  • 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

    As part of doing all we can to extend your peace of mind, we’d like to introduce FLEET.

What Our Customers Are Saying

When my AC quit suddenly, Heritage came in a timely fashion and did an excellent job. The four gentlemen who helped me were professional and knowledgeable. Joe diagnosed the problem and was very thorough in explaining the cost of repair versus replacement. Bobby, Harrison and the electrician Liam did the replacement and were wonderful to work with. They explained the process carefully, answered all my questions and completed the job efficiently and quickly. I would certainly call the company again for any HVAC, plumbing or electrical needs. Thanks Heritage!

First time using Heritage, as two other plumbers I’ve used in the past gave me long lead times. Heritage answered my call personally, and scheduled me same day-amazing considering it was a Saturday! I had a leaking outdoor spigot, and given the drought, waiting a week to fix it was out of the question. The technician sent out, James Shallow, could not have been more professional, knowledgeable and personable. He showed up on time, did the job seamlessly and without issue. He spent time educating us as to how to avoid this problem in the future, and it was a genuinely pleasant experience. I will most definitely use & recommend Heritage again (request Jimmy).

Alex came to fix a water main leak at my home which was pre-manufactured in the late eighties. He found and fixed the leak quickly. After the job was complete I spoke with him about the cause because this is the third time in a year with a leak. He spent the time with me explaining the material used for piping in my place and checked the water pressure. The pressure was on the high end and we both concluded between pressure spikes and old plastic pipes. I asked for an estimate to replace all the pipes. He was able to give me an estimate on the spot and found financing with very reasonable terms. Two days later Heritage Home Services was here with two trucks and completely changed out the piping in a day. In short. This place answers the phone. Gets technician on the job quickly. Great knowledge. Cleaned thoroughly before leaving.

We called several plumbers and I got “we are too busy” and “it’s too small of a job”. Not with heritage though! They were able to get us on the schedule in a timely manner and helped us with our plumbing issue. Thank you Zach! Zach was quick and professional! Will definitely use again!

I’ve dealt with Heritage for many years because of their dependability. They are not the cheapest, for sure, but if you need a plumbing or HVAC system installed or serviced/repaired, there’s none better. I needed repairs to be done on slim duct covers that were damaged after having siding installed on my home. I called Heritage because they were the company that installed the original mini-split system in my house several years earlier. John Lindonen and another technician (unfortunately, I don’t remember his name) showed up as committed and did the repair work. They were very thorough, explaining every issue to me and answered all of my questions. They were polite, and extremely knowledgeable. I wouldn’t hesitate to recommend these guys to my family or friends.

The AI interactive was ok but screwed up my ph# so never got a call. However, Camile arrived and spent time discussing my points and activities performed, helped me tremendously and ultimately didn’t need service. He was professional, informative, and transparent so Heritage, please acknowledge his great service!

Derek Clark from Heritage Home Services did a fantastic job for us. He installed a new garbage disposal and fixed a leaky bathroom faucet quickly and efficiently. He was professional, knowledgeable, and pleasant to have in our home. He took the time to explain everything, completed the work with care, and left the area clean when he was finished. We really appreciated his friendly attitude and excellent service. We’d definitely recommend Derek and Heritage Home Services to anyone looking for a reliable plumber!
