William A. Harrison, Inc. specializes in the installation, maintenance, and repair of mission-critical HVAC and precision cooling systems for federal facilities, with deep expertise in chiller systems, HVAC controls, and environmental conditioning infrastructure. The contractor delivers comprehensive services for air-cooled precision cooling units, scroll and Daikin chillers, heat exchangers, and integrated control system upgrades, ensuring operational continuity in sensitive environments such as arsenals and research facilities. Their technical proficiency includes system start-up, preventive maintenance, troubleshooting, and lifecycle management of mechanical and control components, with a demonstrated ability to execute complex modifications and option-year extensions under tight operational constraints. The firm’s focus on reliability and uptime in high-stakes settings distinguishes it as a trusted provider for facilities requiring uninterrupted thermal regulation. The company maintains a strong, recurring relationship with the Department of Defense, delivering HVAC services at critical installations like Pine Bluff Arsenal, including maintenance for quality evaluation facilities and chiller replacements. It also supports the Department of Health and Human Services with chiller maintenance for health-related infrastructure and has provided specialized electrical equipment procurement for chiller control upgrades under the Department of Justice. These engagements reflect a pattern of long-term, mission-critical support rather than one-off procurements. Operating primarily under NAICS 238220, the firm is positioned as a specialized mechanical contractor serving federal infrastructure with a focus on thermal systems integration. Their market niche lies in maintaining and modernizing aging HVAC assets in government buildings where precision temperature control is essential. The company is structured as a small business (2L) based in Little Rock, Arkansas, with no federal certifications listed. Its geographic presence is centered in the central U.S., serving federal installations with localized responsiveness and technical depth in HVAC systems.
