Maria's Oil

Maria's Oil delivers home heating oil and runs its own service department, working on oil and gas heating systems, air conditioning and plumbing. The company says it started as a service department in 1996 and grew into a full-service oil delivery company, and it lists offices in Chelsea and Reading. Google shows a 3.5-star average from 26 ratings. The service side is what customers describe most concretely. In a November 2025 review a homeowner wrote that technicians Jim Sr. and Paul tracked down and replaced the part on a 20-year-old furnace, and that the office staff were pleasant on the phone. A February 2025 customer said that every time they called, the company came out the same day or the next day when weather allowed, and a January 2025 reviewer described quick responses, reasonable prices and helpful staff. The complaints are older but detailed, and they cluster around billing and delivery accuracy rather than workmanship. A February 2023 reviewer wrote that oil their sister had paid for was pumped into another tenant's tank, and that the company's suggested remedies were to buy more oil, ask the neighbour for the money, or buy a pump and move the oil across. An October 2022 customer said a phone quote of $5.25 a gallon was billed at $5.69 when the truck arrived less than 24 hours later, with no advance notice, and still rated the service itself satisfactory. A March 2022 reviewer said they were charged $125 for a problem they traced to the company's own earlier service call, and an October 2021 reviewer said they paid to have a boiler primed, found a receipt on the door with the boiler unprimed, and could not get the company back on the phone. Worth doing before booking: get the per-gallon price and any service charge confirmed in writing at the time of the order, and confirm the delivery address and quantity on the ticket. For furnace and burner work, the recent reports point to a capable service crew.
