ACCO Engineered Systems

Since 1934, owners and builders have selected ACCO Engineered Systems to design, install, and maintain more than 250,000 mechanical projects. ACCO is dedicated to the design, fabrication, installation, maintenance and service of commercial and industrial HVAC, refrigeration, plumbing, process piping, and building automation systems. The company was founded in Los Angeles as Air Conditioning Company, a proprietorship, and moved to Glendale in 1949, where it changed from an air conditioning distributor into an independent corporation. It took the name ACCO Engineered Systems in 2002 and is now headquartered in Pasadena, California.

This integrated delivery system provides customers with the most practical, cost effective solutions for their particular mechanical and control system requirements. Through innovative engineering, comprehensive design solutions, consistent work quality, and qualified maintenance; ACCO confidently delivers the best possible solution.

Its services also include BIM and VDC, sheet metal, rigging, fire sprinklers, site utilities, chiller service, preventive maintenance and 24/7 service calls.

Over the years, we've grown at a dynamic pace, becoming one of the largest mechanical contractors in the country. To accommodate our increasing product offerings, we’ve expanded with Sunbelt Controls, Sunbelt Electric, Smith MEP, Geo. H. Wilson, PLS Companies and AES Industrial. Including its subsidiaries, the company has more than 5,000 employees and offices and manufacturing campuses at more than 40 locations, and it holds licenses in states such as California, Arizona, Washington, Texas, Colorado and Hawaii. What’s great about working here is that we’re a big enough company to be the leader in HVAC mechanical contracting in California and the Southwest U.S., but as a 100% employee-owned ESOP, we’re a private company with a family-oriented feel. Together, the employees of ACCO are comprised of intelligent, dedicated, and entrepreneurial team members who enjoy what they do. Several of our employees have worked at ACCO for twenty-five, thirty, and even over forty years! Follow our page to receive updates and job posting notifications.
