Darien Homeowner’s Guide to Selecting an Oil Company
For Darien families heating with heating oil, choosing which of the 36 heating oil companies that serve Darien is an important decision.
Full Service Oil Companies: Homeowners who can afford 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 families annual contracts which consist of a combined package of both automatic fuel oil delivery and HVAC repair. With an automatic heating oil delivery contract, the company tracks your home’s oil consumption and makes deliveries when your tank is running low. The family 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 budget-conscious. 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. A few of the 2 Darien cash heating oil companies serving Darien include Affordable Heating & Fuel LLC and HiHo ClicknGo.
