How many heating and air conditioning contractors are in New Hampshire?

The Census Bureau counted 759 businesses with employees in New Hampshire in 2022, in the category “Plumbing, heating and air-conditioning contractors”. That ranks New Hampshire 37th of 50 states, one of the smaller markets, and 1% of the US total. 84% of them have fewer than 10 staff, and 56 have 20 or more.

Together they employ 5,474 people, with an average yearly payroll of $549,590 per business. The three busiest counties hold 68% of them, so competition is packed into a few places.

With 1,402,054 residents (Census, July 2023), that is one business for every 1,847 people, against 3,051 nationally: fewer residents per business than the US average, so more competition for each job.
