Sterling Oil LLC

Sterling Oil LLC, which shares its website with Bertrand Oil Service, says it has been in business since 2011 with 35 years of heating oil delivery and service experience. Its website names Plainfield, Sterling, Brooklyn and Killingly as its service area. A 2026 customer thanked Bertrand Oil from Moosup after their heat stopped working at 7:30 pm the night before an 18-inch snowstorm: Josh "was here within the hour and got it started back up within 45." A 2025 customer said they had been getting oil from Sterling Oil for seven years, and that after coming home from vacation to a tank close to empty, they called in the morning and the company came the same day. That 2025 customer also said the company cleaned their furnace the previous fall. A 2025 customer wrote that Josh did their annual furnace cleaning and walked them through troubleshooting an electrical issue at 8 pm on a Friday. A 2026 customer said Josh had just installed a new tank for them. A 2023 customer said that when their furnace started leaking, they called on a Sunday night and the company came out on an emergency visit at no charge, then quoted and installed a new furnace; that customer thought the quote was a little high. A 2026 customer said they were never called back and went elsewhere. A recent customer calls the company informative and honest.
