About
With over 70 years of combined ownership experience and nearly three decades serving Chicagoland since 1995, Dunning Electrical Services, Inc. brings deep commercial and industrial electrical expertise to facility managers, property owners, and general contractors across the Chicago metro. The company operates as a full-service electrical contractor handling everything from underground utility work and site lighting to motors and controls, backup generators, EV charging station installations, and building automation systems. For facility managers overseeing multi-tenant or high-rise properties, Dunning offers direct experience with multi-unit residential and mixed-use buildings alongside retail shops, schools, medical centers, restaurants, and industrial manufacturing facilities. Their industrial division has logged thousands of hours installing and maintaining mechanical electrical applications — including production lines, plant maintenance systems, heating and cooling electrical components, and energy management systems — for some of Chicagoland's largest manufacturers and warehouse operators. Commercial clients benefit from Dunning's underground utility and site lighting capabilities, which the company describes as a specialty, reducing the change-order surprises that plague large-scale projects. The team's estimating staff can receive plans and prints digitally for faster, more accurate bids. Dunning also emphasizes energy efficiency across all service categories, helping facility managers identify cost-reducing electrical products and applications in line with Chicago's sustainability goals. A dedicated emergency line (312-296-6848) provides 24-hour response across the Chicagoland area, a critical capability for facility managers who cannot afford extended downtime. All work is backed by a one-year parts and labor guarantee. The company is licensed, bonded, and insured, maintains OSHA-compliant safety standards, and regularly updates its internal safety manual. For property managers seeking a single contractor capable of spanning office, retail, industrial, healthcare, and multifamily electrical scopes across greater Chicago, Dunning Electrical Services presents a well-tenured option.
