Precision Mechanical Services, LLC

Precision Mechanical Services, LLC, a Philadelphia-based small business, provides HVAC, mechanical system repair, and facility maintenance services to federal agencies as a pure prime contractor operating across GSA Multiple Award Schedule and small-business-set-aside indefinite delivery vehicles. The company is a Subchapter S corporation competing entirely on full-and-open and small-business-set-aside grounds — 83% of recent awards carry total small business set-aside designations, anchored by a $1.54 million single-award indefinite delivery contract with Naval Sea Systems Command for cooling water tower system preventative and corrective maintenance through June 2029.

Precision Mechanical's capability portfolio centers on HVAC preventative maintenance, emergency repairs, cooling tower and chiller system servicing, and facility mechanical contracting for federal property operations. The company's primary NAICS codes are 238220 (Plumbing, Heating, and Air-Conditioning Contractors) and 562910 (Facilities Support Services), with GSA labor rates spanning service mechanics for controls, chillers, cooling towers, boilers, steam systems, and refrigeration equipment, all at high-school-education entry level requiring five years of journeyman experience and no security clearances. Representative recent contracts include a $405,472 total small business delivery order from Naval Sea Systems Command for pump motor replacement at the Philadelphia Naval Business Center (August 2025 award), a $99,673 small-business-set-aside purchase order from the National Park Service Northeast Region for IT chiller service at the William Penn Annex East facility in Philadelphia extending through April 2029 (May 2024 award), a $80,384 total small business contract from NPS Northeast Region for residential HVAC maintenance at Valley Forge National Historical Park through August 2029 (August 2025 award), and a $210,557 delivery order from the Department of Agriculture Agricultural Research Service for HVAC system repairs and reheat coil replacement at the Glenside facility (April 2023 award).

Naval Sea Systems Command dominates customer concentration by both award count and dollars — 11 awards carrying $2.8 million in combined potential value. The National Park Service Northeast Region follows with 8 awards and $347 thousand combined potential value, while the Department of Agriculture Agricultural Research Service holds 4 awards and $434 thousand combined potential value across two named regional variants. The Department of Veterans Affairs Veterans Health Administration appears as a single high-value outlier with $2.4 million combined potential value, and the GSA Federal Acquisition Service carries a $1 million award. The top five customer agencies account for 83% of recent awards but only 97% of combined potential value — NAVSEA's volume translates to modest per-order dollar value, while the Veterans Affairs award and GSA vehicle anchors distort the ranking toward dollars.

Precision Mechanical operates through two parent vehicles: the GSA Multiple Award Schedule, which has issued 8 delivery orders carrying $589 thousand in combined potential value, and the Naval Sea Systems Command single-award Indefinite Delivery Contract N6449824D4011, which has generated 6 delivery orders worth $339 thousand combined. A $100,000 multiple-award Blanket Purchase Agreement with the Pennsylvania National Guard for dining facility equipment repair at Fort Indiantown Gap runs through April 2028. Activity has grown from four awards in 2023 to eight in 2024 and six in 2025, though one award posted in March 2026. Only one award — the $47 thousand National Park Service Pacific West Region heating, ventilation, and air conditioning preventative and on-call services contract — faces ultimate completion within the next twenty-four months, creating minimal recompete exposure in the near term. The company competes exclusively as a prime, with no subcontract footprint in the source data.

Precision Mechanical Services is an Industrial / commercial mechanical company that provides service to major pharmaceutical, industrial, educational and institutional organizations in the Philadelphia region.
