Heritage is Your Official Generac Dealer in Massachusetts

Even on a stable power grid, you should plan for power outages when living in the Northeast. Our unpredictable weather means outages are common and can last a few hours to days.

Standby generators engage when an outage occurs and automatically shut off when power is restored. Many families are turning to whole-home standby generators as an alternative to small battery backups and portable solutions.

Whether researching your options or looking for service on an existing generator, Heritage Home Service’s Generac generator experts are here to help.

In addition to standby generators, Heritage offers a variety of Generac services including portable generators, water pumps, and more!

Jake was professionally friendly, clear with his assessment and generous with his time giving me the overview. After 3 plumbers couldn’t fix the issue he was efficient and thorough. He also struck me as well read, articulate and Heritage is lucky to have this professional on the team. Ive already recommended Heritage to my client for plumber services. Elated sums up my experience. Thank you DebSmith Weare NH

Frequently Asked Questions

  • Why should I install a whole-house generator at my Massachusetts home?

    Massachusetts experiences severe weather including nor’easters, ice storms, and hurricanes that can cause extended power outages. A whole-house generator automatically restores power within seconds of an outage, keeping your heating system, sump pump, refrigerator, and other essentials running safely.

  • What size generator do I need for my home?

    The right generator size depends on your home’s square footage, the number of appliances and systems you want to power, and your electrical panel capacity. Heritage provides a free in-home assessment to calculate your load requirements and recommend the ideal generator size for your needs.

  • How does a standby generator work during a power outage?

    A standby generator is permanently installed outside your home and connected to your electrical panel and a fuel source such as natural gas or propane. When it detects a power loss, an automatic transfer switch activates the generator within seconds — no manual intervention required.

  • Does Heritage handle generator maintenance in Massachusetts?

    Yes, Heritage offers comprehensive generator maintenance services to keep your unit running reliably year-round. Regular maintenance includes oil and filter changes, battery checks, and load testing, which are essential to ensure your generator performs when you need it most.

  • Do I need a permit to install a generator in Massachusetts?

    Yes, most Massachusetts municipalities require both electrical and building permits for standby generator installations. Heritage handles the entire permitting process and ensures your installation meets all local codes and regulations so you don’t have to worry about compliance.
