Carr & Duff Our Beginning


Mr. Edward Duff began working as a lineman at the Philadelphia Electric Company in 1949. In 1958, Ed and fellow PECO lineman foreman Harold (Hap) Carr founded Carr & Duff with a vision to fulfill the electrical construction needs of Philadelphia’s burgeoning suburbs.

From humble beginnings – with one line truck, Carr & Duff earned utility, city and state contract work. Carr & Duff became a National Electrical Contractors Association member and International Brotherhood of Electrical Workers member in 1978. The company has become a premier electrical contractor in the Greater Philadelphia and Tri-State Area.

Carr & Duff is a family owned business with 60 years of electrical construction excellence serving not just the Philadelphia Metropolitan Area but has served utilities and customers throughout states up and down the East Coast.
