THD Contracting Service LLC

THD Contracting Service LLC MR. Division, a minority-owned, Black American-owned small business based in Philadelphia, Pennsylvania, operates as a prime contractor delivering refrigeration, HVAC, and mechanical infrastructure installation and repair services to federal agencies exclusively under total small business set-asides. The vendor is a for-profit limited liability company that competes entirely within the small-business reserve and has no subcontract footprint.

The vendor's capability portfolio centers on walk-in cooler and freezer installation, refrigeration system replacement, HVAC equipment upgrades, and associated mechanical infrastructure work for federal research, forestry, and storage facilities. Representative work includes a $158,301 cold room renovation for the National Oceanic and Atmospheric Administration (awarded March 3, 2023, with completion date September 30, 2023), a $113,945 forest-wide tree cooler repair and renovation project across the Boise National Forest for the Department of Agriculture Forest Service Intermountain Region (awarded July 29, 2024, with completion by October 8, 2024), and a $89,265 prefabricated cold storage room installation at Pennsylvania State University's Agricultural Research Service facility (awarded April 21, 2026, with completion targeted for September 1, 2026). More recent work includes a $34,950 refrigeration system replacement for the Chequamegon-Nicolet National Forest in Wisconsin (awarded September 30, 2025) and a $51,304 HVAC system replacement on the Kootenai National Forest in Montana (awarded July 8, 2025).

Customer concentration spans ten distinct federal agencies, with the Department of Agriculture accounting for the largest award share across its Forest Service regional offices and Agricultural Marketing Service Cotton and Tobacco Program (six awards, $393 thousand combined value). The Department of Commerce NOAA anchors the largest single award at $158,301. Activity has grown incrementally — one award in 2018, two in 2023, three in 2024, and four in 2025 — with combined potential value across all eleven recent awards totaling $740 thousand, representing 100% obligated dollars. Only one award, the USDA Agricultural Research Service cold storage installation, faces completion in the next twenty-four months, carrying $89 thousand in potential value and therefore limited recompete exposure in that window. The vendor's work is classified consistently across NAICS codes 236220 (Commercial and Institutional Building Construction), 238220 (Plumbing, Heating, and Air-Conditioning Contractors), and allied mechanical repair codes, with PSC codes driven by refrigeration equipment and HVAC installation and maintenance activities.
