Questions

How many plumbing, heating and air-conditioning contractors are in New Jersey?

The Census Bureau's County Business Patterns counted 3,454 plumbing, heating and air-conditioning contractors with paid employees in New Jersey in 2023. That ranks New Jersey number 8 among the 50 states and the District of Columbia.

Is the number of plumbing, heating and air-conditioning contractors in New Jersey growing?

Between 2017 and 2023 the count shrank (4.6%), from 3,621 to 3,454. Across the United States the count changed by +8.5% over the same period. These years include the 2020 pandemic.

Does this count include self-employed owners with no staff?

No. County Business Patterns covers establishments with at least one paid employee. A sole proprietor with no employees is counted in a separate Census series called Nonemployer Statistics, which this site does not use yet, so the real number of people working in this trade is higher than the figure shown.
