Tri-Mega Mechanical Heating & AC, LLC

Tri-Mega Mechanical Heating & AC, LLC, a Glendale, Arizona–based limited liability company, provides heating, ventilation, and air-conditioning (HVAC) maintenance, repair, and replacement services to federal agencies exclusively as a prime contractor. The vendor competes under full-and-open procurements without set-aside designation and operates across NAICS 232220 (Plumbing, Heating, and Air-Conditioning Contractors) with a facility-focused service portfolio.

Tri-Mega's entire federal footprint concentrates with the Department of Agriculture, specifically the Animal and Plant Health Inspection Service (APHIS) Marketing and Regulatory Programs Business Services division, which accounts for all four recent awards and $48 thousand of the combined $62 thousand potential value. A single $13.5 thousand purchase order from USDA Wildlife Services for RTU package heat pump replacement at a Phoenix facility represents the remainder. All work to date has been performed in Phoenix, Arizona. Recent representative awards include a $17.8 thousand firm-fixed-price contract with APHIS for inspection, preventative maintenance, and repair of HVAC systems (8 package units, 15 split systems, and 2 evaporative coolers) at the APHIS Phoenix Station through May 2026; a $12.2 thousand purchase order for cold box air-conditioning replacement services at a USDA facility in August 2025; and an $18.2 thousand definitive contract under option year four of a five-year base for quarterly preventative maintenance of cooling units, with ultimate completion in May 2030.

Activity is minimal and sporadic — one award annually across 2021, 2022, 2025, and 2026 — suggesting either a small vendor relationship or a narrow niche. The vendor operates exclusively as a prime contractor with no recorded subcontractor activity. Tri-Mega maintains active SAM registration since August 2017 and has demonstrated repeat-customer capability across multiple APHIS Phoenix facilities.
