This review is for oil to gas conversion and Jeff has a wealth of knowledge from getting gas meter setup, inspection, and boiler and water heater installation. He and his entire team were very professional and hardworking and I am very happy with the service I received. Work was done as scheduled even when there was some minor hiccups during the process and they gave me a peace of mind and they handled and coordinated everything from start to end and I didn't have to look back nor worry.Sandy excelled with communication and any questions I had were answered in a timely manner and received the top notch customer service and the great thing about this company is that their response rate is unbelievably fast and they were able to fit me in their busy schedule and they were able to give me a schedule within a month, and I am now well ahead and prepared for winter. Thank you again for all of your hard work, transparency, and quality service you had provided. I highly recommend this company.

He explained how they would design and install the new furnace and all the zones. He obtained new hot water heater at no additional cost as well as the available rebates. The actual installation was accomplished in one and a half days. Everything was done very professionally and the area left totally clean. He

Absolutely great crew,worked very hard and left everything cleaner than when they got here. I would highly recommend them to anyone who needs a heating service. Also, the young men working there were very polite, something you don't find often in this day and age.

The quality of the workmanship, and the attention to detail is second to none. I contracted J Griffin to replace my old oil heating system and install an energy efficient gas boiler. Jeff and his crew handled everything. They removed all the old equipment, (including the oil tank), installed the new system, cleaned up everything, and they were finished in a day and a half.
