What A.O. Reed & Co. does

A.O. Reed & Co. is a 110-year-old commercial mechanical contractor headquartered in San Diego, California, with additional offices in Santa Ana and Los Angeles. The company designs, engineers, fabricates, and installs HVAC, commercial plumbing, and process piping systems for healthcare, biotechnology/pharmaceutical, higher education, government/judicial, and entertainment/hospitality clients across Southern California. It operates the only mechanical contractor-owned ductwork fabrication shop in San Diego and employs the largest union trade workforce in the county under signatory agreements with the Sheet Metal Workers' and Plumbers & Pipe Fitters unions.

The company's core technology comprises in-house sheet metal, plumbing, and pipe fitting fabrication shops (operating since the late 1960s) and a BIM-enabled pre-construction and project coordination function. Its process piping division serves pharmaceutical, biotech, and food & beverage customers with capabilities spanning USP Water, WFI, Pure Steam, and CIP systems, plus specialty alloy welding (Carbon Steel, 304/316L, AL6XN, Hastelloy, 2507 super duplex stainless) and autonomous orbital welding. Notable technical achievements include fabricating what SMACNA considers the largest ductwork ever (248" x 142") and contributing to LEED Silver, Gold, and Platinum-certified projects.

A.O. Reed's revenue model is project-based, combining one-time construction contracts (secured via Design-Build, Design-Assist, and Plan-Spec delivery through competitive bidding and direct owner/GC negotiation) with recurring service and maintenance contracts on installed HVAC and plumbing systems. Pre-construction consulting and prefabrication are positioned as schedule- and cost-saving levers for enterprise customers. The company operates as a subsidiary of Legence, was ranked #31 on ENR's Top 50 Mechanical Firms list in 2023 (up from #43, with 54% revenue growth from 2021–2022), and has delivered landmark projects including Petco Park, the IQHQ RaDD Life Science District, Camp Pendleton Hospital, and the San Diego Central Courthouse.
