Andy Heilmann
Andrew Heilmann’s journey with MSC began when he was a college student at Rensselaer Polytechnic Institute, during which he’d spent his summers and winter breaks working as a field assistant. At a young age, Heilmann formed a close bond with Harry Hartigan, MSC company founder. Hartigan was a neighbor and a family friend. Early on, Hartigan had recognized Heilmann’s mechanical aptitude and interest in the field of HVAC, and he helped Heilmann nurture those passions. After graduating college in 2013, Andrew joined MSC full-time as a lead project manager, overseeing installations while contributing in-house and field engineering.
Heilmann then took on operations responsibilities in 2017. In 2019, he passed the Professional Engineering exam, becoming a licensed P.E. in the state of New Jersey. In 2024, Harry Hartigan passed the leadership of MSC over to Heilmann, his “protégé,” who he saw to be an embodiment of MSC’s core values.
“Growing up next door to Harry Hartigan, MSC’s founder, was a formative experience for me,” Heilmann said. “Harry had a full machine shop at his house, and as a curious kid interested in all things mechanical, I was always eager to help him with projects. He helped me develop the technical problem-solving skills that have been invaluable in my career. Now he’s entrusted me to lead the organization he built, and I’m grateful for every lesson he taught me along the way.”
Under Heilmann’s leadership, MSC operates under the belief of “ONE TEAM,” fostering a culture of collaboration. This means that every employee, from the top engineers to apprentices, is valued equally and encouraged to contribute their expertise.
MSC works to ensure its service technicians and engineers are fluent in the latest industry advances, technical training, diagnostic tools, and industry certifications. Heilmann actively participates in planning, preparation, and teaching these training sessions, sharing his vast knowledge and ensuring MSC stays at the cutting edge of the industry. Heilmann also recognizes the importance of not only educating the technical staff but educating the salespeople, marketers, and schedulers in the basics of HVAC.
“I want to provide my technicians with the highest level of training and resources so they are equipped to solve highly complex HVAC issues in critical facilities; deliver a customer experience where customers know they can depend on us to do whatever it takes to solve their problems efficiently and effectively; stay on the cutting edge of information and technology, enhancing our ability to serve our customers; proactively address emerging industry trends and guide our customers through the compliance, equipment implications, and future preparedness process; and consistently live our company’s core values and continually build our reputation as expert problem solvers.”
