Combustion Service & Equipment Co

Combustion Service & Equipment Co, doing business as Cs&E, is a woman-owned small business that manufactures, installs, and maintains boiler, burner, stoker, and HVAC systems for federal facilities as a prime contractor, with minimal subcontract exposure. Based in Pittsburgh, Pennsylvania, and registered as a Subchapter S corporation since January 2002, Cs&E competes exclusively in full-and-open procurements — none of its 38 recent awards carry small-business set-asides despite its woman-owned designation. The firm operates across two dominant NAICS categories: Plumbing, Heating, and Air-Conditioning Contractors (10 awards) and Air-Conditioning and Warm Air Heating Equipment Manufacturing (9 awards), with corresponding PSC footprint in maintenance and repair of plumbing, heating, and steam-plant equipment.

Cs&E's federal customer base is heavily concentrated in the Department of Veterans Affairs, which accounts for 68% of award count and dominates potential value. Veterans Integrated Service Network 4 (Pittsburgh-area facilities) anchors the relationship with 15 awards worth $1.4 million in combined potential value, while Veterans Integrated Service Network 5 (West Virginia and surrounding regions) contributes 4 awards totaling $286 thousand. Beyond the VA, Cs&E has worked with the Department of the Army Installation Management Command Southwest Region ($420 thousand, one award), the Federal Bureau of Investigation's Criminal Justice Information Services Division ($187.8 thousand definitive contract running through May 2027), the Department of the Navy's Naval Sea Systems Command ($72.6 thousand for duct fabrication), and the Department of Justice Federal Bureau of Prisons facilities (multiple small orders, $44 thousand to $34 thousand ranges). Recent representative work includes a $106.5 thousand firm fixed-price purchase order from VA Pittsburgh Healthcare System for boiler preventative maintenance and inspection (awarded June 2026, running through June 2027), a $214.7 thousand urgent boiler repair order for a VA Philadelphia facility (September 2025), a $135 thousand emergency boiler repair at a VISN 5 medical center (June 2025), and a $72.6 thousand small-business procurement from Naval Sea Systems Command for insulated incinerator exhaust duct fabrication at Naval Surface Warfare Center Carderock (September 2024).

Award activity shows volatility — two awards in 2022, one in 2023, five in 2024, four in 2025, and one in 2026 — with combined potential value of $2.4 million across all 38 awards. Notably, obligated dollars total $3 million, exceeding potential value by 22%, suggesting contract modifications and task expansions. Two awards totaling $294 thousand reach ultimate completion within the next twenty-four months, creating recompete exposure. Cs&E holds one minor subcontract role: a boiler maintenance task under Fluor Marine Propulsion's Naval Nuclear Laboratory management and operations contract, with a $1 million funding increase modification (August 2024). The vendor operates without parent-vehicle positioning — all awards are direct purchase orders or definitive contracts issued by customer agencies rather than seats on GWACs, BPAs, or agency-wide IDIQs. Customer agencies span 11 distinct federal organizations, but concentration risk is acute: the VA alone accounts for over half the award count and potential-value share, with the largest non-VA customer (Army) contributing a single $420 thousand award.
