Mitsubishi Electric U.S. Inc. Cooling & Heating Division has launched the Diamond Commercial Contractor Program, a network of contractors that can represent City Multi products in design-build, retrofit and build-to-suit projects.

“For the last couple of years, we’ve worked on proactive ways to recognize the efforts of commercial mechanical contractors who have demonstrated a commitment to the growth of our commercial HVAC products and services,” said Mike Hampton, senior manager of strategic programs at Mitsubishi Electric. “Through the Diamond Commercial Contractor program, building owners and facility managers gain access to industry-best guidance and expertise in addition to our high-performing (variable refrigerant flow) systems.”

Prospective contractors must be nominated by Mitsubishi Electric distributors or manufacturer representatives and then approved by program officials. Membership benefits include priority listing on, priority access to a technical service phone support line, extended warranty plans and more.
