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.
