Williams Energy

Williams Energy has been delivering heating oil and propane around Braintree since 1919, by its own telling — the kind of near-century-old, family-run outfit that South Shore homeowners call when the furnace won't start on the coldest night of the year. It describes itself as family-owned and local, and that tracks: what people hire it for is a fuel-delivery-and-repair shop first, not a general remodeling contractor. The last six months are where this gets specific. In June, a two-decade customer described round-the-clock response and technicians who pinpoint the problem before pricing the job on the spot. In late February, a homeowner wintering in Florida had their Braintree oil drum run dry during the coldest weekend of the year, and Gavin's crew got the heat back on. In January, someone had a 50-year-old boiler and oil tank replaced with an Energy Kinetics unit and a double-walled tank, and pointed to the crew's communication and cleanup. Office staff come up almost as often as the trucks — Ann Marie rescheduled an air-conditioning visit around a customer's travel plans, and Kelly drew a specific callout for being helpful and responsive. None of the eleven reviews from this stretch are negative. That lines up with a much longer track record: 110 reviews reaching back to 2021 across five sources, plus a 4.8-star Google average from 317 ratings and similar 4.7–4.9 averages on other directories. Both the volume and the years point the same way. It isn't spotless. An older review describes a multi-week wait for a propane delivery, and a separate site carries a review saying years of good service went downhill for a stretch before that customer switched providers. Neither is recent, but they're real, and worth asking about if delivery timing or scheduling matters to you — especially during a cold snap, when a delay actually bites. Plumbing and electrical jobs show up too — a home rewire and plumbing update after a purchase, a same-day plumbing repair — but they sit alongside the main business: oil and propane delivery plus the boilers, furnaces, and heat pumps attached to it. If you're on delivered fuel on the South Shore and want one company for both the tank and the equipment it feeds, this is the profile to expect. Before booking, it's worth asking about current delivery lead times given the complaint above, and confirming your town falls inside the Braintree-centered service area Williams lists.
