Illinois HVAC license requirements

As mentioned, Illinois doesn’t have any statewide licensure or certification requirements to become an HVAC technician as states like Florida do.

However, depending on where you live in Illinois, there’s a good chance that your city, county, or municipality has requirements in place. Therefore, it’s important that you check your local guidelines to find out what those requirements are. 

In Chicago, for example, there are contractor license requirements in place that vary according to the value of the projects you plan to work on. These classifications range from Class A to Class E with Class A having no restrictions and a Class E license having the most restrictions. 

For example, if you have a Class E license in Chicago, you can only work on projects with a value of up to $500,000, while a Class A license can work on any project no matter the cost. 

While Chicago doesn’t require an official HVAC license, other cities like Springfield do. To receive your HVAC license in Springfield and many other cities and counties in IL, you’ll have to pass a certification exam. 

Additionally, if you plan to start your own HVAC company, you’ll have to obtain a business license regardless of where you live.

Illinois HVAC certification requirements

While the state of Illinois doesn’t have any statewide license or certification requirements, there are several HVAC certifications you’ll have to obtain if you hope to get hired as a technician. 

EPA 608 certification

The EPA 608 certification is required for all HVAC technicians who plan to work on any type of equipment containing refrigerant. The goal, is to get you to understand how detrimental refrigerant is to the atmosphere and how to best contain it when you’re servicing, repairing, installing, or removing HVAC equipment. 

There are four different types of 608 certifications including Type 1, Type 2, Type 3, and Type 4. Make sure to check which Type the HVAC equipment you plan to work on falls into. If you want to be on the safe side, however, you should get your Type 4 certification. Type 4 is also known as a Universal certification because it allows you to work on any type of HVAC equipment. 

Because the EPA 608 Certification exam is one of the most important you’ll take as an HVAC technician, it’s important that you prepare for it accordingly. The best way to do that is with our EPA 608 Certification Course & Exam Program where you can study prep materials for the exam and take it online!

Workers’ compensation
