Client Testimonials

“I would like to share my sincere opinion. I am so happy I found Guerra and Sons Electric a couple years ago - meaning, my assessment is based on repeat performance. Their service is excellent, their staff are friendly, professional, and helpful. They maintain our Generac full-home generator by visiting us twice a year to do a full assessment, check-up on components, and oil change. I feel the quality of the work and scope of what they do, makes their prices very reasonable and fair. If you have a generator, these guys are the real deal.”

“Called multiple people for generator maintenance service in my area none responded I stumbled across this company a little bit outside of my area. They were quick to respond, they actually wanted my business. When the service technician came out he was friendly, knowledgeable and excellent , took care of everything. I like these guys so much I'm going to go on the maintenance plan. Thanks.”
