Our history goes back a hundred years and extends across a variety of fields. What is consistent is our company’s devotion to providing excellent home and commercial products and an unimpeachable brand of customer service.
John Duffy Energy Services was founded in Newark, NJ in 1891. Back then, it was a furniture-moving company. The business eventually expanded into energy and fuel, which began with coal and, today, involves everything from heating oil to natural gas, from fleet fueling to diesel--even power washing!
Through it all, John Duffy Energy Services has been held in high esteem by clients from all over New Jersey, who regard us as authoritative in our field and devoted to providing affordable, high-quality energy and fueling solutions, both for your commercial and residential needs.
