Fosselman Refrigeration, Heating & Air, Inc.

Fosselman Refrigeration, Heating & Air, Inc., a Montana-based self-certified small disadvantaged business and limited liability company, delivers HVAC system installation, replacement, and maintenance services to federal agencies exclusively as a prime contractor under total small business set-asides. The vendor operates from Plains, Montana and competes entirely within the small business reserve, with all five recent awards designated as total small business set-asides.

Fosselman's capability footprint centers on refrigeration and HVAC systems for federal research, operational, and administrative facilities. Work spans HVAC system replacement at tree coolers maintaining precise temperature control for forest service seedling storage, controlled environmental chamber conversion for research facilities, HVAC and roofing replacement at power administration installations, and maintenance of refrigeration systems at wildlife service sites. Representative work includes a $213 thousand definitive contract awarded July 2026 by the Department of Energy Western Area Power Administration for HVAC replacement and TPO roofing at its Casper facility (firm fixed price, completion November 2026); a $68 thousand small business purchase order from the USDA Forest Service Region 1 (Northern Region) in September 2025 for HVAC system replacement at the Ninemile Remount Depot near Huson, Montana, serving tree cooler operations (extended through May 2026); a $63 thousand USDA Forest Service purchase order for replacement of outdated HVAC systems at two tree coolers in the Idaho Panhandle National Forest (completion March 2027); and a $23 thousand Forest Service definitive contract for converting an existing chainsaw testing room into a controlled environmental chamber at the Missoula Technology and Development Center (October 2026–February 2027).

Customer concentration is distributed across four distinct federal agencies. The Department of Energy Western Area Power Administration anchors the dollar value with one $213 thousand award; the USDA Forest Service Region 1 (Northern Region) holds two awards totaling $132 thousand; the Department of the Interior Fish and Wildlife Service Region 8 and the USDA Technology and Development Center each account for one award ($73 thousand and $23 thousand respectively). Activity has grown from one award in 2025 to four in 2026, with four awards (combined potential value $372 thousand) reaching ultimate completion within the next twenty-four months and therefore subject to recompete. Fosselman operates no subcontract footprint; all work is prime-direct to federal agencies.
