How to sell an HVAC or plumbing business in Texas

Selling an HVAC or plumbing business in Texas turns on three things a buyer can verify: how much of your revenue is recurring service agreement revenue, whether the company runs without you, and whether the license the work is performed under can legally follow the company to a new owner. The third one is specific to the trades, it is not fixable at closing, and most sellers have never checked it.

Residential home services is one of the most actively bought sectors in Texas right now. Private equity backed platforms are assembling multi trade companies across Dallas, Fort Worth, Houston, and Austin, and they are buying independent HVAC, plumbing, and electrical contractors to do it. If you own one, you have probably already gotten the letters and the LinkedIn messages.

That interest is real, and it is also uneven. The same buyers who will pay a full price for a well built residential replacement and service business will pay much less for a company of identical size whose revenue comes from homebuilders, whose owner sells every job, and whose service agreements exist mostly on paper. This guide covers what separates those two outcomes, and what an owner can actually change in the eighteen months before going to market.

What buyers pay for in an HVAC or plumbing business

Buyers of residential home services companies pay for recurring revenue, replacement work, and a management bench, in that order. They pay much less for new construction volume, even profitable new construction volume, and they pay nothing extra for revenue that depends on the owner personally closing the sale.

The reason is repeatability. A homeowner who replaces a system today is not a customer again for a decade. Residential HVAC equipment has a useful life in the range of twelve to eighteen years, per the 2026 Home Services M&A Multiples Report published by CT Acquisitions, so a replacement customer with no maintenance relationship is effectively a one time transaction. A customer on a maintenance agreement is a scheduled visit twice a year, a diagnostic touchpoint, and a first call when the system finally fails.

New construction revenue is the clearest discount. The same CT Acquisitions report describes homebuilder dependent revenue as discounted 1.5 to 3 times versus replacement revenue, and puts a small owner sold operator that is mostly new construction at the bottom of its range while a larger business with heavy service agreement density and a general manager sits at the top. Treat those specific numbers as one advisory firm's own benchmark rather than as measured market data, because the report does not disclose a sample size and the firm earns transaction fees. The direction of the finding, though, matches what buyers say out loud: builder work is cyclical, margin thin, concentrated in a handful of accounts, and it disappears in a housing slowdown that also happens to be when the buyer would be holding the business.

Margin follows the same pattern. Emergency and demand service typically carries higher gross margin than planned replacement, which is why a buyer will look at your revenue mix before your revenue total. Two contractors doing $6 million each are not the same asset if one is 70 percent residential replacement and service and the other is 70 percent tract homes.

Your Texas contractor license does not transfer with the business

An air conditioning and refrigeration contractor license issued by the Texas Department of Licensing and Regulation belongs to a person, not to a company, and TDLR states plainly in its published summary of the program that these licenses are not transferable. The same is true on the plumbing side. The Texas State Board of Plumbing Examiners issues the Responsible Master Plumber designation to an individual licensed Master Plumber, and its published rules state that a Responsible Master Plumber may act in that role for only one company at a time.

A Responsible Master Plumber, usually called an RMP, is the individual license holder legally responsible for supervising and managing the plumbing work performed under contracts secured with that license, including pulling permits, requesting inspections, and confirming that everyone doing the work is licensed or registered. TSBPE requires that person to hold a current Texas Master Plumber license, be in good standing, and carry at least $300,000 of commercial general liability insurance.

Here is why that matters at closing. If you are the license holder, the buyer is not acquiring your license along with your trucks and your customer list. The buyer is acquiring a company that must have a qualified individual in that seat on day one. TDLR states that an air conditioning and refrigeration contracting company must employ a licensed ACR contractor at each permanent location, and that a company without one at the time a contract for services is signed cannot collect a fee or enforce that contract. That is not a paperwork inconvenience. That is a company that cannot legally bill for the work it just sold.

The License Continuity Test

Run these three questions on your own company before a buyer runs them on you. Any answer that is not immediate and documented is a readiness item, not a diligence item.

