What United Mechanical, Inc. does
United Mechanical, Inc. is a privately held commercial mechanical construction and HVAC services company founded in 1975 and headquartered in Oklahoma City, Oklahoma, with a secondary operating presence in Tulsa. It operates three wholly owned divisions: United Mechanical Construction (design/build, new construction, retrofit, pipefitting, sheet metal fabrication, and process piping), United Mechanical Service (24/7 commercial HVAC repair and maintenance in Oklahoma City), and Donohue Commercial Service (the Tulsa service operation). The company is described as the largest employer of plumbing, pipefitting, and sheet metal tradespeople in Oklahoma and runs 37,500 sq ft of fabrication facilities (7,500 sq ft piping, 9,000 sq ft plumbing, 21,000 sq ft sheet metal) equipped with a Vicon coil line system, ESAB plasma and water jet cutting, 90-ton press brake, and pipe fabrication equipment capable of handling pipe up to 30 inches in diameter.
The company's underlying technology stack is built around in-house BIM (Building Information Modeling) for pre-construction mechanical design and NEBB-certified air/water balancing, with fabrication capabilities that the firm states reduce field labor by up to 50%. United Mechanical generates revenue through three primary streams: (1) one-time commercial HVAC construction and installation projects, (2) transaction-based commercial HVAC repair and emergency services priced per job with upfront diagnostic estimates, and (3) a subscription-based Proactive Preventative Maintenance Program with a performance guarantee that covers repairs at no additional cost. Customer segments include hospitals and medical facilities, data centers, universities, banks and financial institutions, industrial and warehouse facilities, commercial offices, houses of worship, and manufacturing facilities, with disclosed marquee projects at Tinker Air Force Base, Oklahoma State University, the University of Oklahoma, Oklahoma Heart Hospital, Will Rogers World Airport, Hobby Lobby, and Baker Hughes.
The go-to-market motion is enterprise field sales in Oklahoma, with direct service relationships to building owners, property managers, and facilities directors, supplemented by competitive bidding and design-build arrangements on commercial construction. United Mechanical has been a member of the LINC nationwide service network since 2012, enabling multi-facility national service contracts across more than 150 affiliated contractors. The company is closely held, with the Rutherford family represented in ownership and leadership, no external private equity or venture capital, and revenue figures that are not publicly disclosed.
