About the company
John R Seiberlich Inc., doing business as Seiberlich Trane, is a Delaware-based for-profit Subchapter S corporation that provides HVAC equipment, building control systems, and mechanical maintenance services to federal agencies as a prime contractor (99% of recent awards) competing in full-and-open procurement with no set-aside designations. The company operates under primary NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors) and concentrates its capability portfolio on chiller services, building controller upgrades and maintenance, TRANE SC+ software licensing and upgrades, air handler rentals, and facility-level HVAC mechanical services.
Seiberlich Trane's customer base is heavily concentrated in defense and veterans affairs infrastructure. The top five funding entities account for 52% of recent awards by count but 96% of combined potential value, led by the Department of the Air Force Air Mobility Command (15 awards, $1.3 million combined potential value), primarily for building controller upgrades and maintenance at Dover Air Force Base in Delaware. The Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 4 anchors the second-largest relationship (14 awards, $788 thousand combined potential value) with chiller services and air handler rental work. Veterans Integrated Service Network 5 holds five awards valued at $498 thousand. The Department of Agriculture Agricultural Research Service Northeast Area maintains eleven awards but with substantially lower average value ($102 thousand combined). Recent representative prime awards include a $329,800 purchase order from Air Mobility Command for building controller upgrades and operations and maintenance at Dover AFB (February 2023), a $249,885 purchase order from Air Mobility Command for TRANE SC+ software update (July 2022), and a $140,372 purchase order from Veterans Integrated Service Network 4 for chiller services in Wilmington, Delaware (September 2026).
Seiberlich Trane holds position on three small parent vehicles: the Dover AFB Multiple Award Construction Contract, Indefinite Delivery Contract V542C529, and Blanket Purchase Agreement V542P4357, each carrying a single recorded task order. Activity has been episodic — three awards in 2022, two in 2023, four in 2024, one in 2025, and one in 2026 — with only one award (combined potential value $140 thousand) scheduled for completion within the next twenty-four months and therefore facing recompete exposure in that window. Combined obligated dollars across all awards total $3 million against $2.8 million in combined potential value, indicating most awards have been fully executed. Seiberlich Trane carries one subcontract award as a sub to Eastern Construction & Electric Inc., performing HVAC mezzanine controls replacement work (June 2024). The vendor's federal footprint reflects a narrow, maintenance-focused capability set anchored to specific facilities in the Northeast, with concentration in HVAC service delivery to Air Force and VA health system customers.
