers that move the price take years. If you are thinking about selling in the next few years, text me the result and tell me what you want the number to be. I will tell you straight whether the path is there and what it takes.

HVAC Growth Audit. Free.
Want the growth side run on your real records?
A buyer reads growth from your job records. The Growth Audit works on what your call log and job software actually say, by channel, and shows which of the seven steps between a search and a booked job is leaking, which is usually the fastest EBITDA an owner can add before a sale.
- Cost per booked job, by channel, from your own numbers
- The step that is leaking, and how many jobs it costs you
- What it takes to move it, and the next step if you want one

HVAC valuation multiples and what buyers pay for.
A buyer is not paying for last year. They are paying for next year, the year after, and how sure they can be about both. That is why two HVAC companies with the same profit can sell for very different prices, and why the valuation multiple matters as much as the earnings. Axial’s HVAC deal data puts the median at 3.12x EBITDA for companies under $1M in EBITDA and 7.02x for companies over $5M, with wide ranges inside each band. Where you land inside the range is the part you control.

The market has also cooled from the peak. Capstone Partners reports HVAC services deals averaging 9.5x EBITDA from 2024 through mid-2026, down from 13.3x in 2021 to 2023, with most private equity activity now in smaller add-on acquisitions. Buyers are paying less for the same earnings, so the drivers that move a company up its range matter more than they did.

The drivers are consistent across sources. Service and repair revenue commands the highest premium because it repeats and carries margin. Ten percent growth for three straight years is worth meaningfully more than flat or volatile revenue. New construction above 40% of revenue compresses the multiple by 1 to 2 turns. And an owner who is the top technician, the head salesperson, and the main customer relationship is key-person risk that a buyer prices in.

Most of those drivers are built, not bought, and they are the same things we work on with owners across HVAC contractors we grow of every size. Recurring revenue comes from a maintenance agreement offer on every call and follow-up that keeps customers from shopping, the work maintenance agreement follow-up campaigns are built for. Growth that a buyer believes shows up as booked jobs by channel, which is what lead generation built on your own tracking gives you. And margin starts at the job level, which the job-level margin calculator breaks down one ticket at a time.
The runway matters because the buyer is reading years, not months. The Exit Planning Institute reports that only 20% to 30% of businesses that go to market actually sell. The ones that do usually started getting ready long before they listed. If you are on the other side of the table, the private equity value creation calculator runs the same levers as a buyer sees them.

Questions owners ask.
How much is my HVAC business worth?
Adjusted EBITDA times a multiple. For HVAC, Axial’s deal data shows medians from about 3x for companies under $1M in EBITDA to about 7x over $5M, with wide ranges. Where you land depends on recurring revenue, growth, owner dependence, management, and retention. Run the calculator with your own numbers for a starting estimate.
How do I value my HVAC business?
Start with net profit, add back interest, taxes, depreciation, owner pay above what a manager would cost, and one-time or personal costs. That is adjusted EBITDA. Multiply it by the multiple for your size band, then move up or down the range based on recurring revenue, growth, owner dependence, management, and technician retention. That is the method this calculator runs.
How much is an HVAC business with $1 million in sales worth?
Buyers price earnings, not sales. At a 20% EBITDA margin, the home services benchmark, $1 million in sales is $200,000 in adjusted EBITDA. Axial’s HVAC data puts companies under $1M in EBITDA at a 3.12x median, with a range of 2.08x to 6.11x, which is about $416,000 to $1.2 million, and about $624,000 at the median. At this size many deals are priced on seller’s discretionary earnings instead.
How much are HVAC companies selling for?
It depends on size. Axial’s data shows medians from 3.12x EBITDA under $1M to 7.02x over $5M. Capstone Partners reports HVAC services deals averaging 9.5x EBITDA from 2024 through mid-2026, down from 13.3x in 2021 to 2023. Those larger deals pull the average up.
What are add-backs?
Costs a buyer will not carry after the sale. Owner pay above what a manager would cost, personal expenses run through the company, one-time legal or consulting fees, plus interest, taxes, and depreciation. Every add-back needs a paper trail, because the buyer will check each one.
How do I sell my HVAC business?
Get it ready before you list it. Take yourself out of the field and out of sales, put a manager in place, clean the books so every add-back can be verified, and build a record of growth and recurring revenue. Then pick an advisor or broker and time the sale to the market. The runway above is the order we work in.
How long does it take to get ready to sell?
Plan on years, not months. The levers buyers pay for most, like a manager who runs the day to day and a record of steady growth, only count once they have been working for a while. That is why the calculator asks when you want to sell and spreads the growth you need across that time.
Should I grow revenue or margin first?
Usually margin and recurring revenue first, because both raise the multiple as well as the earnings. Growth that comes with thin margin and one-time work adds less to the price than it looks like on the top line.
What does it cost?
We start from your number, not a package. Tell me what you want to invest, and I will walk you through what it buys and what it does not. If I can help, I will tell you. If I cannot, I will tell you that too, straight. Our fee is 1 flat monthly number in your proposal, always separate from ad spend so you can see what you are paying for.
Do you save what I type in here?
No. The math runs in your browser and nothing is sent anywhere unless you tap the text button, which opens a message you can edit or delete before sending.
Can I just text instead?
Yes. Text the question and I will answer it. No call, no charge. The call exists for the questions that need your numbers in front of both of us.
