Jackson Mechanical Service Inc.

Jackson Mechanical Service Inc., an Oklahoma City-based HVAC and mechanical contracting company with over fifty years of operational experience, provides emergency repair, preventative maintenance, and equipment-rental services for federal facility infrastructure as a prime contractor (95% of awards) predominantly in the full-and-open market, with occasional total small business set-asides. The company operates across NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors) with PSC concentration in refrigeration and air-conditioning equipment maintenance and industrial boiler repair.

Customer concentration is acute and geographically bound. The Department of Veterans Affairs Veterans Integrated Service Network 19 accounts for 42 awards (79% coverage of recent award count) and $5 million combined potential value (98% of combined dollars) — essentially all of Jackson Mechanical's federal work. The next-tier customers are marginal: the Department of Agriculture Agricultural Research Service Plains Area (8 awards, $145 thousand), the Department of Justice Bureau of Prisons Federal Transfer Center Oklahoma City (8 awards, $181 thousand), and the Department of the Air Force Materiel Command (3 awards across two customer lines, $302 thousand). This dependency on a single customer network within VISN 19 — a single VA regional integrated service network covering Oklahoma and surrounding states — reflects Jackson Mechanical's operational footprint as a regional emergency-response contractor for VA medical facility infrastructure rather than a national multi-agency provider.

Work performed is tactical and episodic: emergency chiller, boiler, and air-handling-unit repairs; cooling-tower motor replacement; steam coil and water-coil replacement; equipment rentals (120-ton chillers, 600-ton cooling towers, boilers). Recent representative contracts include a $588.7 thousand definitive contract from VISN 19 (Aug 2025) for emergency cooling repair at the Oklahoma City Health Care System, a $258.9 thousand firm fixed-price purchase order (Jun 2022) for chiller preventative maintenance services, a $258 thousand contract (May 2025) for emergency boiler and chiller service at the Lawton Outpatient Clinic at Fort Sill, and a $48.9 thousand total small business set-aside (Mar 2026) from the USDA Agricultural Research Service for chiller repair at the Grazinglands Research Laboratory in El Reno, Oklahoma. Jackson Mechanical sits on the GSA Multiple Award Schedule with four recorded task orders and participates in the Utility Monitoring and Control Systems Fifth Generation vehicle with one task order.

Activity runs at a steady low volume — four to six awards per year across the past five years — with five awards worth $588 thousand approaching ultimate completion within the next twenty-four months and therefore exposed to recompete. The company has subcontracted to J&J Maintenance Inc., Johnson Controls Building Automation Systems LLC, and M.C. Cleansvendornametrait.phpdean Inc. on operations and maintenance work at Tinker and Vance Air Force Bases supporting the Defense Health Agency, equipment-replacement work for Army Corps of Engineers, and facility-maintenance work for the Defense Information Systems Agency. Service Contract Inventory captures minimal activity: zero invoiced revenue in SCI-reportable prime records (FY2022–FY2024), with the vendor appearing as a named subcontractor on three records across FY2022 and FY2024 at negligible FTE scale. SCI undercount is expected given Jackson Mechanical's heavy placement in purchase-order work under the $150,000 reporting threshold and equipment-rental contracts.
