Darien Homeowner’s Guide to Selecting an Oil Company
For Darien households heating with heating oil, picking which of the 36 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 pick one of the 22 “full-service” oil companies that serve Darien. Full service companies such as Montanari Fuel Service Inc or Rural Energy LLC offer customers annual contracts which consist of a combined package of both automatic oil delivery and boiler repair. With an automatic fuel 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: Often called “COD Fuel” or “Cash Heating Oil” companies, discount oil companies are for customers who are looking to save money. With discount oil companies, in return for better prices, you monitor the oil level in your tank, and you place an oil order either when the level runs low or just before a major snowstorm. Some of the 2 Darien cash heating oil companies serving Darien include Affordable Heating & Fuel LLC and HiHo ClicknGo.
