The company Excelcon was originally started in November 1995 with the name Excel Technologies. We serve customers in Contra Costa and Alameda counties servicing all major appliances, both European and American. The experience we have gained in those years has given us the understanding of how to meet the household needs for comfort. In 1999 the company changed its name to Excel Contracting Company, the reason for that was because we started on a new area of services; Heating & Air Conditioning, light plumbing, repairing, designing and installing complete systems. Three years later the state law required more licensing and permits to make businesses more stable and protected, and that's when we became incorporated. We are now expanding our business to offer commercial services.
