Mesa Energy Systems, Inc.

Mesa Energy Systems, Inc., doing business as Emcor Services Mesa Energy, is a subsidiary of Wasatch Electric that provides HVAC maintenance, repair, and replacement services to federal agencies primarily as a prime contractor (88% of recent awards) on a full-and-open competitive basis with no set-aside designations. The company is headquartered in Irvine, California, and competes in NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors) and related mechanical construction categories.

Mesa Energy Systems' customer base concentrates heavily in defense and civilian facility maintenance. The top five customers by award count account for 62% of recent awards, led by the Department of Veterans Affairs Veterans Integrated Service Network 22 (76 awards, $6.6 million combined potential value) and the Department of the Navy Naval Facilities Engineering Command (31 awards, $127.8 million). However, the potential-value rankings diverge sharply: NAVFAC and the Marine Corps dominate dollars ($127.8 million and $57.7 million respectively across 38 awards combined), while the VA's many smaller emergency-repair and maintenance calls drive award volume. GSA Region 9 ranks third by value at $18.2 million across 10 awards, primarily for federal building HVAC and cooling-system work. The company also serves the Department of Justice Bureau of Prisons, the Indian Health Service, and the Coast Guard across 34 distinct customer agencies.

The centerpiece of Mesa Energy Systems' prime footprint is a $20 million indefinite-delivery, indefinite-quantity contract with Naval Facilities Engineering Command running through September 2026, covering 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 placed multiple major delivery orders, including a $3.47 million boiler work delivery order at Camp Pendleton North (awarded June 2023), a $2.9 million boiler delivery order at Camp Pendleton (awarded March 2022), a $1.495 million time-extended boiler and mechanical services order (awarded April 2025), and a $574,525 pool-boiler replacement delivery order at Camp Pendleton (awarded August 2025). Outside the NAVFAC IDIQ, Mesa Energy holds a GSA Multiple Award Schedule contract and has received notable prime awards including a $7.53 million design-build contract from GSA Region 9 for emergency cooling-tower replacement and structural repairs at the Federal Building in Los Angeles (awarded February 2024, completion October 2025), a $365,950 VA air-handler replacement at Phoenix (awarded July 2024), a $570,181 VA HVAC system repair and upgrade at the VALOR Building in Loma Linda (awarded May 2022), and a $365,659.87 Indian Health Service contract for HVAC and mechanical troubleshooting and repair at a Hemet, California facility (awarded December 2022, running through December 2027). Recent smaller awards include an $80,400 purchase order from VA Fresno for after-hours emergency HVAC technician service calls (awarded September 2026), a $30,310 Coast Guard chiller repair at Base Los Angeles Long Beach (awarded July 2026), and multiple chiller repairs, inspections, and emergency system replacements at Federal Correctional Institution Herlong, Federal Correctional Institution Mendota, and various VA medical centers.

Activity has tracked unevenly—14 awards in 2022, declining to 9 in 2023 before rising to 18 in 2024, then dropping to 9 in 2025 and 5 awarded year-to-date in 2026. Three awards (combined potential value $1.9 million) reach ultimate completion in the next twenty-four months, presenting minimal recompete cliff exposure in that window. In its subcontractor role, Mesa Energy Systems delivers HVAC controls, boiler work, and mechanical installation services to primes including Harper Construction Company, Chugach Solutions Enterprise, Johnson Controls Building Automation Systems, I.e.-Pacific, OCS Construction Services, Pundir Group, and Dawson Enterprises on federal facility repair and maintenance projects at Naval Air Station Lemoore, Marine Corps Base Camp Pendleton, Naval Base Coronado, and other defense and civilian installations.

SCI-reportable invoiced revenue on federal service contracts totaled $7.6 million across FY2024–FY2025, with FY2025 accounting for $7.4 million across 1.9 government-delivered FTEs at the contract level. Government-paid hourly rates on prime SCI contracts run a median of $603.86 per hour, with the 10th percentile at $217.68/hr and the 90th percentile at $990.04/hr, reflecting a workforce spanning technician through engineering-level roles. Across SCI-reportable prime contracts, subcontractors performed 51% of total contractor hours, with two named subcontractors tracked in the dataset. Mesa Energy competes primarily as a prime builder of its own delivery teams rather than as a subcontractor, though it maintains regular sub relationships with larger facilities and construction primes. The company holds two active GSA Schedule labor categories at rates between $233.55 and $253.18 per hour for HVAC service technicians and power-metering installation specialists, with no security-clearance positions in the portfolio.
