The AC Rochat Company was created by Agenor Rochat in 1927, providing refrigeration and HVAC installation/service to the eastern Tennessee region. Among many others, Agenor Rochat employed his younger brother John and in later years after his service during the Korean War, Sidney Guignard.
Forty years later in 1967, John Rochat bought the assets of the company from Agenor; changing the name to Rochat’s HVAC Service.
And several years later in 1978, after working in the HVAC industry most of his adult life; Sidney Guignard acquired the HVAC installation division from his cousin John Rochat and named his new company: Rochat’s Four Seasons Comfort. At that time, John Rochat retained the HVAC service division and they continued to operate both companies from a joint location on Nash Road.
In 1981, Four Seasons Comfort bought their first brand new vehicle – a white 1981 Chevrolet Step van.
In the early 1980s, the company’s focus began to shift from residential to light commercial offices and retail. And around 1987, the HVAC installation division grew substantially to serve the rapidly expanding retail market, installing HVAC systems in shopping malls from Atlanta to the Tri-Cities area.
