Michael Kost

Michael Kost, doing business as Fairfield Refrigeration & Cooling Equipment, operates as a service-disabled veteran-owned small business (SDVOSB) sole proprietorship providing HVAC maintenance, repair, installation, and refrigeration equipment services to federal facilities as a prime contractor. The Bronx, New York-based vendor specializes in heating, ventilation, air-conditioning, and mechanical systems work under NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors) and PSC J041, competing predominantly under SDVOSB and small business set-asides across a 58-award federal footprint totaling $13.3 million in combined potential value.

The customer concentration is pronounced and stable. Veterans Integrated Service Network 2 (VA) anchors 53% of awards (31 contracts, $7.7 million) and is the dominant dollar driver; the Department of Transportation Maritime Administration accounts for 34% of awards (20 contracts, $1.2 million) through work at the U.S. Merchant Marine Academy in Kings Point, New York; and the Federal Bureau of Prisons Field Acquisition Office holds a single high-value contract for $3.8 million. The vendor has worked with nine distinct agencies, but the top three capture 98% of combined potential value. Fairfield Refrigeration's work for VA concentrates at the James J. Peters VA Medical Center in Bronx, New York, where it has performed emergency and planned repairs on air handling units, chillers, steam systems, condensers, and fire pumps — representative work includes a $1.4 million Liebert air conditioning maintenance purchase order (FY2026–2031) under total small business set-aside; a $1.2 million definitive contract for laundry ventilation system refurbishment and upgrade at St. Albans VA Medical Center (May 2026); a $779 thousand quarterly preventative maintenance order on 22 cooling units at James J. Peters (FY2025–2030); and a $3.8 million Bureau of Prisons replacement of air handling units at Metropolitan Detention Center Brooklyn (June 2024, small business set-aside). Maritime Administration work spans similar HVAC services at dormitories and facility infrastructure at Kings Point, including exhaust fan replacement, boiler work, and steam-pipe repairs.

Award activity has contracted sharply since 2023. The vendor received 11 awards in both 2022 and 2023, declined to five in 2024, two in 2025, and five in 2026 year-to-date (as of August). Three awards with ultimate completion dates within the next twenty-four months carry $1.8 million in combined potential value and face recompete exposure. The vendor operates as a 100% prime contractor with no subcontractor engagement — all 58 awards are direct prime work. SCI-reported invoicing on federal service contracts above the $150,000 threshold totaled $726 thousand in FY2025 across 1.4 full-time equivalents on prime deliveries; SCI data is sparse and covers only contracts that crossed the reporting threshold, understating the vendor's total federal services revenue. Fairfield Refrigeration competes across SDVOSB sole-source and competitive SDVOSB set-asides as well as total small business set-asides, with no full-and-open awards in the recent footprint, indicating a deliberate posture anchored to its veteran-owned certification and small business size standard of $19 million under applicable NAICS codes.
