What are the steps to sell my HVAC company?

Here is how to sell an HVAC business without leaving money on the table: start early, fix the few things buyers check first, and know which buyer fits your size before anyone calls. Contracting Business advises owners to start at least three years ahead. That sounds like a long time until you see the stakes: First Page Sage found that about 52% of HVAC companies that go to market do not sell, mostly because of owner dependence and customers leaving.

This guide is the HVAC version. For the general sale process (advisors, letters of intent, diligence, closing), read how selling a business works alongside it.

The plan at a glance

Step 1: Get a baseline number (36 months out)

You can't fix what you haven't measured. Work out your seller's discretionary earnings (SDE): profit plus your own pay, interest, depreciation and one-time or personal costs. For context, BizBuySell's HVAC sold deals from 2021 to 2025 had a median of 2.58x SDE, with the middle half between 1.99x and 3.33x. Bigger shops with managers are priced on EBITDA instead, and on Axial's network HVAC letters of intent ran from 2.1x to 10.9x EBITDA.

Our free HVAC estimate gives you both numbers as an illustrative range and names your top 3 value drags. It takes about 5 minutes and asks for an email on the last step so we can send the result. Then list your add-backs with the HVAC add-backs checklist.

Step 2: Make your books buyer-ready (36 months out)

Buyers pay for earnings they can verify. Next Era Legal says more granular, auditable numbers mean a higher multiple. What that means in practice:

• Have a CPA prepare at least 2 to 3 years of accrual statements that tie to your tax returns.
• Split revenue into service and repair, replacement, new construction, maintenance members and commercial.
• Stop running personal costs through the company, or at least keep a clean list with receipts.

SBA lenders check seller numbers against IRS transcripts, so income that isn't on your returns won't count toward your price.

Step 3: Solve the license and qualifier (36 months out)

In most licensed states the HVAC license belongs to a qualifying person, not the company. If that person is you, the license walks out the door with you. A few rules that show how much this varies:

• Florida: a business has 60 days to replace a sole qualifier after they leave.
• California: the qualifier (RMO or RME) must be replaced within 90 days, and a sole-owner license cannot be sold.
• Texas: license numbers are not transferable, and a temporary license is not available to a new unlicensed owner.

Your options are a licensed employee ready to qualify, an employee who can pass the exam within 12 months, staying on as qualifier for a while after closing, or a buyer who brings their own. Start the first two now, because exams and experience requirements take time. Platforms often have their own qualifier; individual buyers without a license are hit hardest. State details are on the Florida, California and Texas pages.

Step 4: Clean up your maintenance member book (24 to 36 months out)

Buyers pay most for recurring revenue. Next Era Legal calls maintenance members the single biggest multiple driver and treats 30% or more of revenue from preventive maintenance as the premium level. Its worked example: adding $100K of agreement revenue added $200K to $300K of value.

What buyers check:

1. Count: active members, not everyone who ever bought a plan.
2. Renewal rate: of members due to renew, how many did. One vendor benchmark puts monthly auto-billed plans at 90% to 95% renewal, against 75% to 85% for annual billing.
3. Visits owed: members who paid up front for visits you haven't done yet. Buyers expect credit for those at closing, so know the number.
4. Replacement link: how much replacement revenue came from members.

Move members to monthly auto-billing, track renewals in your field software, and clear the backlog of unperformed visits. The full detail is on what maintenance agreements are worth.

Step 5: Cut your new construction share (24 to 36 months out)

New construction is project work, lower margin and tied to the building cycle. Next Era Legal says companies with more than 60% new construction trade at the low end of the range. PKF reports that buyers often accept new construction of 20% to 30% of revenue. We estimate a builder-heavy mix (over 50%) costs about 0.5x to 1.0x SDE. Illustrative estimate

You don't have to drop your builders. Grow service, replacement and member work around them so the share falls, and show the split clearly in your books.

Step 6: Take yourself out of the daily work (24 to 36 months out)

Owner dependence is what Next Era Legal says most directly limits your valuation. If you sell most replacements, run dispatch and hold the license, a buyer is buying a job. A service manager, an install manager or a strong office manager is what moves a company from SDE pricing to EBITDA pricing. Train someone to run sales calls and the schedule without you, then take a two-week vacation and see what breaks. Our owner dependence test shows where you stand.

Step 7: Check dealer and distributor relationships (12 to 24 months out)

Factory-authorized dealer status (Carrier, Trane, Lennox, Mitsubishi and others) brings better equipment pricing, co-op marketing and warranty support. Dealer agreements are not always assignable on a change of control, and losing a key one can hurt equipment pricing and warranty support. Do three things:

• Find out whether the status is in your name or the company's.
• Ask your distributor rep, in writing, what happens to it if the company is sold.
• Pull your co-op balances, rebate terms and any credit line guarantees you signed personally.

Step 8: Lock in your techs and finish the refrigerant change (12 to 24 months out)

Buyers are, in Next Era Legal's words, "purchasing labor capacity as much as they are purchasing revenue". Write down pay plans, consider retention bonuses tied to the sale, and keep EPA 608 certifications on file.

New split systems installed after January 1, 2026 must use a refrigerant with a GWP under 700. Buyers will check that your techs are trained, your tools are A2L-rated and you are not sitting on old stock you can't sell.

Step 9: Pick your buyer types and advisors (6 to 12 months out)

Your size decides who calls back. PE add-on buyers generally want about $1M or more of EBITDA and new platforms $5M or more. Below that, most buyers are individuals and local competitors. See who buys HVAC companies for every buyer type side by side.

Most owners hire a business broker or M&A advisor. Fees are usually a success fee: one trades broker publishes $100,000 on a $1M sale and $180,000 on $2M. In 17 states business brokers must hold a real estate license, and Illinois requires registration with the securities regulator instead. This is not legal advice; ask an attorney in your state. You will also want a CPA who has done business sales and a deal attorney.

Step 10: Offers, diligence and closing (0 to 6 months)

A letter of intent sets price and terms, then due diligence tests everything. A quality-of-earnings provider will test each add-back. Expect questions on member counts, labor warranties you sold, fleet age and your top customers.

Read every offer for what you get at closing, not the headline.

Common mistakes

• Starting when you're already tired. A rushed sale gives the buyer the upper hand.
• Counting members you can't prove. If renewal isn't tracked, buyers won't credit the book.
• Forgetting the license until the letter of intent. In Florida or California the clock starts the day the qualifier leaves.
• Mixing personal costs into the books with no list. Every add-back without a receipt is at risk.
• Assuming dealer status transfers. Ask your distributor before a buyer does.
• Judging offers on the headline. Cash at closing, notes, earnouts and debt payoff decide what you keep.
• Telling your team too early, or too late. Decide with your advisor when and how key people hear.

Questions to ask your CPA, attorney or broker

1. Are my books ready for a quality-of-earnings review, and what will it flag?
2. Which of my add-backs will a buyer accept, and what proof do I need?
3. Who can qualify the company's license after I leave, and how long does that take in my state?
4. How should prepaid maintenance visits be handled at closing?
5. Is my dealer agreement in my name or the company's, and can it be assigned?
6. Asset sale or stock sale: what does each mean for my license, contracts and taxes?
7. Which buyer types fit my size, and how many will you contact?
8. What is your fee, what does it cover, and are you licensed or registered in my state if required?
9. How much would I keep after debt, fees and taxes on this offer?
