Darien Homeowner’s Guide to Selecting an Oil Company
For Darien families heating with number two heating oil, selecting which of the 35 heating oil companies that serve Darien plays a big role in determining how much money is spent on heating each winter.
Full Service Oil Companies: Homeowners who prefer a “set-it-and-forget-it” heating system choose one of the 21 “full-service” oil companies that serve Darien. Full service companies such as Montanari Fuel Service Inc or Rural Energy LLC offer families annual contracts which consist of a combined package of both automatic heating oil delivery and heating system repair. With an automatic oil delivery contract, the company tracks your home’s number two heating oil consumption and makes deliveries when your tank is running low. The household does not need to monitor the level of the oil tank or place individual orders.
Discount Oil Companies: also referred to as “COD Fuel” or “Cash Heating Oil” companies, discount oil companies are for households who are on a budget. With discount oil companies, in return for better prices, you monitor the oil level in your tank, and you place an oil order when the oil gauge dips below a quarter tank.
