Generator installation in New Hampshire.

It depends on what you want running during an outage. A well-chosen essential-circuit system covers heat, the well pump, the refrigerator, and enough lighting to live normally, while a whole-home system carries air conditioning, a range, and a hot tub as well. We size the unit from your square footage, your heating system, and the loads you tell us matter, then confirm the calculation against the panel before we quote anything.

Both keep generator power and utility power from ever meeting, which is the safety problem any hookup has to solve. A transfer switch is a separate piece of equipment that moves selected circuits over, and an automatic one does it without anyone present. An interlock kit is a sliding plate on your existing panel that makes it physically impossible to close the generator breaker and the main breaker at once. The interlock costs less and gives you the whole panel to choose from, but every step is manual.

Yes, and it is a large part of what we do around Lake Winnipesaukee and Squam Lake. A house that sits empty through a January outage is the case a standby system is actually built for: it keeps the heat on and the pipes intact whether or not anyone is in the state. Standby units self-test on a schedule and report their own faults, so the system is not depending on someone being there to notice.

We are certified to install Generac air-cooled and liquid-cooled systems and KOHLER air-cooled systems, which includes performing the startup and filing the warranty registration so your coverage begins correctly. For portable hookups the generator is usually yours already, and the inlet, interlock, or transfer switch we install works with any make.

Yes. We take on annual service, load testing, and repairs for standby generators regardless of who installed them. Call or text 603-619-8875 with the brand and model and we will tell you plainly whether it is worth servicing or worth replacing.
