Williams Energy

Williams Energy is a Braintree oil-and-HVAC company that a lot of South Shore households have stuck with for a long time — reviewers describe relationships running 10, 20, even 30 years, with a few saying they inherited the account from a parent's household. The thing that keeps showing up in the reviews is speed on a no-heat call: a dead furnace or boiler typically gets a technician out within a few hours, even during a busy stretch. Google shows 4.8★ across 317 ratings, and the written reviews back it with specifics rather than just enthusiasm — technicians named individually (Ian, Gavin, Brian, Jose, and Dylan among them) for walking customers through what broke and how it got fixed. The work described runs past furnace and boiler repair into mini-split and central-air installs, humidifier swaps, and — alongside the heating side — plumbing calls like a water-heater replacement and pipe repairs, plus oil and propane delivery. When a neighbor asked a Nextdoor thread about hiring a boiler installer, the answer that came back was Williams. The written history isn't spotless. A review dated April 2025 alleged a $500 charge for ten minutes of work and said the company ran a card on file without authorization and without quoting a price upfront — worth asking about directly before leaving a card on file. A review from November 2025 described a propane order that slipped its delivery window twice, stretching from days to weeks. An older 2022 review flagged scheduling and support as unhelpful during a service-contract year. Williams reads as the long-tenured, call-now option for a South Shore household already on an oil plan or a service contract.
