Cos Cob Homeowner’s Guide to Selecting an Oil Company
For Cos Cob families heating with oil, picking which of the 28 heating oil companies that serve Cos Cob plays a big role in determining how much money is spent on heating each winter.
Full Service Oil Companies: Homeowners who can afford a “set-it-and-forget-it” heating system pick one of the 17 “full-service” oil companies that serve Cos Cob. Full service companies such as Montanari Fuel Service Inc or Rural Energy LLC offer customers annual contracts which consist of a combined package of both automatic fuel oil delivery and boiler repair. With an automatic oil delivery contract, the company tracks your home’s oil consumption and makes deliveries when your tank is running low. The client 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 families who are looking to save money. 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. Some of the 2 Cos Cob cash heating oil companies serving Cos Cob include Affordable Heating & Fuel LLC and Elshaddai Oil Company.
