About S & D Mechanical Services, Inc.
S & D Mechanical Services, Inc., a Native American-owned, minority-controlled small disadvantaged business based in Grand Blanc, Michigan, operates as a prime contractor providing HVAC system repair, replacement, and facility mechanical infrastructure services to defense and homeland security agencies under 8(a) sole source set-asides. The company holds SBA 8(a) Program certification through June 13, 2027, and competes exclusively under 8(a) and total small business set-aside vehicles; all sixteen awards in the source are set-asides, with thirteen designated 8(a) sole source.
S & D Mechanical's customer footprint is heavily concentrated in Michigan Air National Guard facilities. The Department of the Air Force Air National Guard accounts for 56% of awards (nine contracts, $1.4 million combined potential value), with the Department of Homeland Security Customs and Border Protection representing 25% of awards (four contracts, $784 thousand combined potential value). The Air Force and Defense Finance and Accounting Service round out a four-agency customer set. Both the award-count and potential-value rankings are identical, indicating tight alignment between contract volume and dollar concentration.
Representative work includes a $344,232 definitive contract (September 2025, CBP) to replace the HVAC system at Building 1515 of Selfridge Air National Guard Base through September 2026; a $324,674 definitive contract (September 2025, CBP) to upgrade the existing heating system at Selfridge Air National Guard Base through December 2025; a $298,956 definitive contract (October 2023, Air Force) to repair the HVAC system and replace boilers and 40-ton DX units in Building 17 at Selfridge; and a $248,388 definitive contract (November 2025, Air National Guard) for HVAC repair and dehumidification work in Building 170 at an Air National Guard facility in Harrison Township, Michigan, through June 2026. A $29,571 purchase order to install an automatic transfer switch at a CBP facility (July 2026) represents the most recent award.
S & D Mechanical's capability portfolio is dominated by NAICS 541611 (Plumbing, Heating, and Air-Conditioning Contractors), which covers ten of sixteen awards. The company also performs work under NAICS 332912 (Measuring, Dispensing, and Other Pumping Equipment Manufacturing) and specialty trade contracting for facility modifications and repairs. Recent activity shows two to four awards annually since 2021, with combined obligated dollars at $2.6 million across all sixteen contracts. Two awards with a combined potential value of $374 thousand face completion within the next twenty-four months and represent recompete exposure. The company has no subcontract footprint and does not appear on any government-wide or agency-wide vehicles; all work flows through direct sole-source or small business set-aside awards from customer agencies.
