04 May How to Value an HVAC, Plumbing, or Trade Business
If you own an HVAC company, a plumbing business, an electrical contracting firm, or any other service-based trade business, you already know your industry is different. The work is physical. The relationships are local. The business often runs on your reputation, your license, and your crew.
What you may not know is that buyers see your business differently too. A plumbing company and a software company might generate the same revenue, but they do not sell for the same price. The multiples are different, the risks are different, and the documentation buyers ask for is completely different.
This guide breaks down exactly how trade businesses are valued, what drives those numbers up or down, and what you can do right now to understand where you stand.
Why Trade Businesses Are Valued Differently Than Other Industries
Most business valuation content is written for industries where assets are digital, customers are sticky, and the owner is one of many people running the operation. Trade businesses are almost the opposite of that.
In a trade business, the owner is typically the most skilled person in the building. They hold the license. They know the long-term clients. They show up on the job site. When a buyer looks at a trade business, the first question they ask is not how much it earns. The first question is: what happens to those earnings when the owner leaves?
That question shapes everything about how your business gets valued.
Trade businesses are almost always valued using Seller’s Discretionary Earnings, or SDE. SDE is your net profit plus the owner’s salary, benefits, and any personal expenses run through the business. It represents what a full-time owner-operator could expect to earn by running the business themselves. From there, a buyer applies a multiple to that SDE number to arrive at a purchase price.
What Multiples Are HVAC, Plumbing, and Electrical Companies Actually Selling For Right Now
Based on current lower middle market deal activity, most trade businesses in the $500K to $5M SDE range are selling at multiples of 2.5x to 4.5x SDE. HVAC companies with strong recurring maintenance contracts are at the higher end of that range, often reaching 3.5x to 4.5x. Plumbing and electrical contractors without recurring service programs typically trade between 2.5x and 3.5x. Roofing and general contracting sits between 2.0x and 3.0x. Landscaping and lawn care businesses with route-based revenue generally fall between 3.0x and 4.0x.
These are ranges, not guarantees. A business at the low end of its range and one at the high end can have identical revenue and still sell for very different prices. The difference comes down to the specific factors covered below.
It is also worth noting that private equity has become increasingly active in the trades space, particularly in HVAC and plumbing. PE-backed rollups are paying premium multiples for well-organized businesses with recurring revenue. If your business fits that profile, the ceiling may be higher than these ranges suggest.
How Recurring Service Contracts and Route Revenue Change Your Valuation
Of all the factors that move a trade business multiple up, recurring revenue is the most powerful.
A buyer who acquires an HVAC company with 400 active maintenance agreements is buying a revenue stream that shows up every year regardless of how hard the owner works that month. That predictability is worth real money in a valuation.
Contrast that with a company that does primarily project-based or emergency work. Every week starts at zero. There is no backlog, no guaranteed revenue, and no way for a buyer to model future cash flow with confidence. That uncertainty gets priced in as a lower multiple.
If your trade business does not currently have a recurring service program, this is one of the highest-return improvements you can make before a sale. Even a modest base of maintenance contracts can meaningfully shift your multiple.
The Transferability Problem
Here is the issue that kills more trade business valuations than any other: the business does not transfer cleanly.
Transferability means a buyer can step in, operate the business, and retain the customers and revenue without everything falling apart because the original owner left. In many trade businesses, this is a real problem.
If your business license is held by you personally and cannot be transferred, a buyer has a problem. If your top clients have a personal relationship with you and no meaningful relationship with your crew, a buyer has a problem. If you handle all the quoting, scheduling, and customer escalations, a buyer has a serious problem.
None of these issues are necessarily deal-killers, but they all get reflected in the price. A buyer will either discount the multiple to account for transition risk or structure an earnout that ties part of your payment to whether the business retains its revenue after you leave.
The best thing you can do is identify your transferability gaps before a buyer does. Build relationships between your crew and your clients. Document your processes. Get a qualified manager handling day-to-day operations. The more the business can run without you, the more it is worth.
Owner Dependency in Trade Businesses
Owner dependency is related to transferability but slightly different. Transferability is about whether the business can survive the transition. Owner dependency is about how deeply the current owner is embedded in the day-to-day operations.
Buyers assess owner dependency by asking questions like: How many hours a week does the owner work? What would happen if the owner took a 30-day vacation? Does the business have a general manager or lead technician who could step up?
A trade business where the owner is the best technician, the primary salesperson, the estimator, and the person who handles upset customers will get a lower multiple than one where those functions are distributed across a competent team.
If you are planning to sell in the next two to five years, start thinking about this now. Hire people who can handle the functions you currently own. Train your team to handle client relationships. Document your processes so someone else can follow them. Every dollar you spend reducing owner dependency is likely to return several dollars in a higher sale price.
What Buyers Always Ask For
When a serious buyer or their advisor evaluates a trade business, they will ask for a specific set of documents. Most trade business owners are not prepared for this list.
Expect requests for three years of profit and loss statements, three years of tax returns, a customer list with revenue by customer, a list of active service contracts with renewal dates, copies of all business licenses and certifications, an employee roster with roles and compensation, any non-compete agreements with employees, an equipment list with approximate values, and documentation of any pending litigation or regulatory issues.
Most trade business owners have this information somewhere, but it is scattered across QuickBooks, a filing cabinet, and their own memory. Getting this documentation organized before you go to market saves time, reduces friction, and signals to buyers that you run a professional operation.
How to Use a Valuation to Build Toward a Higher Exit Number
If you are not planning to sell immediately, a professional business valuation is still one of the most valuable tools you can have.
A valuation gives you a baseline. It tells you what your business is worth today, why it is worth that amount, and specifically what is holding your multiple down. With that information, you can make targeted improvements over the next one to three years that directly increase your sale price.
For most trade business owners, the highest-leverage improvements are building recurring revenue, reducing owner dependency, cleaning up financial documentation, and addressing customer concentration issues.
The owners who walk away with the best outcomes are almost never the ones who decided to sell and scrambled to get ready. They are the ones who knew their number years in advance and spent that time building toward a better one.
