Our Story

During the 1940’s John W. Jennings and Jack Dill, Sr., believed that technological advances were creating the need for a new type of contractor in the South— a contractor specializing in the installation of heating, air conditioning, and process piping systems in homes, businesses, and industrial plants throughout the Southeast.

John Jennings and Jack Dill, Sr., opened Super Supply Company in 1947 and after a decade of rapid growth, recognized the demand for qualified Mechanical Contractors in the growing commercial and industrial markets of the Southeast. And with a name change to Jennings-Dill, Inc. Mechanical Contractors, we expanded our services and market areas.

Jack Dill, Sr.

Jack Dill, Jr., joined the company in 1965, and brought with him uncompromising integrity, demand for the highest level of quality, and the ability to develop and maintain relationships. As a Clemson graduate in Mechanical Engineering and a registered P.E., Jack’s professional knowledge and experience provided guidance that grew the company and earned Jennings-Dill an outstanding reputation in the industry. Under Jack Dill, Jr.’s leadership as President, Jennings-Dill expanded to specialize in air conditioning/heating installation, plumbing, piping, metal fabrication, and millwright work, and employed over 175 employees.

With over 50 years of experience in the industry, Jack Dill, Jr., continues to provide leadership as CEO and Chairman of the Board and continues to advise, support, and contribute to the engineering efforts of the corporation.

Bruce Henson was named President in 2016 after 25 years of experience within the company as Project Manager, Director of Business Administration, Vice President, and General Manager. Bruce has a BS degree in Business Administration from Winthrop University and is licensed in HVAC and Plumbing in multiple states. As a third-generation leader of the family business, Bruce is committed to maintaining the company’s 70 plus year legacy of integrity, safety, and quality.

Tyler Henson joined Jennings-Dill, Inc. in 2020 as Engineering Manager, becoming the fourth-generation addition to the family business.

From there, Tyler was accepted to enter the Edison Engineering Development Program at GE where he participated in a rigorous engineering training program while earning his Master of Science in Mechanical Engineering from Georgia Tech in 2017. Following the completion of the Edison Program, Tyler continued to work as a Gas Turbine Design Lead Engineer at GE and became a registered P.E. in 2019.  Currently focusing on engineering excellence, Tyler will continue to ensure the company’s high standard for quality.
