Clarke & Rush Mechanical, Inc.

Clarke & Rush Mechanical, Inc., a self-certified small disadvantaged business headquartered in Sacramento, California, provides HVAC maintenance, repair, and installation services to federal agencies exclusively as a prime contractor under total small business set-asides. The company operates across NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors) with a federal award footprint concentrated on heating, ventilation, and air-conditioning equipment maintenance and repair under PSC categories aligned to facility systems work.

The vendor's customer base is heavily concentrated with the Department of the Interior Bureau of Reclamation, which accounts for 17 of 42 total prime awards and $486 thousand of the combined $612 thousand potential value across the portfolio — representing 79% of recent award volume and 98% of combined potential dollars. The Department of Homeland Security U.S. Coast Guard provides secondary volume (six awards, $105 thousand combined potential value), with the Department of the Air Force, the General Services Administration Public Buildings Service, and the Department of the Navy representing smaller shares. The two customer rankings track tightly, indicating consistent dollar sizing across the active set.

Clarke & Rush Mechanical operates under a single-award blanket purchase agreement with the Bureau of Reclamation (BPA 140R2021A0028) valued at $225 thousand through June 2026, which has generated eight task orders carrying $193 thousand in combined potential value. Recent representative work includes a $105 thousand BPA call order for Folsom HVAC repair services (award September 20, 2022, completion December 31, 2023), a $43 thousand BPA call for Folsom HVAC repair (award May 24, 2024, completion June 29, 2025), and a $3.2 thousand purchase order for repairs to six HVAC units at the Willows Construction Office (award June 26, 2023). All named awards carry total small business set-aside designations with firm fixed-price contracting and performance concentrated at Folsom, California and subordinate Bureau of Reclamation facilities.

Activity has declined significantly — six awards in 2021 falling to one award in both 2023 and 2024, with a single award in 2026. The vendor holds no current subcontract footprint; all 42 awards in the portfolio are prime contracts. The combined dollars obligated ($1 million) exceed the combined potential value ($612 thousand) by 165 percent, indicating invoiced performance against the BPA vehicle exceeds initial ceiling valuations, a signal of sustained task-order volume and reorder performance.
