Morrison, Inc. Proudly Serves These Counties in the Mid-Ohio Valley:


A Legacy of HVAC Excellence Since 1961

Army veteran Harley Morrison started a HVAC company in a small shop on Greene Street in Marietta, Ohio. He offered heating, air conditioning, and appliance repair for homeowners in the area. In 1961, he partnered with fellow Army veteran Edwin “Jack” Haas. They incorporated to form Morrison, Inc. Along with this, they expanded and constructed a sales and service complex at 410 Colegate Drive in Marietta, our current location. Our company’s first motto, “Service Comes First Here,” reflected our customer-driven dedication.

A Second Generation Building on the Foundation

In 1979, our company welcomed its second generation, with the addition of Harley’s son, Ken. And in 1983, Jack’s son, David, joined Morrison, Inc. Ken, after working his way through the ranks, became president in 1986. David also held many positions in our company until succeeding Ken as president in 2017. Continuing our family tradition is Ken’s stepson, Chase, who currently serves as our vice president for development of our commercial business.
