KSW TruckJim Kenney, Syl Severson and Bob Weller had a mutual desire to form their own company after working together at Urban Heating in Owatonna. The initials in their last names formed the now familiar KSW that has grown into a major force in home and commercial comfort over the past four plus decades. Originally, KSW started out as a roofing and sheet metal company. Then later went into the servicing furnaces when roofing jobs became scarce. Eventually Jim Kenney became the sole owner and has continued the KSW tradition as a family owned business.
