About the company
Macdonald-Miller Facility Solutions LLC, a for-profit limited liability company based in SeaTac, Washington, provides HVAC maintenance, repair, and installation services to federal agencies as a prime contractor (86% of recent awards) and as a subcontractor on Navy vessel modernization programs. The company competes in the open market with no set-aside designation across its prime footprint.
Macdonald-Miller's customer concentration is heavily weighted toward Navy operations and maritime maintenance. The top five funding agencies by award count account for 68% of recent awards, led by the Federal Emergency Management Agency Region 10 (28 awards, $73 thousand combined potential value) and the Department of the Navy Naval Sea Systems Command (23 awards, $2.1 million combined potential value), followed by NOAA, the Department of Justice Federal Bureau of Investigation Seattle Field Office, and the Environmental Protection Agency. By dollar value, the Navy dominates: Naval Sea Systems Command anchors 87% of combined potential value across the top five customers ($2.1 million of $3.8 million total), with the Department of the Army ($494 thousand) and NOAA ($308 thousand) providing secondary depth. Macdonald-Miller's NAICS footprint is concentrated in plumbing, heating, and air-conditioning contracting (51 awards) and ship-building and repairing (20 awards), with PSC coding emphasizing HVAC maintenance and refrigeration equipment repair.
Representative prime work includes a $436,350 Navy definitive contract awarded July 2022 for AC GROOM services on USS Rushmore (LSD-47) in Japan; a $181,468 Department of Justice Bureau of Prisons purchase order from September 2023 for CAT generator radiator removal and replacement at the Federal Detention Center SeaTac; a $54,986 NOAA single-source purchase order from July 2026 for emergency chiller compressor repair at the Manchester Research Station (justified under FAR 6.302-2 for unusual and compelling urgency to preserve sablefish broodstock); and recurring NOAA chiller repair and parts-replacement orders ranging from $3,725 to $45,295. Recent activity has accelerated, growing from two awards in 2022 to sixteen in 2025, with only one award (combined potential value $4 thousand) reaching completion inside the next twenty-four months. In its subcontractor role, Macdonald-Miller delivers HVAC, ventilation, and air-conditioning plant work to Vigor Marine LLC on Navy ship repair and modernization tasks — including laundry room ventilation removal and reinstall on USS John S McCain (DDG 56), air-conditioning plant condenser cleaning on USS Gabrielle Giffords (LCS 10), and ventilation ducting repair and replacement on multiple vessels, with sub awards dating from October 2024 through November 2025.
