Join the DOC Family of Customers
Become a CustomerBecoming a DOC customer is straight forward, and we’ll help you choose the setup that fits your needs.
Whether you’re a homeowner looking for dependable fuel delivery and service, or a business that needs commercial fuel support, the goal is the same: clear next steps, a simple process, and a local team you can reach when it matters. DOC offers accounts for both residential and commercial customers.
If you would like to be considered for charging terms, you can complete the appropriate application form below. If you need service sooner or prefer not to have a credit check, we can help you get set up on a COD basis where applicable.
Our application process includes a hard credit inquiry.
If you do not want a credit check, do not complete the application form. Instead, call your local DOC Home Comfort Center and a customer service representative can set up a COD account where applicable by product.
Applications for charging terms are processed within 24 to 48 hours of receipt during normal business hours. If you need an immediate delivery within the next 48 hours, call your local DOC Home Comfort Center or 1-800-794-4362 to arrange payment so we can get you the fuel you need right away. Then you can proceed to fill out the application for future deliveries.
If you have questions about the application process, call 207-834-5027 and ask for the credit manager.
Not sure which option is right?
If you are unsure whether you should apply for residential terms, commercial terms, or set up COD first, call and we will walk you through it. The goal is to get you set up the right way so deliveries, payments, and service requests stay simple.
