Optimum Energy Co. Announces Acquisition of Hussung Mechanical Contractors and HMC Service Company
Leading mechanical contractor with 60-year history joins Optimum Energy platform
SEATTLE, WA and BATON ROUGE, LA – August 12, 2026 — Optimum Energy Co., a global holistic infrastructure solutions company, today announced the acquisition of Hussung Mechanical Contractors and HMC Service Company, a full-service mechanical infrastructure services firm for healthcare systems, universities, manufacturers, data centers and mission critical facilities across the Mid-South for over 60 years. Hussung will continue operating under its own name as HMC, as part of the Optimum Energy group.
“My grandfather and his brother started this company with a straightforward promise: do quality work, act with integrity, and take care of the customer. Six decades later, that promise is still the reason customers call us and the reason people build careers here. This partnership gives HMC the platform to grow faster and smarter without changing the foundation that made this company worth building in the first place.”
David C. Hussung, CEO, Hussung Mechanical Contractors/HMC Service Company
