Jim Hall built Systems Management & Balancing (SMB) into a quiet powerhouse in a niche most people never think about – but rely on every day. What started in 1967 as a small Des Moines operation grew into a multi-state firm focused on testing, adjusting, and balancing (TAB) HVAC systems to ensure buildings actually perform the way they were designed. Jim shares the bet he made when he acquired the company in 2002, leaning into independence and precision as their differentiator. In an industry where comfort, safety, and efficiency are on the line – especially in hospitals, schools, and complex facilities – SMB has become the “truth-teller,” identifying problems others miss and ensuring systems function as intended.

Joined by consultant Erin Rollenhagen, the conversation shifts to what it takes to evolve and scale a highly specialized business. Erin brings a strategic lens to leadership, growth, and positioning, highlighting the opportunities – and risks – that come with complexity in today’s built environments. Together, they reflect on Jim’s succession plan, the importance of developing talent in a technical field, and why this behind-the-scenes work offers meaningful, high-impact careers. It’s a conversation about legacy, precision, and the kind of Iowa-built business that quietly keeps the world running.
