Acco Engineered Systems, Inc.

Acco Engineered Systems, Inc., a Pasadena, California-based for-profit Subchapter S corporation, delivers HVAC, plumbing, building automation, refrigeration repair, and commercial facility maintenance services to federal agencies as a prime contractor on 96% of recent awards, competing full-and-open without set-aside designations.

Acco operates through three named subsidiaries — Sunbelt Controls, Inc., Sunbelt Electrical Company, Inc., and Smith Mechanical-Electrical-Plumbing — that expand its capability envelope into controls and electrical integration alongside core mechanical trades. The parent company headquarters in Pasadena serves as the administrative hub for a portfolio anchored in facility maintenance, mechanical systems repair, and building infrastructure support delivered across civilian federal installations. The vendor does not hold SBA certifications under 8(a), HUBZone, SDVOSB, WOSB, or other set-aside categories; all work flows through full-and-open competition or GSA Schedule vehicles.

Customer concentration sits heavily with the Department of Veterans Affairs. The top five customer agencies account for 44% of recent awards by count: VA Veterans Health Administration Veterans Integrated Service Network 20 leads with 139 awards valued at $6.9 million, followed by VA VISN 10 (31 awards, $5.4 million), the USDA Agricultural Research Service Pacific West Area (40 awards, $3.8 million), VA VISN 22 (44 awards, $3.2 million), and the Department of Homeland Security Coast Guard (20 awards, $441 thousand). The VA dominates both volume and dollar share — multiple VISNs collectively anchor the top of the customer concentration. Representative prime work includes a $269 thousand Air Force computer room air conditioning maintenance, repairs, and replacement contract at Joint Base Lewis-McChord (Total Small Business set-aside, awarded September 2023), a $228.9 thousand Naval Air Warfare Center chiller repair sole-source procurement at China Lake (November 2025), a $180.7 thousand Department of Energy cold storage coil project in Aberdeen, Idaho (June 2023), and extensive task order work under a $6 million VA blanket purchase agreement for facility maintenance at the Boise VA Medical Center running through July 2025. Acco also holds a $160 thousand Missile Defense Agency BPA for locksmith services across Redstone Arsenal, the National Capital Region, Kirtland Air Force Base, and Vandenberg Air Force Base (May 2024 through May 2028).

Acco's vehicle position centers on the GSA Multiple Award Schedule, where 513 task orders represent $37.9 million in combined potential value — the overwhelming majority of the vendor's placement strategy. A smaller subset sits on NAVFAC SW Small Business MACC 2017-2022 (16 task orders), a Facilities Maintenance and Management indefinite delivery contract (10 task orders, $331 thousand), and individual IDCs with the VA and MDA. The vendor competes full-and-open on the MAS without reliance on set-aside vehicles.

Activity trajectory shows decline from historical peak. The vendor recorded 62 awards in 2022, falling to 33 in 2023, 29 in 2024, 7 in 2025, and only 3 in 2026 through July. This contraction signals a sustained downward trajectory rather than a seasonal fluctuation. Only 3 awards (combined potential value $283 thousand) complete within the next twenty-four months, reducing near-term recompete exposure but underscoring the need for pipeline replenishment across the vendor's primary customer base.

Acco operates predominantly as a prime (596 of 623 total awards, 96%), with subordinate subcontract exposure to construction primes including Chinn Construction (Seattle passport project, May 2026), Olgoonik Enterprises (pressure tank replacement at Schriever Space Force Base, November 2025), Johnson Controls Building Automation Systems (chiller replacement, June 2025), D7 LLC (Beale Air Force Base visitor control center and hangar work, April 2024 and October 2022), Gilbane Federal (aircraft hangar at Beale, May 2023), Legend Construction and Painting (Browning Federal Building elevator and HVAC modernization, July 2022), Harper Construction (controls work at China Lake, July 2022), and I.E.-Pacific (Naval Base San Diego conversion project, January 2022). These sub relationships cluster around military construction and facility renovation where Acco supplies HVAC, plumbing, mechanical, and controls engineering as a trade partner to general contractors.

SCI-reported service contract activity is minimal relative to the vendor's award footprint. Prime SCI records total $486 thousand in invoiced revenue from FY2023 alone, with FY2022, FY2024, and FY2025 carrying zero prime invoicing in the SCI dataset. Government-paid hourly rates on SCI prime records span a median of $856.75 per hour, with 10th percentile rates around $348.56 per hour and 90th percentile rates near $1,364.95 per hour — a wide spread reflecting both technician-level work and senior engineering support. Across SCI-reportable prime contracts, subs comprised an average of 17% of contractor hours, with only one named subcontractor reported. FTE deployment on SCI-reportable work peaked in FY2022 at 1,095 FTEs (3 prime, 5 sub records) and collapsed to 0.2 FTEs in FY2023; FY2024 and FY2025 sub-only activity reported 3.6 and 9.8 FTEs respectively. SCI coverage is a strict subset of the vendor's federal services footprint and does not reflect the full scope of purchase-order and task-order work flowing through the GSA MAS.

The vendor's GSA Schedule labor portfolio spans eight categories priced from $149.87 per hour (project engineer, associates degree, three years experience) to $217.53 per hour (HVAC service technician, high school, five years experience), with intermediate roles including metering and controls technician ($164.45/hr), HVAC controls technician ($164.45/hr), commissioning specialist ($203.05/hr), electrician ($210.74/hr), and pipe trades technician ($214.07/hr). No security-cleared labor is offered. This pricing and capability mix aligns with Acco's core positioning in building systems operations, maintenance, and emergency repair across civilian federal real estate.

The category concentration reflects Acco's specialization: facilities support services account for 403 awards, plumbing/heating/air-conditioning contractors for 82 awards, and commercial and institutional building construction for 31 awards. The top product service codes track to HVAC and plumbing maintenance (85 awards), refrigeration and air conditioning equipment maintenance (49 awards), miscellaneous equipment maintenance (33 awards), and hospital facility maintenance (30 combined awards). This portfolio is characteristic of a regional facilities maintenance and mechanical trades contractor embedded in VA hospital networks and civilian federal installations, without meaningful diversification into IT, professional services, construction management, or other non-trades domains.
