Why Miller Oil

Four Generations of Service
In 1939, Alexander S. Miller founded Miller Oil Company to serve the heating and cooling needs of the greater Enfield community. His son, James R. Miller Sr and grandson James R. Miller Jr. followed him into the family business. Today grandson Charles H. Miller, along with great grandson Douglas J. Miller, continue to operate the company with the same dedication to providing quality service.
