"Ted and Robert arrived, got right t to it and within a few hours we had 2 ceiling fans installed, one which had no existing light so it was a more involved project. They were professional and stuck to their original quote! To say we are impressed is an understatement. We strongly recommend using Connole Electric."

"I have used Supreme Electric for a variety of electrical services for over 2 years â replacing outlets to support new wall A/C units, replacing a damaged outlet, replacing a light fixture, upgrading my circuit panel and most recently installing a bathroom ventilation fan another electrician said could not be done. I was also provided assistance finding a carpenter to vent the fan out of my attic and I am considering future installation of a generator. Michael is always pleasant, professional and respectful and the quality of work is excellent. He explains exactly what is needed, prices are reasonable, he communicates clearly and promptly as work is being planned and he is always on time for scheduled work. I highly recommend Supreme Electric. It is always a pleasure to work with Michael and I personally will only be using Supreme Electric for any future electrical work I need to have done. Thank you Michael!!"
