Questions
How many plumbing, heating and air-conditioning contractors are in Louisiana?
The Census Bureau's County Business Patterns counted 1,623 plumbing, heating and air-conditioning contractors with paid employees in Louisiana in 2023. That ranks Louisiana number 25 among the 50 states and the District of Columbia.
Is the number of plumbing, heating and air-conditioning contractors in Louisiana growing?
Between 2017 and 2023 the count grew (12.0%), from 1,449 to 1,623. 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.
