Darien Homeowner’s Guide to Selecting an Oil Company
For Darien homes heating with heating oil, selecting 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 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 households annual contracts which consist of a combined package of both automatic number two heating oil delivery and HVAC repair. With an automatic heating oil delivery contract, the company tracks your home’s fuel 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 clients who are on a budget. 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. A few of the 2 Darien cash heating oil companies serving Darien include Affordable Heating & Fuel LLC and HiHo ClicknGo.
