American Combustion Industries Of Delaware, Inc.

American Combustion Industries Of Delaware, Inc. (doing business as American Combustion Industries) operates as a prime contractor on boiler systems, HVAC equipment, and facility maintenance services for federal agencies, with 90% of recent awards held as prime and 10% as subcontracted work. The company is a self-certified small disadvantaged business and Department of Transportation-certified disadvantaged business enterprise based in Glenn Dale, Maryland, competing predominantly in full-and-open procurements without set-aside designations across a portfolio of 133 awards spanning from 1995 through September 2026.

The vendor's core capability centers on boiler tuning and combustion testing, temporary and permanent boiler installation and rental, HVAC equipment repair and maintenance, de-aeration and hot-water tank services, and steam-system infrastructure support. Representative prime awards include a $9 million firm fixed-price definitive contract from Naval Facilities Engineering Command (awarded June 2025) for installation of three additional temporary boilers and one-year rental extension at Bethesda, Maryland; a $2.26 million NAVFAC contract (May 2025) for temporary boiler installation in Building 16 and rental extension; a $436 thousand purchase order from Veterans Integrated Service Network 5 (October 2023) for emergency de-aeration tank rental services at Perry Point; and a $268 thousand emergency de-aeration tank repair contract with VISN 5 (August 2023). Smaller routine maintenance orders span the Smithsonian Institution ($182 thousand combined across seven awards for Natural History Building mechanical services and steam-tunnel repairs), the Social Security Administration ($37.6 thousand for boiler tuning), and the District of Columbia Courts (DC Courts HVAC unit repair under a multi-option Blanket Purchase Agreement structure).

Customer concentration by dollar value reflects Naval infrastructure dominance. Naval Facilities Engineering Command anchors the portfolio with three awards carrying $11.3 million in combined potential value; Naval Air Systems Command and Naval Air Warfare Center account for nine awards and $3.8 million; Armed Forces Retirement Home contributes three awards worth $2.4 million; and the Department of the Treasury Bureau of Engraving and Printing holds six awards valued at $2 million. By award count, the Office of Naval Research leads with seventeen awards at $310 thousand combined potential, followed by Naval Air Systems Command (nine awards, $3.8 million), Army Installation Management Command Northeast Region (eight awards, $615 thousand), and Army Corps of Engineers Engineering Support Center Huntsville (eight awards). The top five customer groupings cover 37% of award count and 83% of combined potential value, with concentration skewed toward Navy infrastructure and facility-support commands. The vendor operates across 32 distinct federal customer agencies, reflecting wide-ranging facility maintenance relationships rather than a narrow customer base.

Work is performed primarily across the Washington, D.C., Maryland, and Virginia region, with specific named locations including Glenn Dale, Bethesda, Greenbelt (NASA Goddard Space Flight Center), and Perry Point (VA medical facility). Place of performance for larger infrastructure contracts is anchored to military installation facilities (Bethesda Naval facilities, Fort Liberty, and joint force headquarters in the National Capital Region) and civilian agency buildings (Smithsonian Institution properties in Washington, D.C., and GSA-managed office space).

The vendor seats on the Utility Monitoring and Control Systems Fifth Generation indefinite-delivery vehicle with six task orders, the Indefinite Delivery Contract FA706023D0013 with two task orders, and a Blanket Purchase Agreement (TEPA0300578) tied to DC Courts HVAC services. The parent-vehicle footprint is modest in scope; most awards are direct purchase orders from customer agencies rather than task orders cascaded from government-wide IDIQs or GWACs.

Activity has grown in recent years—from four awards in 2022 to sixteen in 2025—though recent volume dropped to four awards by September 2026 (a partial-year snapshot). Four awards with ultimate completion dates falling within the next twenty-four months carry combined potential value of $11.4 million and represent recompete exposure in the near term, including the pair of large temporary-boiler contracts with NAVFAC maturing in June and April 2027.

In the subcontractor role, American Combustion Industries delivers boiler preventive and corrective maintenance, water-heater installation, and skilled labor support to M.C. Dean, Inc. (multiple facility maintenance orders at Defense Intelligence Agency headquarters); Johnson Controls Building Automation Systems, LLC (water-heater and heating-system work at Army National Guard facilities); ASRC Federal Facilities Logistics LLC (repair, operations, and maintenance support at NASA Goddard Space Flight Center); Koman Sustainable Solutions, LLC (lift-station pump and water-heating bypass work); and Weston Solutions Inc. (remedial action support at American University). Service Contract Inventory records show minimal SCI-reportable federal service-contract activity—only five sub-contract records across fiscal years 2022 through 2025, with cumulative FTE delivery declining from 1.2 FTEs in FY2022 to zero in FY2025—indicating the vendor's SCI footprint is negligible relative to its prime contracting volume and that goods and repair work dominate the revenue stream outside SCI capture thresholds.
