Order oilDirect from the company
Plymouth Oil Services delivers heating oil and installs boilers, oil tanks and water heaters; on its website the company says it has been locally owned and operated since 1969. A recent customer, a first-time homebuyer, said the company came on the day of closing, before an account was set up, and made sure there was oil in the tank. That customer said it also installed their new boiler and hot water tank. A 2026 customer said that after a blizzard the company rearranged its delivery schedule to make a delivery in the snow. A 2026 customer said Jessica emailed that she was ordering oil for their elderly mother because of the weather. A 2025 customer said the team finished a boiler install in less than one day and came in a couple hundred under budget. A 2025 customer enrolled in the automatic-delivery program said the company adjusted the delivery schedule by monitoring usage. A 2024 customer said Chet and crew installed a new boiler and Roth oil tank and removed the two older appliances in two days, then swept the floor and the basement walls. A 2023 customer said they called multiple times over two years to schedule a furnace cleaning and never got a call back. In a 2023 review, a firm representing a home buyer disputed the company's oil-adjustment invoice at a closing and said the company would not correct it. On Google it holds a 4.9-star average from 121 ratings, and its BBB grade is A+.
Honestly, five stars and what I’m about to say does not do Plymouth oil company justice! Being a first time homebuyer, and never having lived in a home with oil before they made everything such a breeze, were extremely patient And made sure that our house and water was always warm. They also have super convenient payment set ups, Where you can even get a nice little discount… And they keep track of your oil usage so they come before you Even come close to running out without you having to lift a single finger! I will never forget they came the day of closing, even though we had no account set up and made sure that there was oil in the tank so our babies were warm. They also installed our new boiler and hot water tank, it’s quite a set up for The perfect shower where our water is constantly warm, even when our other appliances are running Plymouth oil company has a lifetime fan and customer out of me, I will recommend nowhere else! To put it simply Chet, Jessica, and all their employees are amazing!
I am doing this review for my mom who has had Plymouth Oil for years. She is now elderly. I received an email from Jessica that she was ordering oil for her since they were concerned with the weather that she would run out. They handled everything for me. It is peace of mind for me that they watch out for her. What other oil company does that??? I doubt any that I know of. I am very thankful for their service and care.
Plymouth Oil has helped me many times over the years including consultation and installment of a new oil tank. They are professional and timely. Today after a blizzard they rearranged their delivery schedule in order to accommodate a delivery in the snow. I cleared a path and communicated with the office who helped make the delivery possible. The guys were friendly and did the job quickly no issues. This is a small family owned and operated business doing their best to help people under all circumstances and weather conditions. Highly recommend.
Great customer service
I’m so grateful to have such a reliable and amazing oil company right here in town. Jessica and Chet are absolutely fabulous—knowledgeable, kind, and genuinely caring. Customer service like this is hard to find!
