What should you know before buying an HVAC business?

What is in the price of an HVAC business?

The 2.79x average is a multiple of SDE: profit before one owner's salary and benefits, interest, depreciation and amortization. It is an average across many deals. A specific shop can sit well above or below it.

The multiple climbs with size. Practitioner estimates for 2026 put HVAC and plumbing businesses at:

• Owner-run shops: 2.0x to 3.5x SDE.
• Companies with $3 million to $10 million of revenue: 5x to 8x EBITDA.
• Regional platforms with more than $25 million of revenue: 9x to 13x EBITDA.

Note the switch from SDE to EBITDA. Above roughly $1 million of earnings, buyers treat the owner's salary as a cost and price on EBITDA, and multiples rise. Our article on SDE vs EBITDA shows the arithmetic.

Within a size band, these features usually push a shop toward the top of its range:

• Service agreements. Maintenance plans renew and feed replacement work. Ask how many there are, the renewal history and whether they are prepaid.
• Residential replacement and service rather than new-construction installs, which depend on a few builders and the housing cycle.
• A technician bench that does not depend on the owner, with a service manager or dispatcher who runs the schedule.
• Clean fleet and equipment records. Find out which trucks are included, which are financed and what liens come off at closing.

Ask early what the price includes. Parts inventory, vehicles and working capital are handled differently from listing to listing. Our article on what is included in the multiple covers the usual treatment.

What kills HVAC deals?

• The license walks out with the seller. If the seller is the company's licensed qualifier and nobody else holds the license, the business may not be able to pull permits after closing.
• The owner is the salesman. If the owner runs every replacement quote, revenue can fall when the owner leaves. Test it: ask who closed each of the last 50 replacement jobs.
• Technicians leave. Skilled technicians are hard to replace. Meet the lead techs before closing, and plan pay and retention before the announcement.
• Customer concentration in builders or one commercial account. See how much concentration is too much.
• Warranty and callback exposure. Ask for the callback log and any open warranty claims. In an asset purchase, decide in the purchase agreement who covers work done before closing.
• Coverage fails. SBA lenders require 1.25x debt service coverage on historical cash flow for a first acquisition. A strong 2026 forecast does not count.

What licensing should you check?

Many states license HVAC contractors, often through a qualifying individual tied to the company. Rules vary by state and sometimes by city or county. Before you sign a letter of intent, check:

• Who holds each license the company operates under, and whether it belongs to the company or to a person.
• Whether a licensed employee can serve as qualifier after closing, and what the board requires to change the qualifier.
• Whether you plan to get licensed yourself, and how long that takes in your state.
• Technician certifications. Technicians who handle refrigerants need federal EPA certification. Ask for copies.

If you are using an SBA loan and do not hold the license yourself, read whether you need a trade license to buy with an SBA loan. Confirm the structure with your lender and your state licensing board before closing.

Leases matter less in HVAC than in retail, because customers do not come to the shop. Still confirm the shop and yard lease can be assigned to you or renewed, and that the term covers your plans.

How does private equity competition change the deal?

PE firms are active in HVAC, mostly through add-ons. Of 25 HVAC deals PKF O'Connor Davies tracked in the first half of 2026, 14 were PE add-ons and 3 were new PE platforms. Carta data from September 2026 shows HVAC add-ons running roughly four times as common as platform deals, and PE home-services deal count rose 150% from 2020 to 2024.

This cuts two ways for you:

• If you are buying your first business, the smallest owner-run shops still trade near Main Street multiples. Larger shops with a management layer attract PE buyers, and prices move toward EBITDA multiples.
• If you already own a business, the spread between a 2.0x to 3.5x SDE shop and a 9x to 13x EBITDA platform is the reason PE buys add-ons. You can run the same play. Every shop you add and integrate makes the whole worth more, if you do not overpay and the integration works. See the multiple difference between an add-on and a platform.

Worked example: does an HVAC deal cover its debt?

Illustrative numbers, using a simplified version of the lender's coverage test:

1. SDE: $600,000. Price at 2.79x: $1,674,000.
2. Add working capital of $100,000 and fees and closing costs of $50,000. Total project cost: $1,824,000.
3. Minimum equity injection at 10% of total project cost: $182,400.
4. SBA loan: $1,641,600, amortized over 10 years at an assumed 10% rate. Annual debt service: about $260,300.
5. Subtract a $120,000 salary for you as operator. Cash available for debt service: $480,000.
6. Coverage: $480,000 divided by $260,300 is about 1.84x. That clears the 1.25x test.

The deal pencils at the average multiple. Rerun it if the owner is the only licensed person and you must hire a qualifier and a general manager. A $150,000 manager in place of your $120,000 salary still leaves coverage near 1.73x. The bigger risk is revenue falling after the owner leaves. A 20% drop in SDE, to $480,000, leaves $360,000 after your salary and coverage near 1.38x. That still clears the test, with little room left.

Where these numbers come from: HVAC and all-sector SDE multiples are BizBuySell data for 2021 to Q1 2026 as summarized by Beancount. Size-band ranges are practitioner estimates from Beancount's HVAC and plumbing roll-up guide. Deal counts are from PKF O'Connor Davies' Summer 2026 HVAC M&A update and Carta. SBA rules are SOP 50 10 8.1, summarized by Beancount. The 10% rate is the SBA maximum variable rate for loans over $350,000 with prime at 7% in September 2026, per NerdWallet. Check current prime. SOP 50 10 8.1 applies to loans numbered on or after October 1, 2026; lender practice under it is still settling and these are secondary summaries, so confirm current terms with your SBA lender.

Related questions

Can I buy an HVAC business if I am not a technician?

Yes, if a licensed person can qualify the company after closing and the lender accepts that structure. Many owners of larger shops do not work on equipment. You do need to understand pricing, dispatch and technician pay well enough to manage them.

Are plumbing and electrical businesses priced the same way?

The practitioner estimates above cover HVAC and plumbing together. The same logic applies: owner-run shops trade on SDE, larger companies on EBITDA. Licensing questions are similar but the boards and rules differ.

Will PE buy my HVAC company later?

PE buys HVAC shops as add-ons today, per the PKF and Carta data. Whether they buy yours depends on size, margins, management and the market when you sell. Build the company so it is worth owning without a sale.

What comes next

An HVAC shop is the classic first add-on in a home-services roll-up. Before you price one, read what the multiple difference is between an add-on and a platform, because that gap is where a holding company makes its money.
