"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."

"I bought my unit from NETR in 2018. It worked fine until we discovered it wasn't blowing any cold air. I made the big mistake of hiring someone a family friend recommended and they diagnosed it incorrectly and then basically disappeared on me. Anyway, it took a few weeks but they repaired it today and I was impressed with their courtesy and getting the job done very quickly and successfully. I felt like I was being dealt with honestly. Thanks, Jared and Jack. I should mention I paid about $300 for the refrigerant today. I don't know what the final cost will be but probably a bit over $1000."

FAQs for generator repair projects in Nashua, NH

Always start by confirming the pro’s license number, insurance coverage, and experience level. Visit the electrician’s website, scan recent customer reviews, and verify credentials with your local labor department. Request proof of liability insurance and at least two references that you can contact. These quick checks take only a few minutes but go a long way toward ensuring safe, code-compliant work and protecting your home in the event of an issue.

Grouping several electrical jobs into one appointment means you pay a single service-call fee and one set of travel expenses. Instead of asking a pro to return three separate times for outlets, switches, and fixtures, have everything tackled in one visit. The electrician stays productive, and you avoid extra trip charges, often shaving a sizable chunk off the final bill without compromising quality.

DIY electrical work can be dangerous and, in many areas, illegal without a license. One miswired connection risks shocks, fires, or expensive damage. Licensed electricians carry the right tools, follow local code, and know how to shut down power safely before they start. Hiring a pro may cost more upfront, but it protects your home, family, and insurance coverage in the long run.
