Quick answer

Commercial buyers pay most for recurring maintenance and service agreements, not one-off project work. Separate service revenue from construction, document your contracts and technician licenses, and make sure a licensed ACR contractor other than you is on staff. Then run a confidential process with platform buyers and regional mechanical firms at the same time.

Who buys commercial hvac and mechanical businesses in the Valley

  • Commercial HVAC service platforms backed by private equity. They buy contractors with maintenance agreements for schools, hospitals, offices and retail, and often keep the owner on for a period.
  • Commercial refrigeration and foodservice equipment service platforms, which value grocery, restaurant and cold storage customers.
  • Building automation and controls groups that pay for controls technicians and service contracts.
  • Large Texas mechanical contractors expanding into South Texas, mostly for bigger firms.
  • Out-of-market buyers making their first Valley acquisition, who need a licensed local team to serve customers they already have here.

What raises your price

  • Recurring preventive maintenance and inspection contracts with written terms and renewal history.
  • A high share of service and repair revenue compared with bid construction work.
  • Building automation and controls capability.
  • A diversified customer base. An advisor estimates any single customer above 15% of revenue can cost 0.25x to 0.5x EBITDA (CT Acquisitions).
  • Licensed technicians with EPA 608 certification and low turnover.
  • A general manager or operations lead who runs the business day to day.
  • Clean TDLR standing, with licensing that matches the work performed.

What lowers your price

  • Revenue dominated by low-margin bid projects with no recurring base.
  • One school district, hospital or industrial customer making up a large share of revenue.
  • The owner as the only licensed ACR contractor.
  • Open TDLR complaints or licensing that does not match the work. An advisor estimates TDLR issues found in diligence can cost 0.25x to 0.75x (CT Acquisitions).
  • Weak job costing, so buyers cannot see which work actually makes money.

How deals are priced

An advisor's Texas HVAC ranges put companies under $500K of SDE at roughly 2.5x to 4.5x SDE, $500K to $1.5M of EBITDA at about 3.5x to 5.5x, and $1.5M to $5M of EBITDA at about 5x to 7x (CT Acquisitions, a broker estimate covering HVAC broadly). The same source notes that a commercial firm with one customer above 30% of revenue trades closer to the low end. Small deals vary widely.

Licensing and closing risks

  • A person may not engage in air conditioning and refrigeration contracting in Texas without a TDLR license (Texas Occupations Code 1302.251).
  • An ACR contracting company must employ full time, in each permanent office, a license holder whose license is assigned to that company (Texas Occupations Code 1302.252). If that is you, the buyer needs a replacement before closing.
  • If you also do plumbing or electrical work, those trades are licensed separately: plumbing by the Texas State Board of Plumbing Examiners and electrical by TDLR, each tied to named license holders.
  • Public sector and institutional service contracts often have assignment or change of control clauses and bonding requirements. Review them early.
  • Warranty obligations and open projects should be scheduled in the purchase agreement so you are not carrying risk after closing.

Sale-readiness scorecard

Answer eight yes or no questions. Your score and the items to fix first update as you go. Nothing you click is saved or sent anywhere.

  1. Is a meaningful share of revenue from written maintenance agreements?

    Recurring service is what commercial buyers pay for.

  2. Is no single customer more than about 15% of revenue?

    Concentration lowers the multiple.

  3. Is a licensed ACR contractor other than you assigned to the company?

    Texas law requires one in each permanent office.

  4. Are TDLR licenses and EPA 608 certifications current for all technicians?

    Licensing gaps cut value.

  5. Can you show margins by service versus project work?

    Buyers value the two very differently.

  6. Could an operations manager run the business for 90 days without you?

    Owner dependence adds earnouts.

  7. Have you reviewed contracts for assignment and bonding terms?

    These can delay closing.

  8. Are your books on accrual and CPA reviewed?

    Verified numbers support price.

Your preparation checklist

  1. 24 months out: split revenue into maintenance agreements, service and repair, and project work.
  2. Put every maintenance customer on a written agreement with clear renewal terms.
  3. Build a customer concentration report and grow smaller accounts if one customer dominates.
  4. Make sure a licensed ACR contractor other than you is on staff and assigned to the company.
  5. Confirm TDLR licenses and EPA 608 certifications for every technician.
  6. Move to accrual accounting and get a CPA review or audit of the last two to three years.
  7. Set up job costing so service and project margins are visible.
  8. Promote or hire an operations manager who can run dispatch and estimating.
  9. Review contracts for assignment clauses, bonding and warranty obligations.
  10. 6 to 12 months out: build a confidential buyer list across commercial platforms, refrigeration and controls buyers and regional mechanical firms, then go to market.

How long a sale takes

As a planning assumption, expect about 6 to 12 months from going to market to closing. Contract assignments, license transitions and work in progress schedules usually take longer in commercial deals than in residential ones.

The Rio Grande Valley angle

Valley schools, hospitals, produce cold storage and border logistics facilities depend on cooling that cannot fail for long. A private equity backed commercial HVAC buyer has already completed a Valley acquisition, which shows platforms will pay for the right local contractor. Hidalgo County alone grew to about 921,549 residents in 2025 (U.S. Census Bureau estimates via FRED).

FAQ

Frequently asked questions

Who buys commercial HVAC companies in South Texas?
Commercial HVAC service platforms backed by private equity, refrigeration and controls specialists, large Texas mechanical contractors and out-of-market buyers making a first Valley acquisition. At least one platform has already bought in the Valley, which shows the market is on their radar.
Why are maintenance contracts worth more than project revenue?
Maintenance agreements repeat every year and lead to repair work, so buyers can predict them. Bid projects end when the job ends and margins swing. Buyers price recurring service much higher, so growing your service base before a sale can raise your price.
What if I am the only licensed contractor?
Texas requires an ACR company to employ a licensed contractor full time in each permanent office. If that is you, the buyer either needs you to stay through a transition or needs a replacement. Hiring or developing a second licensed contractor before you sell protects your price.
How are commercial HVAC companies valued?
Mostly on adjusted EBITDA. An advisor's Texas ranges put $500K to $1.5M of EBITDA at about 3.5x to 5.5x and $1.5M to $5M at about 5x to 7x. Recurring service, customer spread and management depth move you within the range.
Can a buyer use an SBA loan to buy my business?
Often, and SBA loans are common for smaller deals, but the rules changed. Since March 1, 2026, SBA 7(a) and 504 loans require every direct and indirect owner of the borrower to be a U.S. citizen or U.S. national living in the U.S., so green card holders can no longer use SBA financing (Coleman Report on the SBA notice). Platforms usually pay cash, but smaller commercial deals with individual buyers often depend on SBA loans. Delta's guide on the SBA citizenship rule and your buyer explains what this means for your buyer pool.
What does Delta Brokers charge, and are you my lawyer or CPA?
Delta Brokers is a veteran-owned sell-side M&A firm in McAllen. Our fee is tied to the sale of the business only, and we never earn real estate commissions. We are not a law firm or a CPA firm, so you will still want your own attorney and tax advisor. Our job is to prepare the business, find and qualify buyers, create competition, and manage the process to closing.
