Peace of Mind Under Your Roof Since 1950



Don Wyckoff Sr. enlists in the Navy to repair war ships during World War II. He was only 19 years-old and had recently married 15 year-old Mary Rose Davis. After three years of service, Don returns home from the South Pacific and goes to work for Universal Heating in Des Moines.




Don Wyckoff, Jr. – future owner of Wyckoff Heating & Cooling, is born on January 1, 1946. Don Sr. and Mary Rose go on to have six more children – Pam, Ron, Doak, Kyle, Kay, and Tobie.




Don Sr. begins work for Clark-Peterson Company, a large heating and cooling company in Des Moines. He works with an old Navy buddy, Kenny Horn.




“I quit my job to start a business,” Don says to Mary Rose. It is May 1950, and Don had a plan to start his own business with partner Kenny Horn. Together, they formed Wyckoff-Horn Heating and Cooling Company. Their first customer was Bob Stout of Community Builders. “We worked seven years without taking a day off,” Don Sr. later said.




After 10 years in business together, Don and Kenny part ways, and Don decides to start his own business, Don Wyckoff Heating. Don moves his family to the country outside of Carlisle and starts doing business out of his basement, eventually hiring his first employee after six months.




By this time the business had grown so much that in 1973 Don Wyckoff Heating moved into the old grocery store on School Street in Carlisle.




Don moves the business to a two-story building where a swimming pool company used to be.




Don and Mary Rose’s five sons – Don Jr., Ron, Doak, Kyle and Tobie – take over the business when Don Sr. retires.




Don Wyckoff Heating purchases the Clark-Peterson Company where Don had worked in the late 1940s. This acquisition doubled the number of employees to 50.



The business moves from Carlisle to larger quarters at 1201 SE Diehl Avenue in Des Moines. As the business expands into new areas, the Wyckoffs started doing business as Wyckoff Industries.



Wyckoff is asked to participate in an American-style housing project in Kofu, Japan, Des Moines’ sister city. This led to several more projects over the years.




Don Jr.’s son, Andy Wyckoff, and Pam’s son, Job Cooper, become third generation owners of Wyckoff Industries taking their place alongside Don Jr., Ron, Doak, Kyle and Tobie. There are also several other Wyckoffs in the family business performing other key duties.




With a new location on Highway 5 in Carlisle, Wyckoff Industries continues to serve central Iowa under the leadership of third-generation owners Andy Wyckoff and Job Cooper. With strong family commitment from the third and fourth generations and employee loyalty, Wyckoff will be a trusted name in the Des Moines area for years to come.
