Generac whole home generator

Heritage is an Official Generac Dealer 

The benefit of a whole-home generator is peace of mind of 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 aren’t meant to last longer than a few hours. Plus, many other systems like your heat or cooling simply won’t work when there is 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.

With Heritage Home Service, we make the process of finding the right whole-home generator for your needs as easy as giving us a call.

Our services aren’t limited to whole home generators. Heritage offers a variety of Generac services including portable generators, water pumps, and more!

Whole-Home Generator Services in New Hampshire

Our generator professionals are able to provide installation for whole-home standby generators by Generac, an industry leader in quality and performance. We also repair and service most makes and models of generator equipment, including Kohler, and Briggs and Stratton. Whether you’re looking for a new installation, maintenance, or if your current generator is having trouble, Heritage is here to help.

As we alluded to earlier, even those of us on more reliable power grids experience outages with the unpredictable weather we can experience in New Hampshire. If you have critical systems that need to stay on even when there is an outage such as a sump pump, sewage ejector pump, or maybe have a family member with oxygen dependency. In these situations, even a short power outage could make for a major disruption in your life – not so with a whole-home standby generator.

Depending on the size of your home and the model you choose, a standby generator provides enough power to supply most if not all of your home’s energy needs. By connecting to either a natural or propane gas supply, your standby generator can run for longer periods of time than a portable and automatically turns itself off when power is restored.

Like most comfort equipment in your home, we recommend routine annual maintenance to ensure your generator works for many years and is ready to perform when you need it most. Annual maintenance is usually required to maintain your manufacturer’s warranty as well.

Blackout Ready Portable Generator Bundle

Portable generators are a great option for homeowners who rarely experience power outages, but still want the peace of mind that they are prepared in the event of an emergency.  If you’re looking for a complete portable generator package that gets you from having nothing, to having a reliable backup power source ready to use, this bundle is for you!

NOTE: Unlike our whole-home standby generators, portable generators require you to manually connect and start them each time there is an outage.
