American Combustion Industries Of Delaware, Inc.

American Combustion Industries of Delaware, Inc., doing business as American Combustion Industries, is a Glenn Dale, Maryland–based mechanical and facility support contractor that operates as a prime contractor (90% of recent awards) on federal boiler systems, HVAC equipment, and facility maintenance work. The vendor is a self-certified small disadvantaged business and Department of Transportation–certified Disadvantaged Business Enterprise competing full-and-open, with no set-aside designations applied to any of its recent federal awards.

The vendor's capability portfolio centers on boiler combustion testing, HVAC repairs, equipment installation, emergency facility support, and mechanical infrastructure maintenance. Representative prime work includes a $6.27 million firm-fixed-price contract awarded by Naval Facilities Engineering Command on June 30, 2025, to install three additional temporary boilers at a Bethesda, Maryland facility (completion October 30, 2026); a $1.43 million definitive contract from the same command on May 5, 2025, for temporary boiler installation in Building 16 (completion April 23, 2026); and a $436 thousand emergency de-aeration tank rental purchase order from Veterans Integrated Service Network 5 awarded October 11, 2023 (completion August 10, 2024). Smaller routine work includes steam tunnel repairs, shaft bearing replacements on air handling units, boiler annual tuning, and tank replacement services at facilities across the Washington, D.C., Maryland, and Virginia region.

Customer concentration is diffuse across federal agencies but anchored by defense and civilian facility operations. The top five customers by award count (37% of awards) are the Department of the Navy Office of Naval Research (17 awards, $310 thousand combined potential value), the Department of the Navy Naval Air Systems Command Naval Air Warfare Center (9 awards, $3.8 million), the Department of the Army Installation Management Command Northeast Region (8 awards, $615 thousand), the Department of the Army Corps of Engineers Engineering Support Center Huntsville (8 awards), and the Smithsonian Institution (7 awards, $182 thousand). When ranked by potential value, Naval Facilities Engineering Command dominates (3 awards, $7.7 million combined potential value), followed by Naval Air Systems Command ($3.8 million), the Armed Forces Retirement Home ($2.4 million), the Department of the Treasury Bureau of Engraving and Printing ($2 million), and GSA Public Buildings Service National Capital Region ($860 thousand).

The vendor places task orders under the Utility Monitoring and Control Systems Fifth Generation contract vehicle (6 task orders) and holds seats on the Indefinite Delivery Contract FA706023D0013 (2 task orders) and Blanket Purchase Agreement TEPA0300578 (1 task order), among others. Recent activity has grown substantially — from four awards in 2022 to sixteen in 2025 — with combined potential value across all 132 awards (prime and sub) totaling $20.8 million and combined obligated dollars reaching $21.2 million. Four awards with combined potential value of $6.3 million face ultimate completion within the next twenty-four months and therefore present recompete risk.

As a subcontractor, American Combustion Industries performs boiler maintenance, water heater and tank repair, and piping work under primes including M.C. Cleans (DIA headquarters utility monitoring and maintenance), Johnson Controls Building Automation Systems (water heater and tank replacements at Army National Guard facilities), ASRC Federal Facilities Logistics (Goddard Space Flight Center repairs and maintenance), Koman Sustainable Solutions (lift station and water heating work at military bases), and Weston Solutions (remedial action and excavation support). Service Contract Inventory data show minimal SCI-reportable activity (4 records across FY2022–FY2024, all as named subcontractor, with less than 1.5 FTEs reported across the period), indicating that American Combustion's federal revenue is predominantly captured through goods and purchase orders below the $150,000 SCI reporting threshold rather than through large service contracts.
