From piping-only roots to full-service offering, Midstate Mechanical continues to evolve

Midstate Mechanical LLC (Midstate) has spent nearly four decades building a reputation as a dependable, forward-thinking mechanical, electrical and plumbing (MEP) contractor. From modest beginnings as a piping-only operation in 1986, the Arizona-based business has evolved into a full-service provider without losing sight of the adaptability and relationships that fueled its early growth.

Originally focused on HVAC piping, Midstate quickly adapted to market shifts, and by 1990, the company expanded into sheet metal, where it found itself competing directly with former partners. Plumbing followed in the late 1990s, following requests from clients. “Many of our customers began asking for us to deliver plumbing and increasingly sought bundled services,” opens company President, Bob Sowa, explaining how it became an MEP contractor and continued to evolve through the 2000s. Midstate’s launch of an energy services division following the 2008 financial crisis was a move that also proved pivotal. “We lost around $20 million worth of work in a week,” Bob recalls. “I asked our founder, Dave Jones, what we were going to do, and he simply said, ‘I don’t know right now, but we’ll figure it out.’” That confidence translated into action. By creating self-generated projects through energy savings, Midstate not only weathered the downturn but emerged stronger than many competitors. “Dave’s ability to pivot was pretty instrumental in keeping Midstate at the level we’re at now,” Bob states.

Today, Midstate primarily operates in public sector markets, including municipalities and education, while maintaining flexibility to follow trusted clients into new sectors. This approach has taken the company into diverse project types – from advanced manufacturing to warehouses – while maintaining a disciplined focus on where it can deliver the most value. Equally important is how Midstate secures its work. Rather than relying heavily on hard-bid projects, the company prioritizes negotiated contracts and early involvement, as Bob emphasizes: “It’s one thing to be a known contractor, but to be sought after because of our abilities is how we want to differentiate ourselves. Hire us and we’ll take care of it – that’s essentially the goal.”

Embracing innovation

Another major turning point came in 2023, when Midstate was acquired by Kassel Mechanical, a private equity-backed group. While acquisitions can often disrupt operations, Bob describes the transition as a net positive – particularly in terms of resources and collaboration. Now part of a much larger organization, Midstate has an employee network of around 1900, and this scale has unlocked new opportunities for knowledge sharing and operational improvement. Employees also have access to enhanced benefits, including improved healthcare and retirement plans – both key advantages in a competitive labor market.

Midstate has long embraced innovation, but its integration of technology has accelerated under Kassel’s influence. The company was an early adopter of Building Information Modeling (BIM) and now leverages advanced tools such as 3D scanning and multi-trade prefabrication. “BIM is a standard process for us,” states Bob. “It’s becoming more of a daily tool at every opportunity.” The company is also developing AI-driven solutions to streamline estimating, document management and change tracking. “With some of the AI tools that we’ve built today, we know within minutes whether there’s any impact. The speed of information to the field is critical.”

Among Midstate’s upcoming work is the largest high school ever built in Arizona – an ambitious project with an uncompromising timeline. Due to start construction in July, the building is scheduled for use just 12 months later. “Delivering a project of this scale under such constraints would be nearly impossible without our technical capabilities,” highlights Bob. “Without the BIM coordination or prefabrication, that project would never be successful.” Midstate has worked on similar projects with the same customer previously, earning repeat work through its reputation for reliability and execution under pressure.

Expanding capabilities

As the business grows, so does its focus on workforce development. Like many contractors, Midstate faces ongoing labor shortages, particularly in skilled trades. “There just aren’t enough construction workers in the State of Arizona to cover the amount of work,” reveals Bob. In response, the company is investing heavily in training and launching a formal apprenticeship program through Kassel. This initiative aims to bridge the experience gap created by an influx of younger, less experienced workers. “We need to process work differently to better situate their success out in the field,” he explains, underlining empowerment and collaboration. “We always strive to give the team the flexibility to make decisions, and coach them as we go along.”

Midstate’s next phase of growth will center on expanding its prefabrication capabilities, scaling its electrical division and increasing revenue by up to 50 percent over the next five years. A new, larger facility – featuring a prefab shop four times the size of its current space – will play a central role in that strategy. At the same time, the company is pursuing measured geographic and service expansion, both organically and through acquisition. Ultimately, Midstate’s ambition is clear: to become the contractor of choice for complex MEP projects. “Growing revenue is fantastic,” concludes Bob. “However, growing revenue and remaining profitable is more important, as is bringing value to our customers.”
