Acco Engineered Systems, Inc.

Acco Engineered Systems, Inc., a for-profit Subchapter S corporation headquartered in Pasadena, California, provides commercial and industrial HVAC, refrigeration, plumbing, building automation, and facility maintenance and repair services to federal agencies as a prime contractor (96% of recent awards). The company operates without SBA set-aside designations and competes in the full-and-open federal marketplace. Acco maintains two named subsidiaries, Sunbelt Controls, Inc. and Sunbelt Electrical Company, Inc., which extend its capability framing into building controls and electrical infrastructure.

Acco's federal work spans facility systems maintenance, emergency repairs, and infrastructure upgrades across civilian and defense agencies. Representative prime awards include a $228,861 sole-source firm fixed-price purchase order from Naval Air Warfare Center (awarded November 2025) for chiller repair services; a $299,914 delivery order from the Department of Agriculture's Pacific West Area (awarded September 2022) for repair and replacement of PACO and Grundfos pumps, vents, and cooling tower controls; a $288,706 purchase order from the Department of Energy's Western Area Power Administration (awarded September 2021) for replacement of thirteen HVAC systems across seven locations; and a $195,173 purchase order from the National Oceanic and Atmospheric Administration (awarded September 2021) for HVAC preventative maintenance and emergency repairs at the NMFS Santa Cruz Lab through September 2026. The majority of Acco's footprint, however, consists of task orders under standing BPAs and GSA Multiple Award Schedule contracts—smaller individual awards but high aggregate volume. A $6 million single-award BPA with the Department of Veterans Affairs Veterans Health Administration (Veterans Integrated Service Network 20) for maintenance and repair services at the Boise VA Medical Center, running through July 2025, anchors a substantial portion of the company's VA activity and has generated more than 130 task orders for HVAC, electrical, plumbing, elevator, fire suppression, geothermal, and grounds maintenance work.

Customer concentration is pronounced within the VA system. The top five customer agencies account for 44% of all awards and 38% of combined potential value. Veterans Integrated Service Network 20 alone represents 139 awards worth $6.9 million combined potential value. Veterans Integrated Service Network 10 contributes 31 awards valued at $5.4 million. The Department of Agriculture's Pacific West Area represents 40 awards worth $3.8 million, primarily for facility systems repairs at research and power-generation sites in the Western region. Veterans Integrated Service Network 22 (44 awards, $3.2 million) and Veterans Integrated Service Network 4 (10 awards, $1.3 million) complete the high-concentration set. This VA dominance reflects Acco's position as a recurring facility-maintenance vendor for Veterans Health Administration regional networks rather than a strategic partner on large transformational programs.

Acco's vehicle posture centers on the GSA Multiple Award Schedule, which carries 513 task orders worth $37.9 million combined potential value—the overwhelming majority of the company's federal work. Place of performance spans the continental United States, Hawaii, and overseas military installations (Schriever Space Force Base, Beale Air Force Base, Naval Base San Diego, China Lake, Vandenberg Air Force Base, and others). A single-award $160,000 Blanket Purchase Agreement with the Missile Defense Agency (awarded May 2024, running through May 2028) provides locksmith services across Redstone Arsenal, the National Capital Region, Kirtland Air Force Base, and Vandenberg Air Force Base under the GSA Multiple Award Schedule. The NAVFAC Southwest Small Business MACC vehicle (2017–2022) carried 16 task orders, though this vehicle has concluded. A Facilities Maintenance and Management indefinite delivery contract generated 10 task orders worth $331,000. These structures position Acco as a transactional vendor executing short-cycle, high-velocity task orders rather than as an incumbent prime on large, multi-year system-integration contracts.

Activity has trended downward in recent years. Awards per year declined from 62 in 2022 to 33 in 2023, 29 in 2024, 7 in 2025, and 1 in the first quarter of 2026. Combined potential value across all awards stands at $53.3 million, but combined dollars obligated reach $80.7 million—a signal that task order execution rates exceed ceiling values, reflecting repeat, routine renewal of standing maintenance work. Only three awards face ultimate completion within the next twenty-four months, with a combined potential value of $371,000, indicating limited recompete exposure in the near term given the company's reliance on standing BPAs and MAS task orders that extend through 2025–2028.

Acco operates as a prime on 96% of its awards and as a subcontractor on 4% (25 sub-awards). Sub work includes HVAC and plumbing services under D7, LLC on the Beale Air Force Base visitor control center and aircraft hangar projects (awarded April 2024 and May 2023); chiller replacement work for Johnson Controls Building Automation Systems LLC on an Army Corps of Engineers contract (June 2025); pressure tank repair at Schriever Space Force Base under Olgoonik Enterprises, LLC (November 2025); and building controls and mechanical services under Gilbane Federal, Harper Construction, Legend Construction and Painting, and I.e.-Pacific on base facility modernization and conversion projects (2022–2023). This sub footprint is modest relative to prime volume and reflects selective teaming on larger construction and upgrade programs rather than a core subcontracting business model.

Service Contract Inventory data (covering contracts above the $150,000 federal reporting threshold) shows minimal SCI presence: $486,000 in invoiced amounts across FY2023 (the only year with prime-level reportable revenue), delivered by 0.9 FTEs on a single contract. SCI-derived government-paid hourly rates on prime contracts ranged from $348.56/hr (10th percentile) to $1,364.95/hr (90th percentile), with a median of $856.75/hr, indicating mix of craft labor, technician, and supervisory roles. Across SCI-reportable prime contracts, 17% of total hours were subcontracted. The gap between SCI figures and total award count reflects the fact that the vast majority of Acco's federal footprint consists of task orders and delivery orders under $150,000 or purchase orders for specific equipment and repairs—work not captured in SCI's reportable universe.

GSA Schedule labor rates span eight technical and craft categories priced from $149.87/hr to $217.53/hr, all at the high-school or associate-degree level with no security-clearance requirements. Rates cover Project Engineers, HVAC Controls Technicians, Metering & Controls Technicians, Commissioning Specialists, Electricians, and Pipe Trades Technicians—personnel aligned to Acco's core facility systems business and the small-job, high-velocity task-order model characteristic of GSA MAS ordering.

Acco's federal posture is that of a specialized facility systems vendor competing full-and-open on routine maintenance, repair, and capital renewal work rather than as a strategic prime on major acquisitions. The company's facility maintenance focus (403 awards), plumbing and HVAC contracting work (82 awards), and regional concentration within the VA system and Department of Agriculture create both sticky recurring revenue (standing BPAs) and shallow customer switching costs (task orders can migrate to competitors on next solicitation). Recompete risk is low in the near term given the structure of standing vehicles, but pipeline risk is evident in the declining award velocity over the past three fiscal years.
