My family has been using Cain oil for over 30 years. I just recently bought my first home and my entire heating system needed to be replaced. John was knowledgeable and helped me through the process of picking the right unit. His prices were reasonable and work was done within 24 hours. I would highly recommend their services.

Cain Oil is a LIFESAVER!!!After being stood up for our scheduled service (a different provider in Somerville, who No showed two different times) I reached out to Cain Oil after being referred by a friend. John sent out two service team members within 30 minutes and our heating unit was up and running in no time! They were professional and extremely knowledgeable. I am so grateful for the timely service and attention to detail. Highly recommend!

We have used Cain for oil delivery and maintaining our heating system for many years. But this summer our air conditioning broke and they were able to fix it quickly for us. Its great that they do both heating and cooling.

John and his team do a phenomenal job. Great group of people. They are reliable, knowledgeable, friendly and work hard as they do the job right. Very dependable company and great to work with!

To john and his entire staff.. best service and on time everytime for anything we need day or nigjt.. highly recommended company

We got a new heating system installed as well as central air by Cain Oil and could not be happier. Our heating bills have decreased and the central air installation was the best decision we made! Oil delivery is dependable and the customer service is excellent. Thank you Cain Oil!

John and his entire staff are very friendly, honest and reliable people! I use them for oil delivery and all my plumbing needs! Highly recommended!

They trek up my hill every time and even in the snow. They installed a heating system and it works great. Very dependable company.

They are great!! Fast, friendly and reliable!! Totally recommend them!

Our furnace broke down on the coldest night of the year, Cain oil responded and had me up and running very quickly. I plan to have them replace my furnace and hot water heater in the spring!
