Carson Brothers was founded in 1976 by Greg and Newell Carson to serve the heating, air conditioning, and refrigeration service needs of Northwestern Montana. After 30 years of service to the Flathead Valley, Greg and Newell sold Carson Brothers to Comfort Systems USA in August 1999. Newell retired from the company in 2001. Today, Greg is semi-retired but still a valued member of the team, lending his many years of knowledge, and his outstanding project manager skills to the Carson Brothers organization. Comfort Systems USA provided growth in capital and the ability to better train and develop personnel in the highly technical market.
