Darien Homeowner’s Guide to Selecting an Oil Company
For Darien families heating with number two heating oil, picking which of the 36 heating oil companies that serve Darien can drastically impact the cost of home heating.
Full Service Oil Companies: Homeowners who can afford 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 oil delivery and furnace 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 customer 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 customers who are on a budget. With discount oil companies, in exchange for lower prices, you monitor the heating 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.
