In Illinois, most Heating, AC & Refrigeration Mechanics enter through apprenticeship programs or trade school followed by on-the-job training. The typical path takes 3-5 years to reach journeyman status. Apprenticeships are offered through unions like UA Local 597 (Chicago), Pipefitters Local 493 (Rockford), and Sheet Metal Workers locals, as well as through contractor associations like IHACI (Illinois Heating and Air Conditioning Inc.).
