TL;DR- One star for business ethics - Oil spilled on property. Decent price, called the owner a few times and he sounded friendly. However, for the past few oil deliveries, they constantly spilled diesel on my walk path. When it first happened, I didn't notice until the next day after delivery and saw my dog was licking his paw like crazy after our walk and this awful diesel smell on him. Took a good hour or two to clean my dog and the concrete. I first thought it was an honest mistake until it reoccurred the next month after auto oil delivery. Never received any notes from them admitting it or saw attempts of cleaning up their own mess- Like it ain't hard to grab an oil absorption pad while taking that nozzle from the truck to the fill pipe and reverse. Now, after snow just melted, all the diesel they spilled into the soil and sidewalk can be seen running off down the street into the sewage drain. EPA? OSHA? Never heard of them.

I chose Thermoil for an installation through the Mass Save rebate program and had a great experience. The technicians were professional, always on time, and kept everything extremely neat and clean. Anytime I had a question, they took the time to explain things clearly and made the process easy to understand. They stayed on schedule from start to finish, which made the project smooth and stress-free. My wife works from home, and the team was very respectful and kept noise to a minimum so she could continue working without interruption. Overall, an excellent experience and definitely a five-star company. The office staff was also fantastic and very helpful with the loan process and paperwork.
