A total of 39 member contractors nationwide have earned this distinction since the program’s inception in 2008.

MSCA GreenStar was created by MSCA to recognize mechanical service contractors that have developed the skills and expertise necessary to deliver energy-efficient, cost-effective indoor environmental solutions to their customers. MSCA has been recognized by the U.S. Green Building Council (USGBC) for its leadership and stewardship of sustainability practices in the HVACR industry.
