Robert J Hill

Robert J Hill, doing business as Hill Refrigeration West, is a woman-owned small business based in White, South Dakota, that provides HVAC and refrigeration equipment installation, repair, and replacement services to federal agencies as a prime contractor on 83% of recent awards. Hill Refrigeration West operates as a sole proprietorship and competes entirely under the Total Small Business set-aside across its federal footprint.

Hill Refrigeration West's capability portfolio centers on commercial refrigeration system installation and replacement, emergency HVAC component repair, and associated demolition and facility preparation work. Representative prime work includes a $670,999 purchase order from USDA Agricultural Research Service Plains Area (awarded September 2023) to replace six walk-in chambers at the Brookings, South Dakota research facility, completed August 2024; a $44,945 Total Small Business purchase order from USDA-ARS Plains Area (awarded April 2026) to upgrade a seed storage cooler with a new commercial-grade refrigeration system capable of maintaining precise environmental conditions; and an $18,225 purchase order from the Bureau of Indian Education (awarded August 2026) for emergency replacement of a dormitory compressor at Flandreau, South Dakota. The source notes that Hill Refrigeration West has executed all prior awards as prime contractor without subcontractors, demonstrating independent capacity to manage complex facility maintenance projects, and meets South Dakota HVAC licensing requirements with a minimum of five years' experience. The vendor's sub footprint is minimal — one subcontract with Mill Creek Firelake JV LLC for walk-in chamber demolition and installation work, awarded December 2025.

Customer concentration is extreme. USDA Agricultural Research Service Plains Area accounts for 100% of the combined potential value across the active award set (five awards, $757 thousand), with the Bureau of Indian Education representing one award worth $18 thousand. The two rankings are identical; there is no tension between volume and dollars. Activity has been sparse and episodic — two awards in 2023, two in 2025, and two in 2026 — across a three-year window. Combined potential value reported in the source is $775 thousand, but combined dollars obligated stands at $1.5 million (196% of potential value), indicating substantial invoicing against ceiling estimates on prior awards. Hill Refrigeration West operates under one parent vehicle, an Indefinite Delivery Contract (12805B24D0003), with one task order. The vendor's footprint is heavily weighted toward NAICS 235110 (Plumbing, Heating, and Air-Conditioning Contractors) and PSC code 4452 (Maint/Repair/Rebuild of Equipment — Refrigeration, Air Conditioning, and Air Circulating Equipment).
