Keep Fill Service

To eliminate the worry of keeping track of your own fuel gauge and the possibility of running out of fuel at the worst possible time, we offer an automatic delivery service at no additional charge. There are many factors that are used to determine your oil consumption like the size of your house, efficiency of your equipment and your personal habits. It only takes a few deliveries for us to establish a reliable delivery schedule unique to your home or business. The longer you are an automatic delivery customer with us, the more accurate we become at estimating your heating oil needs.

Call-In Delivery

We are committed to providing each of our customers with the individualized service that best fits your needs. For some customers, it is a better decision to be in control of when your fuel oil is delivered. We recommend that you kindly contact our office when your tank gauge is between a quarter and eight full. This will give us sufficient time to schedule a delivery.

When to use fuel oil versus kerosene: If you have an indoor tank that is protected from the elements, use fuel oil. If you have an outdoor fuel tank that is exposed to cold wind, use kerosene, as kerosene does not gel when the temperature gets cold.
