# Buying an HVAC Business

What HVAC shops trade for, why the service-to-install mix decides the multiple, and how the license qualifier and the A2L refrigerant switch shape a deal.

## Why Searchers Target HVAC

HVAC combines the traits the roadmap's thesis stage tells you to look for: recurring, weather-driven demand; a fragmented base of owner-operated companies; and a large cohort of founders reaching retirement. [Private equity](https://searchspheresource.com/glossary/private-equity) consolidators have spent years rolling up the category, which validates the economics and provides exit paths, but it also means clean companies attract professional competition. Expect to win on speed, fit, and seller trust rather than price.

## What the Market Pays

Across HVAC businesses sold on BizBuySell from 2021 through 2025, the sold-business quartiles ran 2x to 3.3x [SDE](https://searchspheresource.com/glossary/sde) with the median at 2.6x, and asking prices ran about half a turn above what sales closed at. The single biggest lever is [revenue mix](https://searchspheresource.com/glossary/revenue-mix): businesses with a meaningful base of maintenance agreements command a premium over install-heavy peers, because recurring service revenue survives the owner transition better than one-time replacement work. Treat any multiple quoted without the install-versus-service split as unpriced.

## Licensing and the Qualifier Question

Most states require HVAC work to run under a licensed contractor of record, often called a qualifier. If you do not hold the license, the deal depends on a qualifier arrangement: the seller staying on in that capacity for a period, a licensed employee assuming it, or you earning it, and state rules differ on timelines and transferability. Confirm the licensing plan in writing before the [LOI](https://searchspheresource.com/glossary/loi), since it affects closing timing, SBA eligibility, and how much the seller transition is really worth. One federal rule outranks the state license here: a company may buy refrigerant only if it employs a certified technician, and that certification belongs to the person. Buy the assets, lose the crew, and the trucks cannot be restocked.

## The Refrigerant Transition Is a Diligence Item

The industry is mid-transition to A2L refrigerants under the federal AIM Act. Reporting through 2025 describes sharp price rises and supply constraints for the new refrigerant and its cylinders, tooling and training. This cuts both ways: replacement demand rises as older systems age out, but quotes and margins written before the cost spikes may not survive them. Ask about refrigerant inventory, A2L tooling, and how price rises pass through open bids.

## What to Verify in Diligence

Beyond the standard [QoE](https://searchspheresource.com/glossary/qoe) work, the HVAC-specific list is:

## Financeability Notes

HVAC fits [SBA 7(a)](https://searchspheresource.com/glossary/sba-7a) financing well: steady cash flow, tangible fleet and equipment, and deal sizes inside the program cap. Lenders will focus on owner dependence, especially when the seller is also the license qualifier, and on whether earnings cover debt service after a market-rate manager replaces whatever the owner personally does. Run the numbers in the SBA calculator with a realistic salary for the role you are actually taking, and pressure-test the [DSCR](https://searchspheresource.com/glossary/dscr) against the seasonally weakest quarter.

