​RMMS History

Rocky Mountain Mechanical Systems was founded in 1983 (as Rocky Mountain Refrigeration, Heating and Air Conditioning) by Jeff and Peggy Erdman.

Bruce and Patty Byrd purchased the company and relocated from Denver to Grand County, CO. They continued to design, install and maintain refrigeration, HVAC and mechanical systems and commercial appliances in Grand and Summit Counties.

The Byrds formed a partnership with Mark and Karen Dawson and renamed the company Rocky Mountain Mechanical Systems, Inc.

RMMS offices relocated to Denver, CO.

Rocky Mountain Mechanical Systems, Inc. celebrated 30 years of superior customer service and solutions as the premier industrial refrigeration company in the Rocky Mountain region.

Rocky Mountain Mechanical Systems joined the Comfort Systems USA team in January, 2015.  The decision to join Comfort Systems was fueled by a desire to keep pace with the needs of our most successful customers. Colorado has seen great economic growth, particularly in the food industry, and with the strength gained by joining a national company, RMMS will be able to continue serving the growing needs of our customers.
