Darien Homeowner’s Guide to Selecting an Oil Company
For Darien residences heating with oil, choosing which of the 36 heating oil companies that serve Darien is an important decision.
Full Service Oil Companies: Homeowners who value a “set-it-and-forget-it” heating system choose 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 clients annual contracts which consist of a combined package of both automatic fuel oil delivery and heating system repair. With an automatic fuel oil delivery contract, the company tracks your home’s fuel 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 families who are looking to save money. With discount oil companies, in exchange for lower prices, you monitor the heating 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.
