Hydroaire Mechanical System Inc.

Hydroaire Mechanical System Inc., a woman-owned, veteran-owned, Asian-Pacific American-owned small business, operates as a facilities and building services contractor for the U.S. Coast Guard, delivering specialized mechanical systems, security hardware, and environmental remediation services in full-and-open competitive procurements. The vendor splits its recent footprint evenly between prime purchase orders and subcontracted work under Tridon Corporation, with all activity concentrated at a single customer agency.

Hydroaire's customer base is entirely monolithic — all four recent awards fund Coast Guard operations, with $189 thousand in combined potential value spanning mold remediation, base security systems, mooring hardware replacement, and typhoon recovery building repairs. The Coast Guard sourced two prime purchase orders valued at $90,294 (base security cypher locks at Andersen Air Force Base, Guam, awarded April 24, 2026 with completion targeted for June 30, 2026) and $98,206 (mold remediation services in Hagatna, Guam, awarded July 24, 2023), alongside two subcontract placements under Tridon Corporation for mooring hardware replacement (December 5, 2024) and building repairs at Coast Guard Base Sector Guam related to Typhoon Mawar recovery (December 8, 2025). Activity has remained consistent at one award per fiscal year from 2023 through 2026, with no growth trajectory apparent in the available footprint.

The vendor's concrete capability set centers on mechanical systems installation, plumbing and HVAC services, and environmental remediation — grounded in NAICS classifications across Commercial and Institutional Building Construction, Heavy and Civil Engineering Construction, and Plumbing/Heating/Air-Conditioning Contracting. The source data shows no Service Contract Inventory reporting above the $150,000 threshold; one SCI record captures minimal subcontracted labor (0.8 FTEs in FY2024). The vendor has not secured placement on any named parent vehicles, IDIQs, or GWACs, and all work to date operates through direct purchase orders or subcontractor engagement. Hydroaire does not compete under set-aside designations in its recent award footprint — both prime purchase orders carry no set-aside marking — and shows no pipeline diversity beyond the single customer agency.
