"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."

"They came out in the middle of a storm and promptly hooked the generator to my panel. While I thought I’d be running extension cords to my appliances it turned out that the whole house was up and running. I wish I had done this earlier. I would recommend MGT for any electrical needs. I will surely use them again."
