A home standby generator protects your home automatically. It runs on natural gas or liquid propane and sits outside just like a central air conditioning unit. When the power goes out, the generator senses the loss of power and activates, providing power to your home.  Once power is restored, the generator automatically shuts off and your home switches back to utility power.

We provide a variety of home generator solutions to meet your specific needs including servicing of common generator brands like Generac, Kohler, Briggs & Stratton, and General Electric (GE).

Love these folks. First contacted them when our whole house generator hadn’t run for a few years and another company wasn’t able to get it running. Called New Hampshire generator and the owner answered the phone. After asking me two questions he knew the solution and sent a tech out that week. Adam, the technician, was awesome and had it up and running in less than 2 hours (on a brutally cold day). The owner’s diagnosis was dead on and Adam also found another problem that needed to be fixed. Since then, they have performed yearly maintenance on our generator and their technicians are always awesome and very helpful with any questions I have.

We couldn’t have been more pleased with the performance of our unit

Our thanks to NH Generator Installers, and in particular Pete, Bill, and the other members of the installation team, for providing us with a top-notch, reliable solution to power outages in this rural town that is subject to them. Without our sump pump running, we would have had roughly a foot of water in our basement after 2 1/2 days.

This is a great company that answers their phones and takes care of their customers

I called Bill the owner at 6:00 am on Monday the pre-Christmas flood. It was obviously going to be a tumultuous day in this business since so many people had no power. There was a simple issue with my Kohler generator that was quickly squared away by Bill whereby restoring power to my family. This is a great company that answers their phones and takes care of their customers.

We would give 10 stars if we could!

On the day of installation, they arrived as scheduled, brought along the new generator, wiring and accessories and everything needed to effect the installation. Bill and his electrician team acquired the required permits and neatly, efficiently and professionally installed our new generator in two days including a final inspection. The crew assigned were so professional, knowledgeable and friendly and we couldn’t have asked for a nicer job. Click here to read the full testimonial “We would give 10 stars if we could!”

I highly recommend this team!

This is a great company! I bought a house 6 years ago that had a Kohler Generator installed by these guys. They call me every year to service it and this time I needed some repair and a new battery. Always nice and polite, do what they say, and their prices are always reasonable. I highly recommend this team! Click here to read the full testimonial “I highly recommend this team!”

I strongly recommend NH Generator!!

These guys are amazing! Due to an issue beyond their control, after a year or so one of their 2 installations at my location simply failed. Furthermore, the manufacturer was unable to remedy the warranted product. NH Generator worked with the manufacturer to find a solution nonetheless – involving a completely new installation and removal of the old product with zero cost to me. Bottom line: these guys have a great sense of responsibility for the quality and effectiveness of their work. In my experience, companies like this are truly rare. I strongly recommend NH Generator!!
