Hawaii had 403 plumbing, heating and air-conditioning contractors in 2023, ranking number 44 among the 50 states and the District of Columbia. Together they employed 3,944 people and paid $335 million in annual payroll, an average of 9.8 employees per site.

These businesses make up 1.22% of every employer establishment in Hawaii, close to the 1.33% national share. A site count is not the same as the number of companies: a chain with 40 locations counts 40 times.

54% of plumbing, heating and air-conditioning contractors in Hawaii have fewer than 5 employees, against 58% across the U.S.

Hawaii holds 0.4% of the nation's plumbing, heating and air-conditioning contractors and 0.4% of all U.S. employer establishments, so, measured against the state's overall size, the trade is about as common as in the country as a whole. The most common size class is under 5 employees (218 sites). Average payroll per employee is $84,947, against $73,693 for the U.S. trade.

Questions

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

The Census Bureau's County Business Patterns counted 403 plumbing, heating and air-conditioning contractors with paid employees in Hawaii in 2023. That ranks Hawaii number 44 among the 50 states and the District of Columbia.

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

Between 2017 and 2023 the count grew (8.0%), from 373 to 403. 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.
