4th Generation Electric Inc.

When a customer's generator sat dead for four months, 4th Generation Electric stepped in and had it running again in two visits — the kind of story that turns up often in reviews for this Leominster, MA electrician. The company's electrician license, number 21205, held by John P Perry, is active on the Massachusetts registry, and the business is also state-verified as a Veteran-Owned Business. By its own account, 4th Generation focuses on Generac standby and portable generator installation, service, and maintenance for homeowners in Massachusetts and southern New Hampshire, alongside broader residential electrical work. Google shows a 4.9-star average from 287 ratings, and HomeAdvisor and Angi both show 5.0 stars on smaller samples. The specifics back it up: whole-house and portable Generac installs handled start to finish, including permits and propane coordination, a 200-amp panel upgrade completed while working with the local utility, and a legacy wiring mistake left by a previous electrician diagnosed and fixed with a clear explanation. One reviewer, waiting on a hard-to-find transfer-switch part for almost a month, said the crew came out and finished the install even in the rain once it arrived, in a review from December 2025. Another needed help with an aging solar array's inverter and said 4th Generation was the only company willing to take it on, in a review from March 2025. Not every account is glowing. A customer in a June 2025 review said they were charged $375 to replace a simple $65 motion light that was already wired, and the replacement light turned out to be defective. Separately, a March 2026 comment — from someone who said they hadn't hired the company — described a company van driving through a residential street in a way that felt unsafe with kids playing nearby. For a generator install, repair, or a stubborn electrical problem another electrician has given up on, 4th Generation has a track record worth calling about. For smaller, simpler jobs, it's worth asking for a clear estimate before work starts.
