Ask a Power Now customer what they actually bought and most of them describe the same night. The storm rolls through, the street goes dark, and the unit outside picks up the house within seconds. One 2023 reviewer wrote that after a major New England storm took out most of the homes on the street, the generator caught immediately and the kids stayed warm.
This is a whole-house standby generator outfit: sell it, install it, then come back twice a year to keep it running. The owner, Jason Tabasky, is named personally in reviews stretching from 2017 to 2024, usually alongside a small crew — a 2023 Google reviewer described plumbers and an electrician on site for the install, and a 2024 reviewer credited Jason and his staff with inspections every six months.
The volume behind that is real: 58 reviews across seven sites between 2015 and 2024. Google runs 5 stars across 34 ratings. Angi and HomeAdvisor both print 4.9 from 194 ratings — the same base counted twice, since Angi mirrors HomeAdvisor. Thumbtack sits lower at 4.6 from 22. The Better Business Bureau grades the company A+.
What repeats in the write-ups is maintenance rather than the sale. A 2023 reviewer who bought a house with a generator that had not been serviced in nearly a decade said Jason's team brought it back up to par. A 2018 Thumbtack customer described a neglected unit cleaned out, bad gas and oil replaced, the battery swapped, and the machine running before he left. In a 2023 review, another customer said Jason stepped in over a dispute with a propane supplier that had nothing to do with the generator itself.
Two things are worth raising before you call. A 2017 Angi customer rated the company one star, describing a repair that got worse rather than better, a month waiting on ordered parts, a cancelled appointment, and being told outright that the owner does not answer his phone or return email. It is the single dissenting account in a large set, and it is nine years old — but it is specific about communication, and a 2018 HomeAdvisor customer's entire comment was that you have to be prepared to wait. Second, the written record runs 2015 to January 2024 and nothing newer has been posted, so the praise you are reading describes how the business ran two and a half years ago rather than this season.
If you already own a standby generator that has been sitting unloved, this is the kind of shop that record suggests: patient with old units, structured around a maintenance contract, and reachable through the owner. Confirm current scheduling and callback expectations up front, ask who holds the electrical licence for the transfer-switch work, and get the maintenance interval in writing.
