…mindful of our humble beginnings, true to our values and the importance of treating customers like friends (because they are).

NSC can trace its early roots to the contracting company, Nabbefeld Heating Company which opened in the late 1930’s.  The company was founded  by brothers John and Joe Nabbefeld. Due to rationing programs of the U.S. War Production Board during WWII, the company was forced to close after basic supplies were made unavailable.

In 1946, the Nabbefeld brothers began a new venture selling to contractors instead of doing contractor work. National Sales Company (NSC) was founded as a wholesale distributor primarily focused on heating products such as steam traps, radiators, fittings, and pipe. John Nabbefeld used his expertise as a pipe fitter and relationships with fellow pipe fitters and plumber friends to quickly establish a thriving business. Due to the fact that he was of German descent and the existing political climate post-WW2,  John incorporated his U.S. patriotism into the naming the new company National Sales Company and choosing Red, White, & Blue as its company colors.
