The Brandt Legacy


When Sonny Brandt started a Dallas-based air conditioning company in 1952, he saw the opportunity created by a growing population and hot Texas summers. His strategic expansions over the years grew a small local business into a thriving leader in the construction, design, and service industries.


More than six decades later, Brandt is bigger and better than ever. From our days as Brandt Engineering, Brandt Mechanical, and Brandt Service in the 70s and 80s, the firm has grown to a suite of companies, offering full-service solutions as a single provider to large and complex construction and asset management projects.


Brandt added an electrical division in the early 2000s. The Brandt Companies were created under the leadership of Barry Moore and Mark Zilbermann in an ever-expanding quest to provide our clients with on-time, in-budget construction service, complete commissioning assistance, and long-term facilities maintenance. We expanded into HVAC service and full-service MEP operations. In the 2010s, Brandt established the industrial division focusing directly on the unique needs of industrial clients.  Expanding on the growing industrial market, Brandt acquired Hilbig Services in 2018.

Brandt Today

In 2022, Brandt was acquired by Southland Industries. This acquisition aligned with Brandt’s goal to become a truly national company that can better serve our customers, increase our industry influence towards more collaborative delivery approaches, and create additional opportunities for our employees.


With offices in all of the major Texas cities and over $550 million in annual revenues, Brandt has established itself as the largest mechanical, electrical, and plumbing contractor in the state. With in-house capabilities that start with build/design, construction and commissioning and end up in service, Brandt works every day to provide the solutions and service to meet your ever-changing needs.

With over 70 years of industry expertise, Brandt harnesses the combined power of more than 2,700 highly trained employees – industry leading craftsmen, licensed engineers, trained technicians and technology.

Our Core Values

The Brandt Companies’ core values are the foundation on which we have built our business. They guide how we conduct ourselves daily and keep us on course in an ever-changing world. They underlie our work, our interactions and our strategic decisions


Care is at the core of everything we do. Our reliable, consistent customer service is the cornerstone of our work. However, our dedication to care isn’t only related to our customers. Our employees are the foundation of our company, and we protect one another at every turn. Safety is our top priority on the job, and we work hard to help those who trust us with their careers to find plenty of time for life outside the workplace.


We do whatever it takes to live up to our commitments. Over the course of a long and complex project, that means fostering a culture of adaptability and creativity. We understand that construction and working in fully operational facilities can be hard and demanding. We understand that it takes resilience and drive to meet the changing demands of our clients, and we are focused on successfully making it to the finish line.


To respond to ever changing conditions, businesses must be able to adapt quickly and easily. Using leading-edge technologies, we proactively manage our work to help us identify problems early and fix them fast. We can’t always predict what will happen, but we are always ready for the challenges that come our way.


Our relationships with customers, vendors and employees are based on respect and honesty. It is our unwavering policy to do what we say we will do, when we say we will do it. From design to construction to service, integrity is what we demand of ourselves and our team members.
