  • Which Generator is Right for Your New Hampshire Home?

    At Heritage, we’re aware of the power challenges residents face in New Hampshire, where the unpredictability of its weather matches the beauty of the landscape. Our tailored generator solutions, from portable units for the essentials to comprehensive, automated standby generators, ensure your home remains a haven during power disruptions. Let our experts guide you in selecting and installing the perfect generator so you can weather New Hampshire’s storms with confidence and comfort.

  • Heritage is Your Official Generac Dealer in New Hampshire

    The benefit of a whole-home generator is peace of mind, knowing that your electricity won’t skip a beat when there is an outage. It’s about more than just keeping the lights on. Some critical comfort and life systems can get by with battery backups, but they’re only meant to last up to a few hours.

    Many other systems, like your heat or cooling system, won’t work during an outage. This is why many of our customers rely on a whole-home standby generator to keep them safe and comfortable, no matter what the weather has in store for them.

    Heritage Home Service makes finding the right Generac whole-home generator for your needs as easy as calling us.

    In addition to standby generators, Heritage offers a variety of Generac products including portable generators, transfer switches, and more!

    Do You Need a Whole Home Generator?

    Even reliable power grids can falter in New Hampshire’s unpredictable weather, leaving essential home systems and medical equipment at risk during outages. A whole-home standby generator is a safeguard, ensuring that sump pumps, sewage ejectors, and life-supporting devices remain operational, minimizing disruptions in your life.

    A properly sized standby generator, fueled by natural gas or propane, can meet most, if not all, of your home’s energy needs. It offers sustained operation over portable models and shuts off automatically once power is restored, providing convenience and peace of mind.

    What Fuels Can Generators Use?

    Generators, including Generac whole-home generators, primarily utilize natural gas or liquid propane fuel for operation. This flexibility allows for a choice between the two based on availability and preference in various installations. The fuel type – ranging from gasoline, diesel, and propane to natural gas – is critical in determining how long a generator can run. Natural gas and liquid propane are among the four main fuel sources for generators, each with its advantages regarding availability, cost, and environmental impact.

    How Often Does a Whole Home Generator Need Maintenance?

    Like your home’s heating or cooling system, your generator needs a yearly maintenance to stay in peak condition. Think of it as its annual gym membership, keeping it fit and ready to act exactly when you need it. Sticking to these yearly check-ups is a must to keep your warranty in fighting form and ensure you’re comfortable in your home.

I called Heritage Home Service in a panic thinking my house was about to burn down. I called them after the first company I called told me it would be two weeks for them to come out. The woman who answered the phone was very nice and helped settle my nerves. She made it a point to say she’d put me on “early arrival” to get someone out quickly. About 20 minutes later, David was on his way. David was very friendly and professional and most importantly made me feel like I wasn’t crazy for calling them over a fishy smell on my basement stairs. He did a thorough safety check for me and figured out what the problem was. It was fully explained to me and he replaced our melting water heater breaker and enclosure. I had mentioned before the check that the baseboards in our basement weren’t working and maybe that had something to do with it, so he looked at those as well and fixed that too! David was very courteous, going out of his way to make his arrival less noisy, as I had a sleeping baby upstairs. He was fast, efficient and kind and I’d recommend him and Heritage to anyone!
