HVAC business valuation multiples: what an HVAC company is worth and why

This guide is for an HVAC owner who has never sold a company and wants a straight answer on price. By the end you will know the HVAC business valuation multiples the market is paying by deal size, what sellers are asking right now, and what pushes your own number up or down. Every figure comes from one of two named sources.

Where the numbers come from

There are two honest ways to see what an HVAC business is worth: what deals closed at, and what sellers are asking. This post uses one source for each.

The first is the Q4 2025 Market Pulse from the International Business Brokers Association (IBBA) and M&A Source, a quarterly survey of brokers and M&A advisors about the deals they closed. Its multiples cover all main-street and lower-middle-market businesses, not HVAC alone, sorted by deal size, not industry.

The second is our own October 2026 asking-multiples report. Our AI sourcing agents read 15+ business-for-sale marketplaces every day. Between 1 September and 22 October 2026 they read 2,914 listings on BizQuest, BizBuySell, BusinessesForSale.com and others. The report sums up what those sellers are asking. They are asking prices, not sale prices, and "home services" there is wider than HVAC alone.

Neither source is an HVAC-only number. Together they give you a size band from closed deals and an asking range from the live market, which is a fair frame.

HVAC business valuation multiples by deal size

IBBA's Q4 2025 Market Pulse reports average multiples by purchase price for each quarter of 2025. Deals under $2M are priced on SDE (seller's discretionary earnings). Deals from $2M up are priced on EBITDA. Here is the table as the document states it.

Source: IBBA and M&A Source, Market Pulse Q4 2025 highlights. All industries, closed deals reported by brokers.

Two things stand out. The smallest deals sat at 2.0x SDE all year, while the $2M to $5M band rose every quarter, from 3.5x to 4.1x EBITDA. And the step from the $1M to $2M band to the next one is a different earnings measure, not only a bigger number.

The same report says sellers in the lower middle market got 3.61 offers per deal on average in 2025, against 2.38 for main street. More offers is one reason larger companies get higher multiples.

What HVAC and home services sellers are asking right now

Closed deals tell you what buyers paid. Listings tell you what sellers hope for. Our October 2026 asking-multiples report gives that second half.

Across all 2,914 listings our agents read, the median asking price divided by SDE was 3.04x, from the 1,282 listings that disclosed both figures. In the home services sector, which covers HVAC, plumbing, electrical, landscaping and similar trades, the median was 3.21x SDE on 27 listings, with the middle half of sellers asking between 2.62x and 4.00x. The median asking price for a home services listing was $1,225,000, from 56 listings with a disclosed price.

Read those numbers with care. Twenty-seven listings is a small sample, and sellers set these prices, not buyers. Still, the two sources agree. A home services seller asking 3.21x SDE on a business priced around $1.2M is close to the 3.1x IBBA reports for Q4 2025 deals of that size.

SDE or EBITDA: which one applies to you

Small HVAC companies are valued on SDE and larger ones on EBITDA, and the line between them is roughly the $2M purchase price IBBA uses.

SDE is the business's profit plus the owner's salary, benefits and personal expenses run through the company. It assumes the buyer will step into the owner's job. A one-truck or five-truck shop where the owner runs dispatch, sells the big jobs and holds the licence is an SDE business.

EBITDA leaves a market-rate manager's salary in the costs. It assumes the buyer is an investor who will hire or keep a general manager. A $4M HVAC company with an operations manager, a service manager and a sales lead is an EBITDA business, and the buyer will price it that way.

EBITDA is a smaller number than SDE for the same company, because a manager's pay has been taken out. So a 4.1x EBITDA multiple is a higher multiple on a smaller base. Our SDE to EBITDA calculator shows both figures for your own numbers.

Whichever measure applies, the add-backs have to be real. A buyer's lender will check them.

What pushes an HVAC company up the range

Within any size band there is a spread: the middle half of home services sellers in our report asked anywhere from 2.62x to 4.00x SDE. These things move an HVAC business toward the top of its band.

