Sergents Mechanical Systems Inc.

Sergents Mechanical Systems Inc., doing business as Sergent Construction Services, is a Service-Disabled Veteran-Owned Small Business and SBA-certified HUBZone firm headquartered in Santa Paula, California, that operates exclusively as a prime contractor across federal construction and mechanical systems work, holding a portfolio of nine active IDVs and MATOCs spanning construction, HVAC systems, and facility infrastructure services. The vendor competes predominantly under SDVOSB and HUBZone set-asides, which characterize most of its recent prime awards; Sergents Mechanical Systems' SBA certifications—SDVOSB and HUBZone—expire October 27, 2026.

Sergents Mechanical Systems delivers commercial and institutional building construction, HVAC system replacement and installation, mechanical systems upgrades, and facilities repair and alteration services across federal agencies. Representative work includes a $17.9 million SDVOSB-set-aside definitive contract with the Department of Veterans Affairs (VISN 16) for roof and HVAC replacement at Building 9 of the Alexandria VA Health Care System in Pineville, Louisiana (awarded July 2025, completion February 2028); a $3.6 million SDVOSB sole-source contract with the Federal Aviation Administration for chiller replacement at the Houston Air Route Traffic Control Center (awarded September 2025, completion June 2026); a $10.5 million emergency department remodel at VA Central California Healthcare System in Fresno under VISN 21 (awarded March 2023, completion October 2026); and a $4.4 million HUBZone-set-aside contract with the FAA Aeronautical Center for air handler refurbishment at Albuquerque ZAB ARTCC (awarded January 2025, completion May 2026). The vendor's NAICS footprint is dominated by 236220 (Commercial and Institutional Building Construction, 132 awards) and 238220 (Plumbing, Heating, and Air-Conditioning Contractors, 35 awards).

Customer concentration is split between federal customer base by award count and by dollar value. By award count, the Department of the Navy leads with 194 awards, followed by the Department of Homeland Security US Coast Guard (46 awards, $332.2 million combined potential value), the Department of the Army (29 awards), and VISN 21 at the Department of Veterans Affairs (21 awards, $149.6 million combined potential value)—together accounting for 63% of recent awards. By combined potential value, the Federal Aviation Administration dominates with 10 awards carrying $6.01 billion in potential value, followed by VISN 22 at VA ($736.8 million), VISN 19 at VA ($505.4 million), NASA Armstrong Flight Research Center ($459.9 million), and Naval Facilities Engineering Command ($398 million). This divergence reflects Sergents Mechanical Systems' placement on multiple high-ceiling FAA BOAs awarded in 2023 as single-award vehicles, which carry $999,999,999 ceilings each but have generated relatively modest task order volume to date.

Sergents Mechanical Systems holds nine active parent vehicles. The largest by potential value are seven FAA Basic Ordering Agreements for Design/Build and Bid/Build construction services at Air Traffic Control facilities: five multiple-award BOAs (Medium Central Service Area, Medium Western Service Area, Medium Eastern Service Area, Small Western Service Area, and Small Central Service Area) and two single-award BOAs (Small WSA and Small CSA), all awarded February–July 2023 with $999,999,999 ceilings running through February–July 2033. The Coast Guard RMACC 2019 indefinite delivery vehicle carries 19 task orders worth $14.4 million combined potential value. VA VISN 22 holds a $600 million SDVOSB-set-aside multiple-award MATOC running through June 24, 2029 (awarded June 25, 2024), and VA VISN 19 holds a $500 million Design Build MATOC running through May 24, 2027 (awarded June 1, 2024). Naval Facilities Engineering Command awarded a $200 million Total Small Business multiple-award contract for HVAC system projects (NAVFAC Southwest, April 2025 through April 2027) and a $99 million SDVOSB-set-aside contract for general construction in the Yuma and El Centro areas (September 2023 through September 2028). NASA Armstrong awarded a $450 million Partial Small Business set-aside multiple-award construction contract (June 2026 through June 2031), and the Department of Interior Fish and Wildlife Service awarded a $250 million Total Small Business MATOC for alteration, repair, and construction services (January 2022 through December 2026).

Activity has remained steady in recent years (11 awards in 2022, 17 in 2023, 13 in 2024, 12 in 2025, and 4 in the first half of 2026) without sharp growth or decline. Nine awards reach ultimate completion within the next twenty-four months, carrying combined potential value of $34.9 million and presenting recompete risk in that window. Sergents Mechanical Systems operates as a 100% prime contractor with no subcontractor activity in its recent award portfolio—all 483 awards are prime awards, and the vendor does not appear as a named sub on federal contracts in the source data.

SCI-reported federal services invoicing shows $52.6 million across FY2022 through FY2024 (FY2022: $15.1 million across 20.9 FTEs; FY2023: $17.8 million across 23.4 FTEs; FY2024: $19.8 million across 16.8 FTEs). On federal services contracts captured in SCI, median government-paid rates run around $466.85 per hour, with senior labor pricing reaching $2,532 per hour; entry rates sit near $192 per hour. Across SCI-reportable prime contracts, Sergents Mechanical Systems self-performs all labor with zero subcontractor-hours share, reflecting its build-to-order field operations model for construction and facility maintenance work.