• Whose name is actually on the license the company operates under? Pull the license record and read the name. If it is yours, and you plan to be gone ninety days after closing, the buyer has a problem that gets priced. If it is a long tenured employee, the buyer's next question is what keeps that employee here, which turns a licensing question into a retention question.
• Can that person legally hold the seat for the buyer's entity on closing day? An asset sale usually means a new legal entity, which means the qualifying individual has to be employed by and designated for that new entity, with insurance in place, before the entity can contract for work. The RMP restriction to one company at a time matters here, because a license holder who is still designated for your old entity cannot simply also cover the new one.
• What happens to work sold in the gap? Ask your attorney what the exposure is on contracts signed during any window where the entity does not have the required license holder in place. TDLR's own summary answers part of that question for air conditioning work, and the answer is not favorable to the company.

The clean version of this is a second qualifying license holder on staff who is not the owner, employed and designated well before the business goes to market. There were 19,163 air conditioning and refrigeration contractor licenses active in Texas in fiscal year 2025 out of 60,552 total ACR licenses, per TDLR, and the contractor license requires roughly 48 months of qualifying practical experience plus a state exam. You cannot manufacture a second license holder in the sixty days between LOI and closing. Eighteen months out, you can.

Licensing is one instance of a broader problem, which is that permits, registrations, and agreements do not automatically follow a sale. The same logic applies to your lease, your fleet financing, and your large commercial accounts. A fuller version of the mapping exercise is in which contracts a buyer actually inherits.

What a service agreement is worth, and how a buyer tests whether yours are real

A residential service agreement, sold in most markets as a membership, comfort club, or maintenance plan, is a recurring contract under which a homeowner pays a monthly or annual fee for scheduled maintenance visits and usually receives priority scheduling and a discount on repairs. It is the single most valuable structural feature a residential trades business can have, because it converts one time customers into a renewable base with a known renewal rate.

Buyers benchmark agreement penetration as a share of revenue. The CT Acquisitions 2026 report puts under 10 percent in its discount zone, 15 to 30 percent as market, and 40 percent or more as its premium zone, and reports typical annual renewal rates of 70 to 90 percent for well run programs. Again, that is an advisory firm's internal benchmark rather than an audited dataset, so use it as a direction of travel. The direction is unmistakable: agreement density moves price more than revenue growth does.

What surprises sellers is how hard buyers test the agreements. A buyer's diligence team will ask for the agreement count, the churn rate month by month, the average revenue per agreement, the visit completion rate, and the deferred revenue balance for visits paid for but not yet delivered. Agreements that are sold but not serviced, agreements that auto renew but that customers do not recognize, and agreements with no completed visit in the trailing year get discounted heavily or excluded from the recurring revenue figure entirely.

If your field service platform holds the agreement data and your accounting system does not know about it, that gap is your problem to close before market, not the buyer's problem to discover during it. Prepaid maintenance is a liability the buyer is taking on, and it shows up in the working capital conversation. The broader case for why buyers pay differently for repeatable revenue is in how recurring revenue changes a business valuation.

The two labor numbers a buyer runs before anything else

Revenue per technician and twelve month technician retention are the first two operating metrics a home services buyer calculates, because both are proxies for whether the business can be scaled by the buyer at all. A company that cannot keep technicians cannot absorb the growth capital that justifies the price.

The CT Acquisitions report puts market revenue per technician for HVAC at roughly $180,000 to $220,000 with a premium tier above $250,000, and market twelve month technician retention at 70 to 80 percent with a premium tier at 85 percent or better. It also describes buyers applying explicit price reductions where a business has been holding revenue together with aggressive overtime or chronic understaffing, on the theory that the buyer inherits the cost of rebuilding the crew. Those thresholds come from one firm's benchmark, but every buyer in this sector runs some version of both calculations, and yours will be compared to a number they carry in their head.

The reason this hits harder in the trades than in most industries is the licensing ladder underneath it. A technician is not a fungible hire. In air conditioning work, Texas registers or certifies technicians through TDLR and requires them to work under the supervision of a licensed contractor, which means the bench you have is the bench the buyer gets, and rebuilding it takes years rather than weeks. Retention data is worth pulling before a buyer asks, and if the twelve month number is bad, eighteen months of fixing it is worth more than any presentation about culture.

Owner dependence is the same problem one level up. If you personally sell the large replacement jobs, hold the builder or property manager relationships, or dispatch when it gets busy, the buyer is looking at a job rather than an asset, and prices it that way. The playbook for unwinding that is in reducing owner dependence before a sale, and the money side of holding onto the people who matter is in key employee retention when selling a business.

