About the company
Midwestern Mechanical, Inc., doing business as Copper Cottage, a for-profit Subchapter S Corporation headquartered in Sioux Falls, South Dakota, provides HVAC maintenance, heating and cooling system repair, and mechanical building systems services to federal agencies primarily as a prime contractor (94% of recent awards). The vendor operates in the plumbing, heating, and air-conditioning contracting space (NAICS 238220) and does not compete under SBA set-asides; all recent awards carry full-and-open, firm fixed price purchase order designations.
Midwestern Mechanical's customer base concentrates heavily with the Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 23 and the Department of Health and Human Services Indian Health Service, which together account for 89% of awards and 98% of combined potential value. VISN 23 has generated seven awards totaling $380 thousand in combined potential value; IHS has placed six awards worth $269 thousand. The Department of Agriculture Forest Service Job Corps, the Department of the Interior Bureau of Indian Affairs Great Plains Region, and the National Park Service Midwest Region round out the active customer set with one award each. The vendor's geographic footprint tracks to the Upper Midwest and Northern Plains — Sioux Falls, South Dakota serves as the administrative base, with performance occurring in Nemo, South Dakota (Forest Service Job Corps), Flandreau, South Dakota (Bureau of Indian Education), and Rapid City, South Dakota (NPS).
Recent representative work includes a $133 thousand purchase order from Forest Service Job Corps (December 2025) to replace failed HVAC components in the Boxelder Kitchen and Dining facility due to an emergency moratorium exception, a $15.8 thousand purchase order from the Bureau of Indian Education (August 2026) to replace a heating pump in Building 121 at Flandreau with completion targeted for December 2026, and a $18.7 thousand purchase order from the NPS Midwest Region (May 2024) for unspecified mechanical services in Rapid City. The vendor carries one subcontract award as a sub to the University of Dayton on a Sustainment and Combat Readiness Capabilities (SABR-C) project at Ellsworth Booth Installation (February 2025). Activity remains modest and sporadic — one or two awards per year across the past five years — with a combined potential value of $863 thousand across eighteen total awards since 2009. One award ($16 thousand) faces ultimate completion within the next twenty-four months.
