About Us

At J. F. Ahern Co., we build systems that keep you safe; that maintain cleanliness and sanitation; that regulate temperature. We build systems that serve you. Since 1880, we have performed a full range of mechanical services on projects from several thousand dollars to over 20 million.

We are equally comfortable working for municipalities, institutions, manufacturers, and commercial developers and builders in both private and public sectors. We operate as prime contractor or subcontractor.

One of the leading mechanical and fire protection contractors in the United States, J. F. Ahern Co. is a privately-held company headquartered in Fond du Lac, Wisconsin, with branch offices throughout the upper Midwest.

We employ approximately 1,000 people, consisting primarily of members of the U.A. (the United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States and Canada). We also employ union laborers, millwrights, operating engineers, and sheet metal workers, as well as a complete in-house corporate service team.
