Delaware County Homeowner’s Guide to Selecting an Oil Company

For Delaware households heating with number two heating oil, picking which of the 45 heating oil companies that serve Delaware makes a big difference.

Full Service Oil Companies: Homeowners who can afford a “set-it-and-forget-it” heating system choose 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 customers annual contracts which consist of a combined package of both automatic heating oil delivery and HVAC repair. With an automatic fuel oil delivery contract, the company tracks your home’s fuel oil consumption and makes deliveries when your tank is running low. The homeowner 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 households who are on a budget. With discount oil companies, in exchange for lower prices, you monitor the heating oil level in your tank, and you place an oil order when the oil gauge dips below a quarter tank. Examples of 2 Delaware cash heating oil companies serving Delaware include Mauger & Company Inc and Brandywine Fuel.
