Darien Homeowner’s Guide to Selecting an Oil Company
For Darien homes heating with oil, choosing which of the 35 heating oil companies that serve Darien makes a big difference.
Full Service Oil Companies: Homeowners who prefer a “set-it-and-forget-it” heating system select 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 fuel oil delivery and heating system repair. With an automatic oil delivery contract, the company tracks your home’s fuel oil consumption and makes deliveries when your tank is running low. The homeowner 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 households who are looking to save money. With discount oil companies, in exchange for lower prices, you monitor the oil level in your tank, and you place an oil order when the oil gauge dips below a quarter tank. Some of the 2 Darien cash heating oil companies serving Darien include Affordable Heating & Fuel LLC and HiHo ClicknGo.
