Blackwell Energy Corporation

Blackwell Energy Corporation delivers propane and home heating oil out of Hanover, along with ductless mini-split installation, and calls itself a family- and veteran-owned outfit covering dozens of South Shore towns. Owner Dennis Blackwell has run it for more than 18 years, after earlier stops at Hometown Propane, Choose Energy and AmeriGas — a tenure that lines up with the "Year Established 2009" on the company's own About page, not the "founded in 2019" line on its homepage. In 2025 reviews, customers wrote about being taken care of on the small things. One needed a generator and got a callback right away, then an install on the exact day promised. Others, writing about oil and propane deliveries that same year, described a team that listens on the phone and follows through; one customer whose old stove was replaced said the crew walked them through every switch and cleaned up before leaving. All five written reviews on file are five stars and date to 2025, though Google's overall average sits lower, at 3.7 from 15 ratings — a gap that suggests some unwritten star ratings pull the number down. Before booking, it's worth clarifying which year the company actually traces its start to, since its own materials give two different answers and nothing outside the company confirms either one. The company also says its technicians hold an LP-gas contractor license, a Massachusetts Master Gas Fitter license and a journeyman license, though none of that has been checked against the state registry here. For a straightforward propane or oil delivery, or a mini-split installed on the day they say they'll show up, Blackwell looks like a reasonable call — just ask about the license numbers, and don't be thrown by the lower Google average next to the five-star reviews on file.
