Why COD heating oil?
COD means you buy oil one delivery at a time. No long-term contract, no automatic deliveries, and no one forcing you to fill the tank.
You decide how many gallons and when — so you stay in control of your budget, and you still get the same quality #2 heating oil a full-service company delivers.

What our customers say
I can’t say enough about this company. They go above and beyond to do the right thing. I buy my heating oil as I need. I ran out today and ordered a refill online. After placing the order I called to see if I could get same day delivery. The women that answered the phone already knew my order and address. She said she could not give me an exact time but insured me that I would get my delivery the same day. As promised I had it before the end of the day. These guys are great. I’ve been a happy customer for almost 10 years and will not go anywhere else. They have competitive prices and delver you order quickly.
I love that I can order oil online. It is incredibly convenient. Thank you for the wonderful service.
I love using this company. Great prices, efficient and timely service. I won’t use anyone else.
Fast deliver thank you! Great customer service
