AT Klemens was founded as a sheet metal shop in 1928. From this heating, ventilating, and air conditioning beginning, we have grown and expanded through the years. The addition of roofing, service, plumbing, and electrical departments has made AT Klemens a multi-service company. Our ability to perform as a prime contractor or as a one-source subcontractor, responsible for the coordination of several crafts, has been a substantial benefit to our customers.
We provide residential and commercial design, sales, and installation and our service personnel are available to properly maintain and repair all systems.
AT Klemens has successfully completed design / build projects as well as plan and specification jobs throughout Montana and several other Western states. We remain competitive through experience and team effort, take pride in our work, and maintain high standards of quality and service in all phases of our operation.
