Illinois HVAC License: Everything You Need to Know

Starting an HVAC business in Illinois is easier than you think. Get your start in the industry by obtaining your Illinois HVAC license. In this guide, you’ll learn about licensing requirements and the benefits of the profession. 

Do You Need a License in Illinois to Become an HVAC Technician?

No, Illinois does not require a state license. However, to open an HVAC contracting business, you will need a business license.

What are the Different Types of HVAC Licenses?

The following organizations issue HVAC certifications: the Environmental Protection Agency (EPA), the North American Technical Excellence (NATE) and the American Society of Heating, Refrigeration and Air Conditioning Engineering (ASHRAE).

EPA Certifications

Anyone who works with refrigerants must obtain the EPA certification. The EPA offers four levels of certification:

  • Type I for servicing small appliances

  • Type II for servicing or disposing of high to very-high pressure appliances

  • Type II for servicing low-pressure appliance

  • Universal, covering all three types

All applicants must pass the EPA's core section, which covers knowledge on ozone, depletion, the Clean Air Act and the Montreal Protocol, and Section 608 regulations. This certification never expires. 

NATE License Certifications

NATE certifications are more comprehensive than EPA certifications. You'll find four different types of NATE license certifications:

  • Ready-to-Work Certificate: An entry-level exam available online focusing on essential job skills

  • HVAC Support Technician: A certificate for technicians working toward advancing within the profession

  • Core and Specialty Test: A certificate for technicians with at least two years of experience

  • Senior Level Efficiency Analyst: A certificate for technicians seeking the highest NATE designation. Applicants must hold at least two NATE certifications before taking the exam.

ASHRAE Certifications

HVAC designers and engineers create comfortable indoor environments. Certified HVAC Designer is one of the most popular. This designation demonstrates your ability to size equipment properly, perform load calculations, and create piping design.

Because Illinois does not have designations for apprentice, journeyman or master HVAC professionals, pay varies. Entry-level technicians earn about $32,460 per year. The most highly experienced technicians earn as much as $84,990.

Benefits of Getting an HVAC License

The HVAC industry keeps growing. Getting an Illinois HVAC license or certification validates your knowledge as a professional technician. You'll earn more money as employers will pay more for those who have greater knowledge and experience in the industry. If you start your own business, the necessary licenses will give your customers peace of mind and may result in more sales. 

How Much Does It Cost to Get an HVAC License in Illinois?

EPA 608 Basic Certification is $24.95 for the initial test and $5.95 for each additional attempt. Some HVAC schools include the cost of an initial test in the tuition. Check with your school or organization administering the exam to get specific costs.
