The 42-year-old business started out as Bill Fagan Inc. The company eventually changed hands through some of the Fagans’ older sons and became The Fagan Co. in 1981. At the time the company specialized in commercial hvac design-build. The four owners were Bill C. Fagan, Tom Fagan (he has since left the company), Bob Fountain (eventually bought out by Bill Iler), and Ken Karr.
The company operates satellite divisions in Wichita and Fort Scott, KS, and Springfield, MO, employing almost 400 workers. In the first full year (1999) following its acquisition by ComfortSystems USA (Comfort), the company had revenues of $50 million.
