Illinois, city by city.
Illinois has 4,070 plumbing, heating and air-conditioning contractors with paid employees (Census County Business Patterns 2023): 3.2 for every 10,000 residents, against 3.3 nationally.
The Census counts plumbing, heating and air-conditioning contractors together, so this figure includes HVAC companies.
