L&H Airco, a building automation, temperature controls, and lighting controls contractor headquartered in Rocklin, California, has been acquired by Service Logic. Service Logic describes itself as the largest privately held network of HVAC and mechanical services companies in the United States and Canada. The transaction strengthens Service Logic’s controls business and adds density in the Western United States. L&H will continue to operate under its own brand and leadership team. Financial terms were not disclosed.
L&H Airco was established in 1968 and operates from Rocklin with a second office in Fresno. The business is an energy management systems contractor rather than a mechanical contractor — its work runs to system integration, temperature and lighting controls, and energy monitoring, delivered as unified building management solutions. It represents Alerton and Distech temperature controls and Blue Ridge Technologies lighting controls, and its project history spans healthcare, government, military, K–12 and higher education, hospitality, and industrial facilities across California. The company has been led for the past decade by Eric Crise, John Harris, and Jake Garcia.
Crise framed the decision around what the acquirer’s structure would leave intact, saying Service Logic’s “decentralized model preserves the culture and legacy we’ve built over the last decade.”
The platform: 155 locations, 61 companies, one deliberately loose structure
Service Logic is headquartered in Charlotte, North Carolina and has been in commercial HVAC for more than 70 years. It reports 155 locations across the United States and Canada, 61 operating businesses, more than 5,000 service technicians, and roughly a billion square feet of buildings under service. Its work covers preventative maintenance, emergency service, equipment replacement and retrofit, and building automation and energy solutions for commercial, industrial, and institutional customers.
What distinguishes the platform is less the location count than the operating structure behind it. Service Logic has completed more than 110 acquisitions and runs them as a federation rather than a single integrated company: acquired businesses keep their names, their leadership, and day-to-day operational control, and the corporate function supplies training, peer networks, purchasing, and capital rather than a centralized brand or command structure. The company is explicit that it has no revenue or headcount threshold for acquisitions and that its acquisitions team is entirely in-house.
That structure is unusual at this scale. Most platforms that pass a hundred acquisitions have started consolidating brands, standardizing systems, and centralizing back-office functions, because that is where the modeled synergies live. Service Logic has largely declined to, and the trade-off is visible in both directions: it gives up the cost savings of true integration and gets, in exchange, a model that is easier to sell to owners who do not want to be absorbed, and an acquisition pipeline that has stayed open for decades.
Why controls is its own category
It would be easy to file this alongside the mechanical contractor deals that dominate commercial HVAC M&A, but building automation is a structurally different business and tends to be underwritten differently.
The work is engineering-led rather than installation-led, with a meaningful software and systems-integration component, and it is organized around manufacturer lines that take years to earn and maintain. More importantly, the controls layer is where the switching costs live. A mechanical contractor that installs a chiller has delivered a piece of equipment that anyone qualified can subsequently service. A controls contractor that integrates a campus-wide building management system has embedded itself in how the facility runs — the sequences, the graphics, the alarm logic, the energy reporting. Displacing that incumbent means re-integrating the building, which facility owners are reluctant to fund without cause. The result is an installed base that generates durable service, upgrade, and optimization revenue over long horizons.
L&H’s end markets sharpen the point further. Healthcare, government, military, and education facilities carry long procurement cycles, credentialing and compliance requirements, and institutional buyers who change vendors slowly. Those characteristics make the customer base hard to win and correspondingly hard to take away — which is most of what an acquirer is paying for.
What it means
Commercial HVAC and mechanical services have drawn steady acquisition interest for years, and within that, building automation and controls has quietly become one of the more sought-after segments. The reasons are not complicated: recurring service tied to an installed base, real technical barriers to entry, institutional customers that do not churn, and a supplier base that is still largely made up of independent regional contractors.
For owners of controls, building automation, and commercial mechanical businesses, the practical takeaway is that this end of the market is being actively pursued, and by acquirers whose structures differ considerably — some centralizing, some federating, some strategic, some financially sponsored. What that means for any particular company depends on the business and on what its owners actually want out of a transaction.
Wondering where your business sits?
Acquirer interest in commercial HVAC, mechanical services, and building automation has been steady and well capitalized, and most owners have never had a clear read on what their company is worth or which buyers would genuinely be interested. If you’d like an honest assessment of where you stand — valuation, likely buyer interest, and what your options really are — we’re glad to talk. No pitch, no pressure.
