Hartmann Electric Company

What Hartmann Electric Company does

Hartmann Electric Company is a privately held, family-owned specialty electrical contractor founded in 1990 and headquartered in Elk Grove Village, Illinois. The firm provides design/build, new construction, and maintenance electrical services across seven verticals — aviation, baggage handling systems, data center, industrial, retail, fueling, and low voltage systems — with additional EV charging and renewable energy capabilities added in 2021. Its core technical scope spans voice/data/fiber optic cabling, backup power distribution (generators, turbines, battery plants, UPS), automatic transfer switching, hazardous-location electrical work, and building automation systems, delivered by a team that includes multiple professional engineers on staff.

The business was originally built around airlines and airline-support industries at Chicago O'Hare International Airport, and the firm remains the "preferred electrical contractor" for the largest electric utility in Illinois and a go-to specialist at both ORD and Midway airports. Go-to-market is enterprise field sales via direct engagement with facility managers, general contractors, and property owners; revenue is primarily project-based (one-time) with a recurring maintenance agreement overlay for mission-critical facilities and professional services for troubleshooting and root cause analysis. Marketing relies on a professional website, LinkedIn and Facebook presence, and earned media such as industry publication features, with the bulk of demand generated by 35 years of embedded relationships in the ChicagoLand market.

The firm's go-to-market is regional and concentrated: it explicitly serves only the ChicagoLand area (ORD, MDW, and broader Illinois), with no disclosed geographic expansion beyond that single metro. It is privately held with no external investors or parent company identified, and the Hartmann family (William, John, and Bill Hartmann) remains actively involved in management. Certifications relevant to the EV and energy efficiency verticals — ICC Energy Efficiency Installer, EVITP Approved Contractor, and Chargepoint — have been secured to support the newer service line, while the legacy business is anchored by an EMR well below industry standards and a documented track record of over $100 million in completed baggage handling system electrical projects.
