About Entech Engineering

Thomas Engineering, Inc. was organized in September of 1973 by Wade G. Thomas to design and observe the installation of heating, ventilating and air conditioning systems, plumbing systems, sprinkler systems and other associated mechanical systems.  These systems were for commercial, educational, institutional, governmental and industrial buildings.  We have since provided engineering services on over five thousand projects.

In November 1984, Thomas Engineering, Inc. merged with Tune, Billings, an electrical engineering firm.  Tune, Billings was organized in 1978 by Paul Billings and Nick Tune.

The result of the merger between Thomas Engineering, Inc. and Tune, Billings is Entech Engineering, Inc.

The philosophy of Entech Engineering is to provide complete mechanical and electrical engineering services with personnel having technical ability and practical experience in the field.  Continuing education is emphasized, with personnel encouraged to attend seminars, manufacturer sponsored schools and in-house training sessions.

The firm, in keeping with the urgent need to conserve energy, strives constantly to design systems that operate at the greatest possible efficiency for the smallest possible cost.
