What REX Electric & Technologies does

REX Electric & Technologies is a Chicago-headquartered electrical and technology services contractor founded in 1921 by Angelo Perciabosco. The company operates as a subsidiary of Chugach Alaska Corporation following its October 2016 acquisition, and provides integrated electrical construction, lighting, voice/data cabling, security, access control, fire alarm, audio-visual, riser management, and mission-critical data center services. Its service model is organized into two categories, Electrical Services and Technology Services, delivered as a unified offering across new construction, interior build-outs, and ongoing maintenance for general contractors and building owners.

REX employs an enterprise field sales motion targeting general contractors on ground-up and interior build-out projects while maintaining direct relationships with building owners for service and maintenance work. The firm is Minority Business Enterprise (MBE) certified, RCDD-certified for communications distribution design, and a participant in the OSHA Challenge Pilot Program. It operates a fleet of more than 30 service vans supporting 24/7 emergency response throughout the Chicago metropolitan area and broader Midwest. Notable project work spans healthcare (Central DuPage Hospital), higher education (DePaul, DeVry, Midwestern University, Museum of Science and Industry), enterprise technology (Salesforce), and landmark commercial real estate (United Center, Merchandise Mart).

The revenue model is professional services-based with custom project-based pricing, multi-year contracts, and time-and-materials emergency service. Leadership is organized by division under President Patrick Lancaster, with SVP-led lines for Commercial Interiors, Electrical Construction, and Building Services/Operations, plus a Financial Controller. The company does not disclose revenue or funding and operates as a privately held limited liability company under Chugach's diversified commercial services portfolio.
