Who We Are

General Air has deep roots in Greenville that date back to 1959. That was the year that Aleck Clark purchased General Heating and Air Conditioning of Greenville Co, Inc. Until 1992, General Air was a service department within the larger company; however, Mr. Clark decided to pull the service and replacement departments and form a new company called General Air Conditioning Service Corporation to focus on service, maintenance and replacement HVAC in the residential, commercial and light industrial markets of Upstate South Carolina. Robert Clark, Aleck’s son, is now the CEO of General Air and strives to continue the family legacy of expert, quality service.
