Generator Supercenter of New Hampshire

On time , very professional, my team of installers came in and did a awesome job considering all the snow they had to remove I am highly impressed, great job men and thank you , Joe

Had 22kw generator, level 2 EV charger and whole house surge protector installed. Got four quotes and not only was Generator Supercenter of NH the cheapest they were the only ones willing to dig the lines and hook up to the propane tank. Weather was horrible, ground was frozen and the team did a great job. Very quick and thorough responses to questions. Would highly recommend.

I highly recommend the Generator Supercenter in Stratham, NH. We recently selected the Supercenter to install a Generac at our location; a location that due to local codes, presented a variety of unique problems regarding equipment location. Through endless patience by their rep”Casey,” the problems were solved to our complete satisfaction. Casey then prepared a very attractive, competitive quote, which we quickly accepted. The installation crew arrived on time, were professional, were tidy, and very friendly; a pleasure to deal with. I also wish to bring attention to “Jack,” the master electrician who installed a new electrical panel for us. Jack was very knowledgeable solving a variety of historical electrical and vexing problems we had ( e.g., out of date, malfunctioning trippers). He did a masterful job. To conclude, I highly recommend the Stratham Supercenter for all of your generator needs. They’re the best!

Had a great experience with our generator installation! On time, good communications, quick response to possible trouble spots! (and our changing of possible sites). Alex did a great job trenching, install, follow up and finishing, like putting the lawn back together! Would highly recommend them for your generator installation!

Generator supercenter did an amazing job from start to finish. Service upgrade, panel upgrade and generator installed on the same day. 100% turn key as advertised, all in house electricians and gas fitters. Highly recommend this company when deciding to get a standby generator!

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!

Wonderfull company to do business with. Professional installation and professional installers. You can't go wrong highly recommend!!

Highly recommend!! In 16 years, we have never had a need for a generator. We were told we were on the hospital grid. Well, apparently, those grids change. Over the last year, we have had too many electrical problems with long outages leading us to come to the decision that it would be prudent for us to buy a generator. After doing the research and seeing all the details involved with ordering, preparation, installation, etc, we decided there are too many important details and decided to look for someone to do everything for us. It's incredibly important to know that we came to this decision in December, 2020 (height of generator demand), during a pandemic and during a time of an extreme nationwide generator shortage. While researching, we saw so many people waiting months for a generator from other companies, trying to do everything themselves, waiting for the transfer switch, then an electrician and so on. We figured we would be lucky to have it for next winter. We met with Matt Sanford, he went over everything in detail, looked at the potential sites for the generator and the propane tanks, measured, etc. He could have sold us a bigger generator, but he thought it would be a waste for us to spend extra money on a specific generator I "assumed" we needed. Matt determined the size needed, made recommendations and we, happily, gave him a down payment check. He said 4-6 weeks. I still had my doubts, but here I am writing a review 4 weeks later, because the installation is complete. It is a two-day process. The workers who installed it showed up shortly before the expected time with masks on, were clear and concise, informative, professional and were very courteous of their surroundings including inside the house. In all honesty, I was floored with their demeanor. They completely took me by surprise and it was well above my expectations. When they called to book the installation, I was told the electricity "could be" out for several hours. We planned for several hours. When they arrived, they said it would be an hour or two. It was out for 15 minutes. They do as much as they can in advance so the power is out for as little time as possible, but there can be issues. DO NOT plan that your power would be out for that short period of time. Plan for the worst and hope for the best. The next person, who installs the gas portion, arrived bright and early the next day. He was just as nice, informative and professional as the workers the day before. The communication from the company is stellar. The people they have working for them are fantastic. I cannot say enough good about our entire experience. You WILL NOT be disappointed. By the way, here's something I didn't even know existed until Matt told me about it. Ask about the house surge protector. Even my insurance company had never heard of it. I wish I had known about it when it came out. Also, based on the work involved with the generator, it is comforting to know we are paying them for maintenance, monitoring, etc. In my opinion, this is a complicated machine to install and maintain. They see everything our generator is doing and if something is not right, they'll send someone out before we even know something is "not right". You don't want to be caught in a major outage and have a failing system. You go through the big expense of buying it and installing it, make sure it's taken care of on a regular basis by a professional just like your car, home heating system, etc. I highly recommend this company.

They are a great team to do business with from sales to tech's. Cant be beat.

Exceptional installation and logistics handling . The team was awesome and respectful.

Everyone should buy a generator from the Generator Supercenter of NH. Everything was seamless, from the sales visit to the installation. Their professional crews exceeded all expectations. I would highly recommend them.
