For Darien residences heating with number two heating oil, picking which of the 35 heating oil companies that serve Darien 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 21 “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 fuel oil delivery and boiler repair. With an automatic number two heating oil delivery contract, the company tracks your home’s number two heating oil consumption and makes deliveries when your tank is running low.
