Fahnestock was founded in 1946 by E.G. "Ed" Fahnestock, Sr. and his son E.G. "Ted" Fahnestock, Jr. supplying the post-war boom in construction, the company soon became the Wichita area's leading providers of residential and light commercial HVAC. At Fahnestock, we install only the highest-quality equipment and parts — many of them made right here in Wichita. While we are occasionally involved in projects elsewhere in Kansas, most of our work is performed within a 50-mile radius of Wichita.
