We have already told you about the many financial and non-financial benefits of becoming an HVAC tech in Illinois.  One benefit which has both financial and non-financial aspects  is it is relatively easy to become an HVAC tech.  While Illinois does not require a license, there are some requirements.  Here we explain.


The first three very basic requirements are:


  1. You must be at least 18 years old.
  2. You must have a high school diploma or GED equivalent.
  3. You must have a valid driver’s license.


There are two options for becoming trained.  You must be trained to take the EPA Section 608 Certification Exam.


  1. Attend a community or technical college (usually two years) or trade school (usually six to nine months).
  2. Receive on-the-job training (for which you may get paid) by becoming an apprentice with an HVAC contractor. This apprenticeship generally lasts two years.

EPA Certification


Any HVAC technician handling controlled refrigerants found in refrigeration and AC systems must pass the EPA Section 608 Certification Exam.  There are four different levels of certification.


  1. Type I for servicing small appliances containing five pounds of refrigerant or less.
  2. Type II for servicing high pressure units that contain five pounds or more of refrigerant.
  3. Type III for servicing or disposing of low-pressure appliances.
  4. Universal – which covers all three of the above.

NATE Certification

While not required, it is a good idea to receive certification from North American Technical Excellence (NATE) – a large, non-profit certification organization for HVAC technicians.  This certification is broader than EPA certification.  There are also four types of NATE certification:


  1. Ready-to-Work Certificate. Earn this after passing an online entry-level exam focusing on essential job skills.
  2. HVAC Support Technician. This certificate is for technicians working to advance their careers.
  3. Core and Specialty Test. This certificate is available for technicians with at least two years of experience.
  4. Senior Level Efficiency Analyst. This is the highest NATE certification, and applicants must hold at least two other NATE certifications before taking this exam.
