"Matt Sanford and the team at Generator Supercenter were professional, knowledgeable and efficient when surveying my property. They spent quality time educating me on their generator product line and monitoring services. If you're looking for a superior product, company, and team to support you throughout our long New England winters, look no further!"

"These guys came out and worked in the dead of cold in the winter in an old barn and got the job done. It was a good value for the price point. They aren't the cheapest but you wouldn't want that with a professional electrician. John has a good crew of people working with him and they'll get the job done. This was a 100 amp to 200 amp upgrade with a sub panel and electric car charger install."

"I want to thank the staff at the Stratham NH location. As a new customer, we got off to a bad start with a scheduling misunderstanding. After my earlier review, I want to acknowledge that they reached out to me to turn a negative experience into a positive one. It's nice to know that this company cares about their customers. I am very happy with the service they performed on my recent Generac generator. The customer service department and the technician were very professional and courteous. I would recommend this company for your generator needs."

"Emilio was quiet at first but I soon realized he was concentrating on diagnosing issues with my generator. He thoroughly went thru the system and then went about doing the repairs needed all the while being a personable and respectful person. Absolutely would recommend the company again"

"Evan returned my call promptly, we made an appointment, and he kept it. The problem was solar panels and a connection that was broken. Evan found it quickly, corrected the problem within an hour and cleared off the solar panels which had gotten gritty over time. We recommend him!"

"I hired Bill to change a 15amp outlet to a 20amp. The job was more in depth than I anticipated because of the distance from circuit breaker to outlet location and the need for new wiring. We discussed discussed other location possibilities, but Bill was confident he could complete the job as I had planned. He did so with absolute confidence and professionalism. Much appreciated!"
