How many heating and air conditioning contractors are in New Jersey?
The Census Bureau counted 3,500 businesses with employees in New Jersey in 2022, in the category “Plumbing, heating and air-conditioning contractors”. That ranks New Jersey 8th of 50 states, one of the largest markets in the country, and 3% of the US total. 81% of them have fewer than 10 staff, and 284 have 20 or more.
Together they employ 29,679 people, with an average yearly payroll of $636,223 per business. The three busiest counties hold 32% of them, so the work is spread across the state.
With 9,290,841 residents (Census, July 2023), that is one business for every 2,655 people, against 3,051 nationally: fewer residents per business than the US average, so more competition for each job.