## Terms in This Industry

- **Callback rate**: The share of jobs that bring a technician back for the same fault, unpaid. It is the cleanest read on install quality there is, and it comes straight out of the dispatch software, not out of a conversation. Every callback is a truck roll and a technician-hour billed to nobody, so a shop running high is losing margin twice: once on the return and again on the reviews. Ask for callbacks as a share of completed jobs by technician, because the number is usually one or two people and not the whole crew.
- **A2L refrigerants**: The lower-global-warming refrigerants replacing the old ones, which changes equipment and training. The transition is a real cost and a real opportunity at once: new equipment lines, retrofit rules, and technician certification. Ask what the truck stock and the training records actually look like, because a shop that has already moved has spent money you do not have to spend, and one that has not is carrying an expense that arrives on your watch. It also decides which jobs the crew can legally take next season.
- **License qualifier**: The named individual whose contractor license the business legally operates under. If the qualifier is the seller, the license loses its qualifier at closing, and states give only a short window to name another: ninety days in California and sixty in Florida. A buyer either becomes the qualifier, which usually means years of documented experience and an exam, or hires one and keeps them, which is a salary and a retention problem, not a signature. Settle which of the two it is before the LOI, because the answer can change the price or end the deal.
- **Maintenance agreement**: A contract for scheduled seasonal service, which buys predictable revenue and the first call. Maintenance agreements are the recurring, higher-margin core underneath a lumpy install business, and their count and renewal rate are much of what separates a 2x shop from a 4x one. Count them yourself against the invoices rather than the seller's summary, and check whether they transfer or need each customer's consent. Ask what happens at renewal too: a book sold on a discounted first year renews at a number nobody has tested.
- **Classification boundary**: Where the heating and cooling license stops and another trade's license starts. Three edges catch buyers. California puts refrigeration below fifty degrees in its own classification, so a company servicing walk-in coolers alongside rooftop units may need two. Gas fuel lines inside a building sit with plumbing in that state, and Florida writes the same carve-out from the other side, excluding fuel gas lines from the air-conditioning contractor's scope except for a straight appliance changeout. And the federal refrigerant certification belongs to the technician who could break into the circuit, not to the company, so it walks out of the building with whoever holds it. Read the work orders against the classifications before assuming one license covers the book.
- **Manufacturer dealer agreement**: Wisconsin's dealership law can grant a right to sell a line with nothing signed, and it may not transfer. Wisconsin's dealership law carries no product limit: a dealership is any contract or agreement, expressed or implied, oral or written, granting a person the right to sell or distribute goods, where a community of interest exists. No grantor may terminate, fail to renew or substantially change the competitive circumstances without good cause, the burden of proving it sits on the grantor, and ninety days' notice with sixty to cure is owed. The chapter's effect may not be varied by contract. Its reach over this trade is settled: the state's supreme court sent a distributor's claim to a jury against a Madison maker of humidifiers, air cleaners and thermostats, on a relationship with no written agreement at all. So diligence reads the course of dealing, and the risk at closing runs the other way from the one buyers expect: a transfer can extinguish the protection the seller enjoyed.
- **Certification type**: Which class of appliance a technician's federal refrigerant card lets them touch. The guide already says the refrigerant credential belongs to the person and not the company. What it does not say is that the card comes in grades, and the grade decides which work the crew may take. Type I covers small appliances, Type II the medium, high and very high pressure equipment, Type III the low pressure machines, and Universal all of them. A shop full of Type I cards cannot lawfully take the rooftop and chiller work its own profit and loss is built on. Two more things sit in the same rule and neither is on the shelf. An apprentice may work under a certified technician who is closely and continually supervising and who shares the responsibility, which is the staffing lever a growing shop actually pulls. And a distributor may only sell refrigerant to a company that can show it employs a certified technician, keeping that proof and the invoices for three years, so a supply relationship is a document a buyer can ask to see.
- **Flat-rate book**: The priced task list a technician quotes from at the door, in place of hours and parts. A shop on flat rate sells a repair at a published price, so its gross margin is set in the office and not at the kitchen table, and two technicians of different speed earn the shop the same money on the same job. A shop still on time and materials is exposed to whoever is holding the wrench. Ask which book the shop prices from, when those prices were last updated, and whether a technician may discount without a manager. A book three years stale is a margin problem wearing a pricing policy.

## How Big This Market Is

There are about 111,207 businesses in this industry. 44,680 of them (40%) have 5 to 99 employees: the band big enough to have something to sell, small enough to finance. Most of the rest are owner-operators with a job rather than a business to hand over. Census County Business Patterns (2023); how often they change hands is on https://searchspheresource.com/data/market-depth.

## Who the Law Lets Own This

Most states require a licensed qualifier to hold the contractor license the business operates under.

How buyers structure around it: Employ or retain a qualifying license holder; buyer licensure timelines vary by state.

Most of these rules are set state by state and change, so confirm the current one with the regulator that issues it and an attorney (https://searchspheresource.com/data/license-rules).

## What It Costs to Replace the Owner

The multiples are quoted on SDE, which adds the owner's pay back into earnings, so they hold only if you do the owner's job. For this trade the replacement is usually the lead who runs the trade crews, paid a median of $93,320 a year nationally; at a 3x multiple that wage takes about $279,960 off what the business is worth to you. First-line supervisors of construction trades and extraction workers, BLS Occupational Employment and Wage Statistics (2025), within plumbing, heating, and air-conditioning contractors specifically, before payroll taxes and benefits (https://searchspheresource.com/data/manager-wages).

## How Often These Loans Go Bad

Of the 137 SBA acquisition loans in this industry old enough for most failures to have shown up, 7 were charged off: a rate of 5.11%. Across every industry measured, the pooled rate is 4.20%, so this one runs hotter than the average acquisition. Computed from SBA loan-level data on a seasoned cohort; it counts loans already written off, so read it as a floor and as a ranking (https://searchspheresource.com/data/sba-default-rates).

## The Numbers That Run This Business

- Service-agreement revenue share
- Booked calls versus technician capacity
- Average ticket by job type
- Maintenance-agreement renewals
- Install backlog and close rate
