In Memoriam – Jimmy Hays, Chairman Emeritus

In 1950, Jimmy Hays joined his father, Charles G. Hays, after graduating from Georgia Tech with a degree in Mechanical Engineering. At that time, the family business was still Hays Heating and Plumbing Company. Jimmy eventually became president and expanded the business into air conditioning, the foundation for where Hays Service is today. Jimmy ran the business for over 40 years, and got to see his son and grandson join Hays Service as the company continued to expand.
