About
Serving Tucson commercial and industrial clients since 1969, Duffy Electrical Contractors brings over five decades of licensed electrical contracting experience to property managers, facility managers, and general contractors across Southern Arizona — including Oro Valley, Marana, Green Valley, and Sahuarita. The firm holds dual ROC licenses (C-11 commercial and R-11 residential) and is positioned to handle the full scope of commercial electrical work that keeps buildings operational and code-compliant. For facility managers overseeing office buildings, retail centers, warehouses, and institutional properties, Duffy offers tenant improvement electrical work including design-build delivery, service entrance upgrades, and circuit additions — critical capabilities when reconfiguring space for new tenants or expanding operational capacity. Industrial and institutional clients benefit from in-plant maintenance, transformer work, service section installations, and infrared thermographic testing, which helps identify failing connections and overloaded circuits before they cause costly downtime. The team also performs professional panel circuit mapping, an often-overlooked service that brings order to unlabeled or inaccurately documented panelboards — a real-world advantage during emergency troubleshooting or building audits. On the power quality side, Duffy installs whole-facility surge protection and uninterruptible power systems (UPS), protecting sensitive electronics and critical loads in office and mixed-use environments. Commercial lighting retrofits to LED and integration of lighting control systems help property owners reduce energy costs and meet sustainability benchmarks. EV charging station installation — including Level 1, Level 2, and DC fast charger circuits — positions commercial properties to meet growing tenant and employee demand for workplace charging infrastructure. Emergency generator installation rounds out the firm's backup power capabilities. A testimonial from U-Haul of Southern Arizona confirms the contractor's track record with multi-location commercial operators in the Tucson market.
