Jackson Mechanical Service Inc.

Jackson Mechanical Service Inc., an Oklahoma City-based HVAC and mechanical contractor with over 50 years of operating history, provides emergency and preventive heating, cooling, boiler, chiller, and related mechanical equipment repair, replacement, and rental services to federal agencies as a prime contractor (95% of awards by count) and selectively as a subcontractor.

The vendor's federal customer base is highly concentrated around a single relationship. The Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 19 accounts for 45 of 81 total awards (55% of awards by count) and $5.3 million of the combined $6 million potential value across the entire portfolio—a concentration of 88% by dollar value. This relationship anchors the vendor's federal footprint; recent VISN 19 awards include a $588,730 definitive contract for emergency cooling repair at Oklahoma City Health Care System (August 2025), a $258,000 purchase order for emergency boiler and chiller service at Lawton Outpatient Clinic (May 2025), a $137,655 order for emergency chiller motor repair (April 2026), and $116,433 for emergency steam coil replacement at the Oklahoma City VA Medical Center (February 2026). The remaining customer base diversifies lightly across the Department of Agriculture Agricultural Research Service (8 awards, $145 thousand), the Department of Justice Bureau of Prisons (8 awards, $181 thousand), and smaller presence with the General Services Administration, Department of Health and Human Services Indian Health Service, and the Air Force Materiel Command. Top NAICS categories reflect the service mix: Plumbing, Heating, and Air-Conditioning Contractors (51 awards) and Commercial and Institutional Building Construction (3 awards), with primary PSC codes in refrigeration and air-conditioning maintenance (16 awards) and industrial boilers (10 awards).

Jackson Mechanical has listed recent awards with both no-set-aside and Total Small Business designations. Recent Total Small Business awards include a $113,476 purchase order for replacement boiler safety relief valves (August 2026) and a $48,931 order for chiller repair at the USDA-ARS Grazinglands Research Laboratory in El Reno (March 2026). The source lists four task orders with the Multiple Award Schedule as parent and one with Utility Monitoring and Control Systems Fifth Generation as parent; it does not establish the vendor's ownership of vehicle seats.

Subcontractor work represents a small, recent addition to the footprint. Jackson Mechanical appears on four sub-awards: October 2025 operations-and-maintenance work with J & J Maintenance Inc. supporting Tinker and Vance; June 2025 pump-flange work with Johnson Controls Building Automation Systems under a DoD pumps-and-compressors vehicle; and two DISA facility-maintenance sub-tasks with M.c. Dean, Inc. (November 2024 cooling-tower replacement at Oklahoma City, October 2023 compressor replacement). The SCI dataset captures minimal volume—zero prime invoiced revenue across FY2022–FY2025, and named subcontractor records in FY2022, FY2024 and FY2025; these limited records do not establish why invoiced amounts are zero.

Activity trajectory remains modest and flat: 6 awards in 2022, declining to 4 in 2023, then 5 in 2024 and 5 in 2025, rebounding to 9 in 2026. Four awards (combined potential value $539 thousand) reach ultimate completion within the next twenty-four months and face recompete exposure, representing a small recompete cliff relative to the vendor's total portfolio.
