Cos Cob Homeowner’s Guide to Selecting an Oil Company
For Cos Cob households heating with heating oil, picking which of the 29 heating oil companies that serve Cos Cob can drastically impact the cost of home heating.
Full Service Oil Companies: Homeowners who value a “set-it-and-forget-it” heating system pick one of the 18 “full-service” oil companies that serve Cos Cob. 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 fuel oil delivery and boiler 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 client does not need to monitor the level of the oil tank or place individual orders.
Discount Oil Companies: Also known by the names “COD Fuel” or “Cash Heating Oil” companies, discount oil companies are for clients who are budget-conscious. With discount oil companies, in exchange for lower prices, you monitor the fuel 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 Cos Cob cash heating oil companies serving Cos Cob include Affordable Heating & Fuel LLC and Elshaddai Oil Company.
