Verified record
Mansfield Oil & Energy has been delivering heating oil in the Mansfield area since 1961, a company history corroborated independently by its Better Business Bureau file, and describes itself today as a family-owned operation that also installs and repairs home heating and air conditioning equipment. The clearest thread in its reviews is a technician named Keith, credited in a 2022 review from an eight-year customer for repeatedly rescuing an aging, 38-year-old boiler and teaching the homeowner how the system works along the way, coming same-day according to that account. A 2024 review describes a similarly smooth oil delivery, and a 2021 review calls the company reliable with quick delivery over years of use. The one real concern worth knowing before calling: in a January 2024 review, a longtime-area resident says Mansfield Oil refused to service a broken oil burner during a 15-degree cold snap, with a one-year-old at home and no heat, because she wasn't currently a regular oil customer — telling her it wouldn't matter if it was an emergency. That's a specific, serious account of someone being turned away in a genuine emergency, not a vague complaint. Anyone counting on them for emergency heating repair should confirm directly whether service depends on being an active oil customer, especially if oil isn't currently being bought through them. The praise in the record is real, but so is this account.

Great company! we used them for years! Great customer service!
My oil burner stopped working, and I called mansfield oil to see if they could service it. It was going to be 15° and I don’t have any heat plus I am home alone with a one year old. They told me “I didn’t get oil from them for a while so Im not a regular customer and it doesn’t matter if it’s an emergency, they will only service their customers.” I will never get oil from you and I will make sure I tell everyone else not to.
Need oil called Mansfield oil. Seamless transaction. Highly recommend
I've been a customer of Mansfield Oil for 8 years now and I've always been 200% impressed. Keith is one of the most helpful people I know. He has not only come to rescue me from heating issues with my 38 year old boiler several times, he teaches me as he works so I can learn about my house's heating system and take care of future problems before they arise. Keith is an intuitive engineer and takes care of my boiler like it's his own grandma's, even coming the same day when something arises. Five stars! Definitely hire Mansfield Oil.
Been using these folks for years. Reliable, quick delivery when you need it.
