Illinois, being located far from the coasts, experiences typically continental climate, with cold winters, warm summers, and pleasant temperatures in spring and fall. The extreme temperatures sometimes experienced in this state mean that the HVAC industry here is thriving.

With the need for more-efficient HVAC systems to keep people safe and comfortable comes a demand for well qualified, trained professionals to install and repair their systems. Let’s take a look at what sort of education you’ll need to succeed in HVAC here.

Requirements to Be an HVAC Tech in Illinois

Illinois has no statewide license requirement for HVAC professionals, but licenses are available for a supervising electrician and for a plumbers’ apprentice and plumbing contractor. However, if you’ll be handling refrigerants, you’ll need to pass the EPA 608 certification, which is a federal requirement. You can learn more about the Illinois HVAC certification requirements here.

In order to practice as an HVAC technician in Illinois, you may need to check with the city where you intend to practice for licensing. The City of Evanston requires all mechanical contractors to be licensed from the city, while the City of Elgin requires HVAC contractors to register with the city’s Department of Community Development.

HVAC Excellence is an organization that has two main broad-based certifications: Heating, Electrical, Air Conditioning Technology (HEAT) and HEAT Plus. It also has various specialty certifications in areas such as green awareness, residential heat load analysis, and combustion analysis, to name a few.

North American Technician Excellence (NATE) has several core and specialty certifications in areas such as light commercial refrigeration, hydronics (gas or oil), and oil heating, as well as industry competency exams (ICE).

While neither NATE nor HVAC Excellence certification is required, they both help to show your qualifications to prospective employers or to well-versed clients.

HVAC Engineers will always need a university degree to practice, either an associate or 4-year Bachelor’s degree.

HVAC Tech Salary and Job Prospects in Illinois

In Illinois, the average annual salary of an HVAC worker is $51,590, which is equal to $24.80/hour avg. This is substantially higher than the national annual average salary of $47,380, or $22.78/hour. The earnings will vary with experience and from city to city, so while the Chicago metropolitan region employs the highest number of HVAC workers in the state, Elgin pays the highest average annual salary at $62,320, 20.8 % higher than the average salary for these workers in IL.

Job growth in the region is quite high, with a steady demand for HVAC workers in the state.

A higher degree in HVAC can definitely brighten your chances of getting into a good contracting firm or getting hired by a company looking for HVAC technicians.
