Thermosystems, LLC

Thermosystems, LLC, a for-profit partnership subsidiary of Daikin Applied Americas Inc., provides chiller rental, installation, maintenance, refrigeration equipment, and HVAC repair services to federal agencies as a prime contractor operating under full-and-open competition with no set-aside designations. The vendor is based in Elmhurst, Illinois and operates under parent Daikin Applied, a foreign-owned corporate entity headquartered in Minneapolis, Minnesota. Thermosystems' federal footprint centers on equipment manufacturing and facilities services work, with primary NAICS categories in air-conditioning and warm air heating equipment manufacturing and plumbing, heating, and air-conditioning contracting.

Thermosystems' customer base is concentrated across federal facility maintenance networks. The Department of Veterans Affairs accounts for the largest share of awards by count (6 of 16 awards, roughly 38%), split between Veterans Integrated Service Network 12 (5 awards, $199 thousand combined potential value) and the National Acquisition Center (1 award, $652 thousand). However, the ranking by potential value shifts: the Department of Agriculture Agricultural Research Service Field Research Implementation and Information Delivery Midwest Area leads with a single $757 thousand award for chiller rental and installation to a VA facility in Peoria, Illinois. The Department of the Navy Naval Facilities Engineering Command (3 awards, $83 thousand), the Department of the Air Force Air National Guard (2 awards, $12 thousand), and the Department of the Army Installation Management Command Southeast Region (1 award, $59 thousand) round out the top five by dollars. These five customers cover 96% of combined potential value. Representative work includes a $651.8 thousand purchase order from the VA National Acquisition Center (awarded April 24, 2022, running through May 1, 2028) for chiller maintenance and repair of RTUs 9 and 10 in Hines, Illinois; a $27.8 thousand emergency chiller repair order from VA VISN 23 (July 2025); and a $98.3 thousand refrigerant cylinder supply order from VA VISN 12 (August 2023).

Activity has remained sparse and episodic — 16 awards across twenty-two years, with an annual average of less than one award in the past five years (2020: 2 awards; 2022: 1; 2023: 2; 2025: 1; 2026: 1). Two awards totaling $1.4 million carry ultimate completion dates inside the next twenty-four months, creating a modest recompete exposure window. Combined potential value across all awards stands at $1.8 million, with $1.7 million obligated (95% realization rate). Thermosystems operates exclusively as a prime contractor — no subcontract activity appears in the source.