Maintenance agreements. A base of customers paying a yearly service fee is recurring revenue. It fills the shoulder seasons, it feeds replacement sales, and it transfers to a new owner. Buyers count the agreements, check the renewal rate and look at what share of revenue they bring in.

Residential replacement and service. Repair and replacement work for homeowners is steady, high-margin and spread across many customers. It is worth more than new construction work.

A licensed team, not a licensed owner. If a technician or manager other than the owner holds the mechanical licence, the business can run without the seller. That removes a buyer's biggest worry.

Technician count and tenure. More technicians with longer service means capacity and less key-person risk. Buyers ask how many are certified and how long each has been there.

Clean books. Three years of tax returns that agree with the profit and loss statement, a job-costing system and accounts kept by an outside bookkeeper. Clean books speed up diligence and support the add-backs. We cover the full list of what a buyer pays extra for in what buyers pay a premium for.

What pulls an HVAC company down the range

The same list works in reverse, with a few more items.

Owner dependency. The owner is the only licensed contractor, the only estimator and the person every customer asks for. A buyer either prices in a long transition and a hire, or walks away.

New construction and builder concentration. Install work for builders comes in large contracts, at thin margins, and it stops when housing starts stop. One builder over a quarter of revenue is a concentration risk, and buyers lower the price for it.

Old fleet and equipment. Worn trucks, worn tools and a shop that needs work mean cash the buyer must spend on day one. That cash comes off the price.

Seasonality with no plan. Every HVAC company is seasonal. One that lays off technicians every winter looks weaker than one with maintenance agreements and a steady crew.

Messy records. Cash jobs, personal spending mixed with business spending, and add-backs the owner cannot prove. Each one makes a lender nervous, and most buyers under $5M need a lender.

Why private equity pays more for larger HVAC companies

The IBBA table shows the $5M to $50M band at 5.5x EBITDA, well above the 4.1x of the band below it. Private equity is a large part of the reason, and it is now active in HVAC in small towns, not only in big cities.

A private equity firm buys one HVAC company as a platform and then adds smaller ones nearby, keeping each local name and leader. One example is TruTemp's purchase of D&D HVAC and Sandhills in North Carolina in October 2026. The price was not disclosed, so it shows the pattern, not the multiple.

A platform can pay more for a larger company because it plans to resell the combined group later at a higher multiple than it paid for each piece. That is why the biggest band in the IBBA table pays the most. If you would rather be the buyer in that story, read how to start a home services roll-up.

For a company under $2M, platforms are usually not your buyer. Your buyer is an individual with an SBA loan, a seller note and some cash, and the price has to work on those terms.

A worked example

Here is an illustration with round numbers, not a quote. It uses the IBBA Q4 2025 average for the band each company lands in. Your own company will sit above or below that average for the reasons above.

The small shop lands inside the $1M to $2M band at 3.1x, so the band and the price agree. If the owner holds the only licence and half the revenue is builder installs, a buyer will argue for the bottom of the range. If a service manager holds the licence and hundreds of maintenance agreements renew each year, the owner can argue for the top.

The mid-sized company is worth about four times the small one. The extra comes from the higher multiple and a buyer pool that includes platforms. Put your own numbers into our business valuation calculator to see where you land.

What to do before you sell

An HVAC owner who starts two years before selling can move the multiple.

1. Get a second licence holder in place and let that person run jobs without you.
2. Grow the maintenance agreement base and track the renewal rate.
3. Shift the mix toward residential service and replacement if builders are more than a quarter of revenue.
4. Clean the books: outside bookkeeper, tax returns that match the P&L, no personal spending through the company.
5. Replace or plan for the oldest trucks so the buyer does not price them in.
6. Get a valuation on both SDE and EBITDA so you know which buyers you are talking to.

We help owners do this and then sell for a higher price. Moran Pober has advised buyers and sellers of small and mid-sized businesses since 2016, and HVAC is one of the sectors we see most. See how we help you sell or read the full process in how to sell a business.
