Competitive pricing, no haggle as to what they do - it is straight forward oil delivery. No…read moreservicing of the boiler, no required annual check-up, no contracts and no purchases of oil futures to lock in a price. Everyone pays the current market price listed on the website and give them a call when you want a delivery. Although they try to get you in same-day if you really need oil, they prefer to deliver the next day. We've got dogs, so the driver always calls 10-15 minutes out, which gives us time to bring the dogs in and clear the way for the oil to be delivered. We've never been disappointed with a driver, some are more "friendly" than others, but they all like our dogs and close and lock our gate when finished, which is a lot more than what we experienced with some of the bigger guys out of Newton and Needham.

We have been loyal customers of Jamie Oil for over 9 years. We recently encountered an issue that…read moreleft us without hot water in frigid December. Following a service call, Jamie Oil diagnosed the issue as a hole in our water heater coil, and indicated we needed to replace the hot water heater. They indicated they would send an estimate. After calling them several times to request the estimate, I finally received one 5 days later! That's a long time to wait just for an estimate when without hot water in winter. Ultimately, we went with another company that provided much more professional, polite, and prompt service. It was disappointing that a company we had never worked with was more responsive than a company we've done thousands of dollars of business with over a decade.

The two technicians, Jeff M. and Dave Q, were very competent, knowledgeable, and efficient. The install was done the day after we requested it.

All three gentlemen were courteous and willing/able to answer questions.

Stephen Smith and the team made the process very simple. We had clear communication with their technician while onsite evaluating our options to move the tank. The technician provided good information for us to consider, and in the end, it was an easy decision to upgrade our tank and protect our investment into the basement remodel. It was great to learn there was an option for zero percent financing (pending qualification) which helps, especially around the holidays! We are very happy with the job that was done, Thank you to Stephen and the folks at Devaney!

I tried them originally through their introductory furnace inspection. They came out and inspected…read morethe furnace, and said the furnace was fine but our thermostat was broken and they'd replace it for $300. I told them I would do it myself, and reinstalled the original thermostat, which worked fine. 2 months later (in December) the furnace stopped. I called them, they said they would try to get here that day. We waited all day with no response. They came the day after and said they needed to order a part, but could not tell us when it would arrive. Into the weekend, after 2 full days without heat, they said to get heat on the weekend would cost $1200, or $700 if we waited until Monday or Tuesday. We chucked them and called another company. That company said this was a common problem and should have been caught in the inspection. They could come on the weekend to do it for $1000, or do it on Monday for $500. I shouldn't have called back after the thermostat issue, but I sure won't call again, and recommend anyone else also look elsewhere
