Thermosystems, a Member of Daikin Group, Names Mike Murray as President

CHICAGO - Aug. 17, 2022

Thermosystems LLC, a commercial heating, ventilation and air-conditioning (HVAC) manufacturers’ representative serving Chicago, northwest Indiana, and central and southern Illinois, today announced it has appointed Mike Murray as President. Murray, who has been with the firm for more than 10 years as a leading sales engineer, is replacing John Dolan, one of the company’s co-founders, who is retiring after 22 years of service.

“This is an exciting time to lead Thermosystems,” Murray said. “In 2019, Daikin Applied invested in the firm, which helped advance our sales and service capabilities. We also just had a record year in all three of our divisions — Applied Equipment Sales, Building Systems Solutions and Service. Thanks to John’s leadership, and the hard work and accomplishments of the entire organization, we have a solid foundation for years of additional growth.”

As President, Murray is responsible for setting and implementing the company’s strategic vision. His leadership team includes Vice President of Sales Paul Pasternock, another Thermosystems co-founder; Pasternock will continue to direct the Applied Equipment Sales division. In addition, Vice President of Operations Ryan Kelly will oversee the Building Systems Solutions division and manage interdepartmental operations.

Tracy Dorman and Nina Campos will continue to lead the Service division and accounting group, respectively. Together, the leadership team has more than 75 years of experience with Thermosystems and 150 years of experience in the HVAC industry.

“We’ve seen tremendous growth over the past 22 years,” said outgoing President Dolan. “With Mike and the rest of the executive team, Thermosystems is positioned for continued success.”

Murray earned a bachelor’s degree in industrial engineering from Purdue University, and an MBA in corporate finance and real estate from New York University’s Stern School of Business.
