  • 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.

  • Introducing the FLEET Membership

Tech was great! $1140 seems a little steep for two shut off replacements and a faucet install 1.5hrs total labor…but I guess you get what you pay for, and Zach was great.

John came out to fix a faulty dryer outlet and did a great job. He clearly knows his work. He found the problem quickly and fixed it right the first time. What I appreciated most was how well he explained everything: what caused the issue, how he fixed it, and what to watch for going forward. He answered all my questions patiently and never made me feel rushed. The price was a bit on the higher side, but the quality of the work and the peace of mind made it worth it. I’d definitely call him again and recommend him to anyone needing electrical work.
