Step By Step Guide To Become A HVAC Technician In Illinois 2025
Step 1: Obtain a High School Diploma or GED
Completing high school or obtaining a GED is the foundational requirement. Focus on courses in mathematics, physics, and vocational studies if available. These subjects provide essential knowledge for HVAC systems.
Step 2: Enroll in an HVAC Training Program
Illinois requires individuals to complete an approved HVAC training program which can be found at community colleges, trade schools, or technical schools. These programs typically last between six months to two years. They cover core topics such as:
- Thermodynamics
- Refrigeration
- Electrical systems
- HVAC design principles
Hands-on training in laboratory settings is often included. Examples of regional institutions offering these programs are City Colleges of Chicago and College of Lake County.
Step 3: Gain Apprenticeship Experience
Upon completing your education, pursue an apprenticeship to gain practical experience. Illinois supports apprenticeships through programs registered with the Illinois Department of Employment Security (IDES). These programs generally last 3 to 5 years and offer wage increases as your skills develop.
Step 4: Obtain a State HVAC Certification
Illinois does not mandate state certification for HVAC technicians. However, individual cities or counties might require local licensing. For example, Chicago requires specific licensing through its Department of Buildings. Verify local requirements where you intend to work.
In addition, you should pursue Environmental Protection Agency (EPA) Section 608 Certification to handle refrigerants legally. You must pass an examination covering specific types or classes of refrigerants.
Step 5: Consider Higher Certifications
Earning advanced certifications from recognized entities such as North American Technician Excellence (NATE) can improve employability and career progression. NATE offers certifications including HVAC efficiency and sustainable design, which can be essential as green building initiatives grow.
Step 6: Find Employment
Seek employment with established HVAC companies in Illinois. Utilize platforms like the Illinois Department of Employment Security’s IllinoisJobLink.com or resources like trade school career centers. Entry-level positions often involve assisting experienced technicians in maintaining, installing, and repairing systems.
Step 7: Continue Education and Stay Informed
Continual learning is crucial as HVAC technology evolves. Enroll in workshops, online courses, or attend industry seminars. Stay informed about Illinois-specific HVAC industry updates by visiting the Illinois Department of Labor or joining professional associations like the Illinois Plumbing, Heating, Cooling Contractors Association (ILPHCC).
Step 8: Explore Self-Employment or Further Specialization
After obtaining enough experience, consider starting your own business. You may need a contractor’s license if venturing into self-employment. Refer to the Illinois Secretary of State for business registration details.
For more specialization, investigate niche areas such as residential, commercial, or industrial HVAC systems. Each sector requires different expertise and may involve additional training or certifications.
