Questions

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

The Census Bureau's County Business Patterns counted 781 plumbing, heating and air-conditioning contractors with paid employees in Maine in 2023. That ranks Maine number 37 among the 50 states and the District of Columbia.

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

Between 2017 and 2023 the count grew (18.5%), from 659 to 781. 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.

These counts describe how many businesses already exist. They say nothing about demand, profit, competition near you or how much any owner earns, and we make no estimate of income. Check local licensing, costs and rules before acting on any figure here. See the disclaimer.
