I have used this company twice. First time to upgrade my electrical panel prior to having new air conditioner/furnace installed. Just very recently to replace housing in ceiling light in a bedroom. They are very professional, punctual, very knowledgeable and friendly, as well. I would definitely recommend them to whomever is in need of electrical work.

I am so pleased with Duffy Electrical’s service. They have been the best business I’ve worked with for ANY of the work I’ve had done on my home, electrical or otherwise. They were exceptionally organized and professional at all times. They came quickly to give me an accurate estimate, Jerry was an absolute delight and both very knowledgeable and practical about the solutions for my individual needs. They’re available by email and sent the written estimate to me quickly. (I love this. Brenda once replied in less than five minutes. I wish more companies were really available by email, it so helps me stay organized while traveling.) They were up front about what could and could not be done as well as what probably wasn’t worthwhile, completed everything when they said they would and to a high standard. They even coordinated with another company doing work on an adjoining system – and worked around their schedule when that company was much more poorly organized. I will absolutely call them for any and all electrical work in the future and highly recommend them.

Frequently Asked Questions

What areas does Duffy Electric serve?

Duffy Electrical Contractors is based at 1260 E 15th St in Tucson and has served Tucson and Southern Arizona since 1969. Our electricians regularly work in the greater Tucson area, Oro Valley, Marana, Vail, Green Valley, Sahuarita, and SaddleBrooke, for both homes and businesses. If you’re not sure whether your location is covered, call us at (520) 624-8617.

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.

How do I schedule service or get an estimate?

Call us at (520) 624-8617, Monday through Friday from 7:30 AM to 4:00 PM. Your call is answered by a real person, never an automated system. You can also reach us through our contact form or at brenda@duffyelectric.com, and we’ll respond within 24 hours, Monday through Friday.
