Mesa Energy Systems, Inc.

Mesa Energy Systems, Inc., doing business as Emcor Services Mesa Energy, a subsidiary of Wasatch Electric and part of the EMCOR Group, delivers mechanical and electrical construction, HVAC maintenance, boiler replacement, and facility infrastructure repair services to federal agencies as a prime contractor (88% of recent awards) on a full-and-open competitive basis with no small business set-asides. The company is based in Irvine, California, and operates under primary NAICS category 238220 (Plumbing, Heating, and Air-Conditioning Contractors).

Mesa Energy's customer concentration is dominated by defense and civilian infrastructure customers. The top five funding agencies account for 93% of combined potential value, led decisively by the Department of the Navy's Naval Facilities Engineering Command (31 awards, $127.8 million combined potential value) and the United States Marine Corps (7 awards, $57.7 million). The Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 22 places the highest volume (76 awards) but carries lower potential value ($6.6 million), indicating a steady stream of small emergency and maintenance calls. The General Services Administration Public Buildings Service Region 9 contributes 10 awards valued at $18.2 million. This volume-versus-dollars divergence reflects Mesa Energy's role as both a large-project contractor for Navy boiler and mechanical infrastructure and a responsive emergency-repair vendor for VA facilities and Bureau of Prisons institutions.

Mesa Energy holds a $20 million indefinite delivery, indefinite quantity multiple award contract with Naval Facilities Engineering Command running through September 2026 for boiler and mechanical maintenance, construction, and repair services at Marine Corps Base Camp Pendleton and Naval Weapons Station Seal Beach in California. Under this IDIQ, Mesa Energy has executed multiple delivery orders totaling approximately $8.41 million, including a $3.47 million boiler replacement at Building 520591 (awarded June 29, 2023, scheduled completion March 15, 2025), a $2.9 million boiler work order at Building 210628 (awarded March 23, 2022, completed September 19, 2023), and a $1.495 million time-extended boiler and mechanical services order (extended to October 20, 2026). Mesa Energy also places task orders under the GSA Multiple Award Schedule (52 task orders, $9.5 million combined potential value), with named vehicle citations including NAVFAC SW HVAC Systems MACC 2011–2016 (11 task orders, $29.4 million) and other indefinite delivery contracts. Representative prime awards include a $7.53 million design-build contract with GSA Region 9 for emergency cooling tower replacement and structural repairs at the Federal Building at 300 North Los Angeles Street (awarded February 29, 2024, scheduled completion October 23, 2025); a $574,525 pool boiler removal and replacement delivery order at Camp Pendleton North Building 1315 (awarded August 21, 2025, scheduled completion August 21, 2026); and a $370 thousand boiler and mechanical construction order at Naval Base Coronado (awarded August 7, 2024).

Activity peaked in 2024 with eighteen awards but declined to three awards by April 2026, suggesting a post-peak trajectory; only three awards (combined potential value $2.4 million) reach ultimate completion in the next twenty-four months, placing minimal recompete exposure in the near term. The source data spans 224 total awards from 2001 to April 2026, with recent years showing 2022: 14 awards, 2023: 9 awards, 2024: 18 awards, 2025: 9 awards, and 2026: 3 awards year-to-date.

In its subcontractor role, Mesa Energy delivers HVAC and boiler work to Harper Construction Company on Marine Corps barracks and operations complex upgrades; to Chugach Solutions Enterprise on HVAC unit maintenance and repair programs; to Johnson Controls Building Automation Systems on boiler replacement; to I.e.-Pacific on Navy base facility repairs; to OCS Construction Services on roof and HVAC work at federal ports of entry and Los Angeles federal building upgrades; and to Pundir Group on boiler and chiller maintenance at GSA federal buildings. The vendor subcontracts on approximately 12% of its awards by count.

SCI-reportable federal service contracting captured only $208 thousand in invoiced revenue (FY2024) across 1.0 FTEs at a median government-paid rate of $121.14 per hour; this narrow SCI footprint reflects the vendor's emphasis on goods, construction deliverables, and equipment repair rather than labor-hour services. Mesa Energy's GSA Schedule labor categories span HVAC service and installation and power metering installation, priced at $233.55 to $253.18 per hour, requiring high school equivalent to other technical school certification and five to ten years of experience, with no security-clearance requirements.
