Our Team

Our History

Roy Hilton, founder of Hilton Electrical, Automation, & Testing Services, Inc. (HEATSINC), started the company in 2012. No stranger to the industry, Roy has worked in various roles within the electrical testing and commissioning world, bringing with him over 30 years of coveted experience. HEATSINC was born out of his conviction to provide work that is unmatched in quality, uphold the highest of industry standards, and create stability for his employees.

Operations began in the Hilton’s home in Dublin, a city strategically located in the heart of Georgia. Dublin is known for its southern hospitality and charm, and it is an easy drive from the Hartsfield-Jackson Atlanta International Airport. It wasn’t long before we outgrew our home-based office, and in 2014 we moved to a new, 18,000-square-foot facility in East Dublin. Our growth has allowed us to focus on expanding our project management services and an in-house fabrication shop for the design and build of proprietary electrical control panels.

We are a family-owned company with 150+ full-time field employees. As members of the Dublin-Laurens County Chamber of Commerce, we are proud to support our community where our employees live, work, and play. While providing services across the country and the world, we remain family oriented and integrity-focused.
