Delaware County Homeowner’s Guide to Selecting an Oil Company
For Delaware homes heating with number two heating oil, choosing which of the 43 heating oil companies that serve Delaware makes a big difference.
Full Service Oil Companies: Homeowners who value a “set-it-and-forget-it” heating system pick one of the 319 “full-service” oil companies that serve Delaware. Full service companies such as Royal Petroleum Inc or Wister Coal & Fuel Oil Co offer families annual contracts which consist of a combined package of both automatic heating oil delivery and boiler repair. With an automatic number two heating oil delivery contract, the company tracks your home’s fuel oil consumption and makes deliveries when your tank is running low. The household 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 either when the level runs low or just before a major snowstorm. Some of the 2 Delaware cash heating oil companies serving Delaware include Mauger & Company Inc and Brandywine Fuel.
