How many heating and air conditioning contractors are in Maine?

The Census Bureau counted 751 businesses with employees in Maine in 2022, in the category “Plumbing, heating and air-conditioning contractors”. That ranks Maine 38th of 50 states, one of the smaller markets, and 1% of the US total. 87% of them have fewer than 10 staff, and 46 have 20 or more.

Together they employ 4,613 people, with an average yearly payroll of $378,485 per business. The three busiest counties hold 52% of them, so competition is packed into a few places.

With 1,395,722 residents (Census, July 2023), that is one business for every 1,858 people, against 3,051 nationally: fewer residents per business than the US average, so more competition for each job.
