Welcome, Ultimate Oil Customers!

We recently had the privilege of acquiring the legacy and clientele of Ultimate Oil, following the retirement of its owners, Mr. and Mrs. Caldwell. We are pleased to have the opportunity to provide home comfort to clients of a fellow family-owned heating oil company in Greater Hartford. Here at Wyman, we look forward to providing the same high level of dependability and customer service that you received with Ultimate Oil. Welcome to the family!

You may know us best as your local heating oil company, but we’re proud to have expanded our offerings to propane customers in the Greater Hartford area. See if we deliver to your town!
