About the company
Antonio C. Mendoza III, doing business as Antonio C Mendoza III and operating as Tony's Workshop, is a Guam-based veteran-owned, minority-owned (Asian-Pacific American), self-certified small disadvantaged business sole proprietorship that delivers HVAC maintenance, chiller rental, fire protection system repair, and facilities maintenance services to Department of Defense installations in the Pacific region, primarily as a prime contractor (89% of recent awards) on full-and-open purchase orders and delivery orders with no set-aside designations.
The vendor's customer footprint concentrates heavily on Pacific-based military facilities. The Department of the Air Force Pacific Air Forces dominates both volume and value—18 awards worth $5.3 million combined potential value—representing 32% of total awards and 58% of combined potential value across the vendor's recent footprint. The Department of the Navy, Department of the Army Guam Army National Guard, and Department of Homeland Security US Coast Guard round out the top four customer agencies, together accounting for 77% of recent awards. The 94%-coverage customer ranking by potential value surfaces a secondary concentration: the Department of the Navy United States Pacific Fleet Forces, with four awards worth $1.4 million, appears only in the dollar ranking, reflecting larger individual orders placed against fewer Navy task orders than the frequency-based ranking shows.
Mendoza's largest vehicle position is the Department of the Air Force Pacific Air Forces single-award Indefinite Delivery Contract (IDC) valued at $3 million (awarded May 1, 2023, expiring December 31, 2025) for hoods, ducts, and fire protection system maintenance and repair at Andersen Air Force Base in Yigo, Guam. Four delivery orders totaling approximately $1.04 million have been issued against this IDC as of the source date, leaving $1.96 million in remaining capacity. Representative prime work includes a $331,340 delivery order (January 2025) for hoods, ducts, and fire protection services under the Air Force IDC; a $186,685 firm fixed-price purchase order from the Coast Guard (September 2026) for HVAC work at Base Guam Building 2; and a $151,130 chiller rental purchase order from the Coast Guard (August 2026). Activity has remained modest—four awards in 2022 to nine in 2024, dropping to one in 2025 and five in 2026—with only $245 thousand in combined potential value facing completion within the next twenty-four months. In its subcontractor role, the vendor performs equipment procurement and installation work for Asrc Federal Facilities Logistics under Navy and Army IDCs, delivering E-TEC water-cooled chiller units (June 2024 sub-awards) and has provided unspecified services to Serco Inc. (April 2024). The vendor's capability footprint centers on HVAC systems, chiller provision and maintenance, fire suppression and exhaust systems, electrical services, and general facilities repair—work classified primarily under NAICS 481511 (Other Electronic and Precision Equipment Repair and Maintenance, 12 awards), 238220 (Plumbing, Heating, and Air-Conditioning Contractors, 8 awards), and PSC Air Conditioning Equipment and Maint/Repair/Rebuild Of Equipment codes.
