About Midwestern Mechanical, Inc.
Midwestern Mechanical, Inc., doing business as Copper Cottage, is a for-profit Subchapter S Corporation based in Sioux Falls, South Dakota that provides HVAC, plumbing, and mechanical maintenance and repair services to federal agencies as a prime contractor, with minimal subcontract exposure. The vendor operates in full-and-open competition with no set-aside designation across its recent federal footprint.
Midwestern Mechanical's customer base concentrates heavily on Veterans Affairs and Indian Health Service programs. The Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 23 accounts for 7 awards totaling $380 thousand in combined potential value, while the Department of Health and Human Services Indian Health Service holds 6 awards worth $269 thousand. These two customers together represent 13 of 17 total awards (76%) and $649 thousand of $847 thousand in combined potential value. The Department of Agriculture Forest Service Job Corps, the Department of the Interior Bureau of Indian Affairs Great Plains Region, and the Department of the Interior National Park Service Midwest Region round out the active set with smaller, episodic work.
The vendor's capability portfolio reflects straightforward mechanical contracting. Primary NAICS concentration sits in Plumbing, Heating, and Air-Conditioning Contractors (12 awards), with secondary exposure in Commercial and Institutional Building Construction. Recent representative work includes a $133 thousand firm fixed-price purchase order from the Forest Service Job Corps awarded in December 2025 to replace failed HVAC components in the Boxelder Kitchen and Dining facility in Nemo, South Dakota (completion April 30, 2026), and an $18 thousand purchase order from the National Park Service Midwest Region in May 2024 for mechanical services in Rapid City, South Dakota. The vendor holds one subcontract as a mechanical performer under the University of Dayton on a Sustainment and Combat Readiness Capabilities installation support effort awarded in February 2025.
Activity remains sparse and irregular—one to two awards per year across the five-year lookback, with combined potential value of $847 thousand across seventeen total prime and sub awards since 2009. The vendor competes in full-and-open federal procurement without set-aside or parent-vehicle positioning.
