Is Duffy Electric licensed, bonded, and insured?
Yes. Duffy Electrical Contractors is licensed, bonded, and insured. We hold two Arizona Registrar of Contractors licenses: ROC 070406 (C-11, commercial electrical) and ROC 245941 (R-11, residential electrical).
Can you install an EV charger at my home or business?
Yes. We handle all aspects of electric vehicle charger installation, including Level 1, Level 2, and fast charger circuits. For businesses, we also install parking lot EV chargers. Some installations require a service increase or a new dedicated circuit, and we can assess that during your consultation.
What is electrical panel circuit mapping, and why do I need it?
Circuit mapping identifies exactly which breaker controls each receptacle, light, and appliance in your home or building. Many panel directories are handwritten and inaccurate, which makes repairs and emergencies harder to manage. We map your panel completely, provide a professionally typed directory, and perform thermal testing on all circuit breakers and connections.
