History

Volunteer Mechanical was established in 1992 by Dennis and Kimberly Wood. It originally began as a small service company backed by Dennis’ 14 years of service e

xperience. As the company grew, a sheetmetal shop was added in the garage. The growing business then became incorporated in 1996. One year later Volunteer Mechanical Inc. had out grown its previous space and moved to its present location at 527 Callahan Drive where it continues to grow. Currently Volunteer Mechanical has a full sheetmetal fabrication shop, large parts warehouse, full line of service and construction vehicles, welding machines, power tools, lifts and other necessary items to provide professional service and installation of heating, ventilating and air conditioning systems.