Trucks and equipment do not get added on top of the price

The fleet, the tooling, and the shop inventory are almost never added on top of an earnings multiple in a home services sale, because those assets are what produce the earnings the multiple is already applied to. Owners routinely arrive at a first meeting with a valuation built as earnings times a multiple, plus the appraised value of eighteen trucks. That is double counting, and a buyer will say so.

What the fleet does affect is the deduction. A buyer prices deferred replacement. If the average truck age means six vehicles need replacing in year one, that spend is real, it is quantifiable, and it comes off the price or into a holdback. The same logic applies to a shop full of obsolete recovery equipment or a fleet with no maintenance records.

Inventory is its own conversation. Home services businesses often carry meaningful equipment and parts stock, and whether that inventory is counted inside the working capital target or bought separately is set by the purchase agreement rather than by a general rule. What the answer depends on is how the letter of intent defines the working capital components, whether inventory is valued at cost or at some adjusted figure, and how obsolete stock is treated. Ask the buyer in writing which of those apply before you sign anything, rather than assuming the treatment you would prefer.

Who buys HVAC and plumbing companies in Texas

Three buyer pools compete for residential trades companies in Texas, and which one fits you is mostly a function of your earnings size. Knowing which pool you are in before you talk to anyone is what keeps you from selling a platform sized business at add on pricing.

Individual and search fund buyers, usually SBA financed, are the market for smaller owner operated companies. The buyer is a person, the lender makes the real credit decision, and the process is slower because a credit committee has to underwrite your cash flow and your books have to tie to your filed returns.

Private equity backed multi trade platforms are the most active buyers in the DFW market at the moment. A platform headquartered in Dallas can pay more for a Fort Worth business than for an identical business in another state, because the closer company tucks into an existing dispatch, call center, and procurement footprint. That is not sentiment, it is arithmetic on the buyer's side, and it is the single best reason for a North Texas owner to make sure the local platforms are all looking at the file at the same time.

Strategic buyers, meaning larger regional contractors expanding their trade mix or their service area, are the third pool. A plumbing company is worth more to an HVAC platform that wants plumbing in the same trucks than it is to another plumber, because the strategic buyer is pricing what your customer base is worth inside their overhead rather than inside yours.

The differences between how these three price, how fast they close, and what changes after closing are laid out in SBA buyer versus private equity versus strategic buyer. The practical point for a home services owner is that these pools value the exact same company differently, which is why running a process that reaches all three is worth more than negotiating harder with the one that found you first. If your work is more commercial and project based than residential and recurring, the pricing logic changes again, and how buyers price a construction business is the better starting point.

The 18 month prep list for a home services exit

Eighteen months is the realistic runway for changing the things that move price in this sector, because the three biggest levers, licensing depth, agreement density, and technician retention, all measure in years rather than quarters.

• Get a second qualifying license holder on staff and designated. Not promised, not in progress. Employed, licensed, insured where required, and on the record.
• Grow service agreement penetration and clean up the base. Cancel or re service the agreements nobody has visited. A smaller honest number survives diligence; a larger fictional one gets thrown out along with your credibility on everything else.
• Reconcile the field service platform to the accounting system every month. Agreement counts, deferred revenue for unperformed visits, and job level margin should agree between the two systems before a buyer ever compares them.
• Shift the revenue mix toward residential replacement and service. If builder work is more than a quarter of revenue, know that number, be ready to explain the margin on it, and understand it will be valued differently than the rest.
• Fix the technician retention number, then document it. Twelve month retention, revenue per technician, and average tenure, tracked monthly, with a pay band comparison you can defend.
• Take yourself out of sales and dispatch. A general manager who runs the day to day and a sales process that does not require you is worth more than any single year of revenue growth.
• Get on accrual books with a real monthly close. Buyers underwrite twelve to thirty six months of monthly financials, and a business that closes its books forty days late looks like a business that does not know its own margin.

None of that list is exotic. All of it takes time, which is the only thing an owner cannot buy back once a buyer is already at the table. The businesses that get competitive offers in this sector are not the ones with the best story. They are the ones where every claim in the story can be pulled up on a screen while the buyer watches.

Selling an HVAC or plumbing company in Dallas or anywhere across North Texas means selling into a buyer pool that has looked at dozens of files like yours this year and knows exactly which numbers separate them.
