Brothers Mechanical Services LLC

Brothers Mechanical Services LLC, operating as Brothers Mechanical Services under its BMS Division, is a minority-owned, self-certified small disadvantaged business based in Manassas, Virginia, that delivers HVAC maintenance, boiler plant operations, chiller repair and replacement, generator servicing, and related mechanical and facilities infrastructure support to federal agencies exclusively as a prime contractor. The firm is Subcontinent Asian Indian American owned, Department of Transportation certified as a disadvantaged business enterprise, and structured as a limited liability partnership. Brothers Mechanical Services competes predominantly under small business set-asides — particularly Total Small Business designations — though it also wins full-and-open procurements across civilian and defense agencies.

The vendor's customer base is highly concentrated. The Social Security Administration anchors the portfolio with $16.1 million in combined potential value across six awards, followed by Naval Facilities Engineering Command ($10.2 million across six awards) and the Defense Commissary Agency ($8.9 million across fifteen awards). The Department of Veterans Affairs Veterans Integrated Service Network 5, the Marine Corps, the Drug Enforcement Administration, and the National Oceanic and Atmospheric Administration round out the top tier. Together, the top five customers by potential value represent 64% of the vendor's $71.4 million combined potential value.

Brothers Mechanical Services operates three major indefinite delivery vehicles. The Social Security Administration awarded a $15.7 million single-award IDC through August 2025 for boiler plant operations and maintenance at SSA headquarters, with multiple task orders placed annually for chiller repairs, feeder pump servicing, and preventive generator maintenance. In December 2025, Veterans Integrated Service Network 5 awarded a $1.08 million single-award IDIQ through December 2030 for comprehensive boiler preventative maintenance at Loch Raven Medical Center in Baltimore, Maryland, with an initial $277,096 delivery order issued the same day. Naval Sea Systems Command executed a multiple-award Basic Ordering Agreement in December 2024 (effective through November 2029) for mechanical and controls maintenance spanning HVAC, boiler, chiller, generator, electrical, and kitchen equipment services across Navy installations in the Washington, D.C. region and Baltimore. The vendor also places delivery orders under the GSA Multiple Award Schedule, with thirty-one task orders generating $4.8 million combined potential value.

Recent representative work demonstrates the vendor's core footprint. A $620,160 Total Small Business set-aside purchase order from the Department of the Interior Interior Business Center (awarded September 2026, running through 2031) covers preventative maintenance and repair on commercial kitchen equipment at the Stewart Lee Udall Building in Washington, D.C., including monthly inspections, quarterly comprehensive maintenance, grease trap service, hood cleaning, and emergency response. A $1.79 million firm fixed-price purchase order from the Drug Enforcement Administration (awarded April 2026, running one year) addresses chiller replacement at the DEA's Manassas facility. A $1.69 million Total Small Business set-aside definitive contract with the DEA (awarded March 2026 through March 2031) provides HVAC maintenance services at its Merrifield facility. A $370,000 full-and-open purchase order from the National Institute of Standards and Technology (awarded October 2025 through September 2030) covers cooling tower maintenance at the Center for Neutron Research in Gaithersburg, Maryland, encompassing semi-annual and annual maintenance of two structures supporting a nuclear test reactor, with emergency repair capability. Historically, the vendor won a significant $3.99 million 8(a) sole-source definitive contract with NIST in December 2021 for HVAC work across eight laboratories.

Activity has grown substantially. The vendor secured six awards in 2022, thirteen in 2023, seventeen in 2024, twenty-four in 2025, and eight so far in 2026. Eight awards totaling $3.3 million combined potential value face ultimate completion within the next twenty-four months, representing near-term recompete exposure. Service Contract Inventory records, a subset capturing federal service contracts above the $150,000 threshold, show $8.1 million invoiced in FY2023 across roughly 11.1 full-time equivalents, with no SCI-reportable revenue recorded in subsequent fiscal years covered by the source, suggesting a shift toward smaller or goods-based procurements not captured in SCI. On GSA Schedule labor, the vendor offers two rate categories spanning $99 to $119 per hour for HVAC technician roles (junior and senior field technician levels) requiring high school or associate degree credentials with no security clearance mandate.

The vendor operates entirely as a prime contractor — all 174 awards are prime contracts and IDVs with zero subcontract activity recorded in the source data. This posture reflects direct relationships with federal agencies for on-site facilities maintenance rather than a teaming or feeder model. Primary NAICS classification is 238220 (Plumbing, Heating, and Air-Conditioning Contractors), accounting for 110 of 174 awards, with secondary activity in commercial/industrial machinery repair (24 awards) and HVAC equipment manufacturing (9 awards). PSC distribution centers on refrigeration and air-conditioning equipment maintenance (41 awards), plumbing and heating equipment maintenance (21 awards), and inspection services (17 awards), confirming the vendor's specialization in building systems and critical infrastructure support.
