How to sell an HVAC business
Selling an HVAC business follows a predictable arc. Expect six to twelve months from the day you decide to sell to a funded close, with most of that time spent preparing financials and fielding buyer interest. Once a buyer signs a letter of intent, the LOI-to-close stretch (due diligence, financing, and legal) usually runs four to six months. The cleaner your books and the less the business depends on you personally, the faster it moves.
Who buys matters as much as what you built. An individual operator or self-funded searcher typically pays 2.5-4.5x SDE and may rely on SBA financing. A search fund generally pays around 3-5x EBITDA, while a private-equity roll-up pays roughly 4.0-7.0x EBITDA and often structures the deal as 60-80% cash at close, with the balance in an equity rollover, seller note, or earnout. A strategic acquirer already in the trades can stretch toward 5-10x EBITDA when your service area or commercial book fills a gap for them.
For HVAC specifically, buyers pay up for recurring revenue and transferability. Maintenance agreements and service contracts that renew automatically are worth more than one-off installs because they make next year's cash flow predictable. A roster of licensed, tenured technicians, a documented dispatch and pricing system, a maintained fleet, and a healthy mix of replacement and service work (rather than thin-margin new construction) all lift your multiple. A general manager who runs day-to-day operations is often the single biggest factor in where you land within the 4.0-7.0x range.
Plan for taxes before you sign anything. Most of your gain is taxed at long-term capital-gains rates of roughly 15-20% federal, plus the 3.8% net investment income tax for higher earners (which generally does not apply if you materially participate in the business) and any state tax; asset sales usually fall less favorably on the seller than stock sales. DealSeam works the buyer-paid side of this market: we match owners with vetted acquirers where there's a genuine fit, and sellers pay nothing. We never promise a specific buyer or price, but we help you understand what your shop is worth and who is actually looking.
Related questions
What number do HVAC buyers focus on most?
Normalized cash flow. For owner-operated shops buyers work from seller's discretionary earnings (SDE) at about 2.5-4.5x; for larger, manager-run companies they use EBITDA at about 4.0-7.0x. Both start from your real earnings after adding back owner salary, personal expenses, and one-time costs.
Do recurring maintenance contracts really change my price?
Yes. Auto-renewing service agreements create predictable revenue, which buyers value far more than one-time installs. A solid book of active maintenance contracts can move you toward the top of the range and shorten diligence.
How long does selling an HVAC business take?
Plan on six to twelve months overall, with roughly four to six months between a signed letter of intent and closing once a buyer is committed and financing is in place.
Will I have to stay on after the sale?
Often briefly. PE and search-fund buyers frequently ask for a transition period and may tie part of the price to an earnout or seller note, especially if you're still central to operations. A strong second-in-command reduces this.
What does DealSeam charge me as a seller?
Nothing. DealSeam is compensated by buyers on closed deals, so owners can explore a sale and see qualified interest without paying a commission. A traditional broker, by contrast, typically charges sellers 8-12% (with a $10-15k minimum).
