Propane near Groton, CT

“I had a fantastic experience with this company from start to finish. The sales team was very professional and walked me through all my options without any pressure, which made the process smooth and easy. The installation crew was on time, efficient, and did a great job setting everything up. My nee Mitsubishi units are working perfectly, and I couldn’t be happier with how everything turned out. I would highly recommend them to anyone looking for reliable and professional AC service!”

“I first became a customer of Advanced heating oil about 10 years ago. They were the least expensive and had fast service. Then the unexpected happened. I wasn’t paying attention to the tank level, and we ran out of oil. Even though we couldn’t get a delivery for a few days, they sent a driver with 50 gallons so we could have heat and take hot showers while we waited on our delivery. Their kindness meant so much . So when we moved back to CT, I knew I wanted to use Advanced heating oil again. Early this week I did it again. The tank was on E, and a huge snow storm coming. I called for a delivery but it would be a few days wait with the storm and weekend coming . So I did everything I could to reduce the need for the furnace, and oil use and hoped for the best. But this morning I noticed the tank was full. They must have sent someone yesterday, even though I don’t believe they are open on the weekend. This company seems to care about their customers more than most I’ve dealt with in the past, and I’m grateful for their kindness.”

“Called and spoke with Chris because for 3 months running my bill has been incorrect due to wrong budget amount. Last month I spoke with Joan who Said she'd fix the error. Alas the error stayed on the bill. Chris said she fixed it this time and I am hoping it is permanently fixed. DDLC is always helpful and I've been with them for over 30 years. I hope to continue.”
