Kevin and his work were fantastic! He did a wonderful job with our panel update and mast install. We had him also do some work inside the house which was of the same quality. We will be using his service for future projects.

Work done on time and as agreed. All process was very simple. Definitely good choice and can recommend to others.

Hanco Electric did a fantastic job on the transfer switch for our backup generator. We are prepared for inclement weather leading to outages because of their good work. We’d hire them again in a minute!

Kevin and his team did a wonderful job of replacing the knob and tube throughout our house, in addition to upgrading the breaker box/meter/service. They were very accommodating of us as home renovators, and were happy to absorb additional scope as we unearthed additional problems hidden behind the drywall. We happily recommend them to others with an upgrade project in an older home.

I am woefully ignorant when it comes to electricity, so when we ordered a new electric car I knew I'd need to hire someone I could feel safe with, assured of and trust to do a good job at updating our electrical panel and install an electric car charger. I couldn't have made a better choice than Hanco Electric. They were the perfect combination of prompt, professional, competent and reasonably priced. I will definitely be calling them for any future electrical needs of my own and I would highly recommend them to anyone else in need of electrical services.

Service/Panel Upgrades

 Upgrading your electrical panel is a smart investment in your home. If your panel is older than 50 years, a defunct brand (Zynsco, Federal Pacific, etc), or you have plans for additional loads (electrification), now is the time to plan your upgrade. We offer free estimates and consultations.

Standby Generators

Stay prepared for power outtages. Whether you need to connect a portable generator to keep the lights and refrigerator running, or prefer the convenience of a whole house generator with an automatic transfer switch, we can help you plan for the storm.     

Renovations and Remodels

New kitchen or bathroom plans will likely require relocating and additional circuits. Refrigerators, ranges, dishwashers, disposals and microwaves all need their own circuit. In addition, you need at least (2) 20A circuits to provide power to the countertop receptacles. Contact us for a free quote to help you realize your perfect space.

Commercial Spaces

As your business needs change, allow Hanco Electric to keep your electrical system working for you. Lighting upgrades and retrofits, new circuits, rewires, energy monitoring, and electrical audits are available.


Hot tubs and HVAC equipment require dedicated circuits and disconnects. We follow all electrical codes and manufacturer instructions to insure your installation will be safe and long-lasting.

Licensed and Insured

Don't risk your project and property by hiring unqualified electricians. Ask for credentials, referrals, and a warranty.
