Some might say we’re meticulous experts in heating oil, cooling, and energy. Or, maybe that we’re neat, dedicated, and very friendly. We may be all of the above, but one thing has remained certain for over 60 years: Peterson Oil Service is the most reliable choice for your family’s comfort, no matter the season.  Our story began in the heart of Worcester, MA and we stay true to our values to this day. Our employees live, socialize, and raise their kids where our customers do. Our entire team delivers the kind of locally minded, attentive service that’s often hard to come by.  And our story continues with the principles we practice. We believe in making the fuels we deliver more efficient and environmentally friendly.  That’s why we deliver Bioheat® heating oil, a blend of biodiesel (a renewable fuel made from organic materials) with conventional heating oil

We at Peterson Oil Service take two things very seriously: your comfort and our success. That’s why our team is made of only expert technicians, installers and designers who are highly trained. We partner with best-in-class companies that manufacture the latest and most dependable high-efficiency equipment to keep you comfortable all year round.
