What ACCO does
ACCO, Inc. is a privately held commercial HVAC contractor founded in 1958 and headquartered in Louisville, Kentucky. The company provides installation, service, design-build, and preventive maintenance for heating, air conditioning, refrigeration, and temperature control systems, serving commercial facilities in Kentucky and Southern Indiana. Its service portfolio spans building automation, HVAC equipment installation and renovation, sheet metal fabrication, backflow preventer testing, and 24/7/365 emergency service. ACCO holds Kentucky State HVAC License HM03744 and Kentucky Boiler License 1695 and maintains union affiliation with UA Local 502 alongside memberships in MCAA, MSCA, and MCAKY.
The company's core technical capability is building automation system design and installation by factory-certified technicians, enabling remote monitoring and control of buildings through a web browser and interoperability with mechanical, OEM, and lighting systems via the BACnet protocol. ACCO positions itself as a Carrier Controls Expert, with specialization in Carrier building automation and HVAC control system deployments. The company has executed large-scale data center HVAC projects, including the CoreSite LA3 facility in Los Angeles (180,000 square feet, three 1,500-ton chillers, 27 CRAH units, 44 tons of VRF split systems, and prefabricated piping up to 20 inches in diameter with six months of BIM coordination).
Revenue is generated through a sales-led direct distribution model combining one-time installation projects, recurring preventive maintenance agreements, and professional design-build services. Pricing is quote-based and not publicly disclosed. The company is independently owned with no disclosed institutional investment, parent company, or subsidiary structure. Customer acquisition relies on direct sales engagement, online quote requests, and a content marketing presence via the company website blog and social sharing channels. Compliance platform registrations (ISN, Avetta) prequalify ACCO for enterprise facility vendor programs.
