"Garafano Electric has being taking care of all the electrical needs and upgrades in our 90 plus year old house for a few years now. They always do A+ work. We're currently in the middle of some home renovations and they've been willing and able to work with our erratic schedule. Honest, dependable, and great at what they do. Can't recommend them high enough!"

"My experience with Zero Electric was great! James was extremely knowledgeable about home generators and walked us through several pricing options that fit our budget. Their work was clean and efficient and I will definitely be hiring him in the future for our electrical issues."

"The electricians installed two outlets and one LED light fixture in a very professional manner. They provided good advice and suggested that I consider rejunvenating my electrical panel as my home is now 26 years old without pressuring me to have it done immediately. I will definitely consider Trout Electric when I decide to have it done."

"Ricardo is the best electrician I?ve ever hired. Was very professional and friendly to talk to. Honest pricing for a meter panel upgrade. Did what he said he was going to. Also checked out some lighting fixtures I wanted to get installed in my home as I?ve had several quotes and they were just outrageously priced but he gave me the best price out of 6 electricians! Will definitely hire Rick for all my future electrical needs!!"
