Quality from day one
In 1946, John Cahoy began employment with Milne & Chase. He purchased part of the company
with William Mueller in 1952, and company became known as Mueller & Cahoy.
Our organization began in 1938 as a company known as Milne & Chase. The company erected windmills and installed
reciprocating well pumps commonly known as "stroke pumps" that were powered by the windmills.
A family tradition
The advance of rural electric cooperatives brought
electric motors to rural wells, and allowed Mueller & Cahoy to begin installing pressurized systems for such wells, as well as line shaft turbines for municipalities in northeast Iowa.
In 1979, Duane Cahoy purchased William Mueller's share of the business and the company became known
as Cahoy, Inc. While the name has changed, our philosophy on business has remained the same: personal attention, dedication
to quality, and ever-expanding knowledge and service.
