Since 1975
The story of Evergreen starts with a man named Dick Lord. Dick had his own refrigeration company in the 1960’s. His two young and ambitious grandsons, Dave and Roger Patton, joined him there as apprentices.
In 1970, Roger and Dave decided to start their own businesses. One had a residential HVAC shop while the other specialized in commercial refrigeration. Then, in 1975, the brothers combined their businesses and Evergreen Refrigeration was born. Throughout the decades, Evergreen has been known as a company built on innovation, customer service, merit principles, and family values.
Rodger continues to play a role in Evergreen's management and business operations. Dave passed away in 2011 after a battle with cancer leaving an indelible impact on the company’s core principles and culture. This impact has become a large part of Evergreen's core values as his children continue his vision through the coming generations. Matt Patton, Dave's eldest son, is currently the company's General Manager, overseeing the entire operation. Adam Patton, Dave's second son, is the Commercial Construction Manager, overseeing field operations for the company. Doug Patton, Dave's third son, is the Sales and Engineering manager, overseeing system sales, engineering and design. With three generations of knowledge passed to the current management team, Evergreen has continued with both eyes on the future to ensure that the company flourishes as a leader in the Design Buil HVAC industry in the Seattle and Puget Sound areas.
