About the company
Haynes Mechanical Systems, Inc., a Greenwood Village, Colorado-based HVAC and mechanical systems maintenance contractor, operates as a prime contractor delivering heating, ventilation, air-conditioning, and related facility infrastructure repair and maintenance services to seven federal agencies under full-and-open competition, with no set-aside designations across its portfolio. The company is a for-profit Subchapter S Corporation competing exclusively as a prime (100% of recent awards); it holds no federal IDIQs or vehicle seats and does not subcontract federal work.
Haynes Mechanical Systems specializes in commercial HVAC maintenance, emergency facility cooling system repairs, chiller servicing, and CRAC unit replacement — work grounded primarily in NAICS 811310 (Commercial and Industrial Machinery and Equipment Repair and Maintenance) and PSC codes for air-conditioning and heating equipment maintenance. Representative recent work includes a $74,141 definitive contract with the Federal Aviation Administration's Southwestern Region (August 2023 through August 2028) for annual and five-year chiller maintenance at the Denver Air Traffic Control Tower and Terminal Radar Approach Control Facility; a $234,249 purchase order from the United States Mint (January 2022) for HVAC technician services in Denver; a $126,936 CRAC unit replacement purchase order from the Federal Highway Administration's Lakewood facility (February 2023, completed August 2024); and a $17,636 emergency CRAC repair order from the Federal Highway Administration for critical server room cooling (November 2025).
Customer concentration is split unevenly: the Department of the Air Force accounts for 12 awards (42% by count) but ranks fifth in potential value, while the United States Mint drives 42% of combined potential value ($234 thousand) with only two awards. The Federal Highway Administration (four awards, $189 thousand combined potential value) and the Federal Aviation Administration Southwestern Region anchor the next tier. Top customers by award count coverage account for 82% of recent awards across seven distinct agencies.
Activity has been episodic — two awards in 2020, one in 2022, two in 2023, one in 2025, and one in 2026 — with total potential value of $562 thousand against obligated dollars of $1 million (180% of potential, indicating contract modifications and closeouts exceeding original ceilings). Two awards (combined potential value $78 thousand) face ultimate completion inside the next twenty-four months. The vendor carries a SAM.gov registration history dating to 2002 and operates without identified subcontractors or parent relationships; it competes for task orders under Air Force indefinite delivery contracts (three separate IDCs with one task order each) and a General Services Administration Blanket Purchase Agreement (two task orders, $9 thousand combined potential value).
