4th Generation Electric Inc.

4th Generation Electric Inc. is an electrical contractor based in Leominster, serving homeowners across the city and nearby communities including Groton, Littleton, Acton, and Carlisle in Massachusetts, along with southern New Hampshire. The business maintains standard hours Monday through Saturday from 8 AM to 4 PM, is fully insured, and offers free estimates. Holding Massachusetts license 21205-A and New Hampshire license 13466M, the contractor operates as a veteran-owned business.

What sets this contractor apart is their specialization as Generac Authorized Dealers, focusing exclusively on generator sales, installation, service, and maintenance for both whole-home standby units and portable models. This narrow focus allows them to deliver what multiple reviewers describe as turnkey installations where every detail is managed from start to finish. They back their work with a free five-year warranty valued at $535 on qualifying purchases and offer 0% interest financing for 18 months.

Reviewers consistently describe specific technicians by name, including John who arrived as scheduled to handle a liquid cooled generator and provided honest, upfront answers to all questions with knowledgeable explanations. Another reviewer detailed how their team worked through rain to install a transfer switch replacement on an older Generac unit, arriving prepared despite weather challenges. Multiple reviews praise clear communication through texts, emails, and phone calls.
