HVAC Training Programs in Illinois – Degrees, Certifications & Salaries

Connect With HVAC Schools

The Prairie State has a continental climate marked by cold winters and hot humid summers, making it a thriving environment for climate control professionals.

In fact, Illinois (IL) not only has a high demand for workers in heating, ventilation, air conditioning, and refrigeration (HVAC/R), but it also boasts a wealth of professional organizations that support men and women in this line of work. By illustration, the Illinois Plumbing, Heating, Cooling Contractors Association has been around for more than 120 years, striving to “protect the environment, health, welfare, and safety of the residents of Illinois.” The group provides legal representation with government regulatory agencies, networking events, educational training, scholarships, federated insurance, business discounts, and many other resources. The PHCC also has a Southwestern IL chapter, which exists among other professional HVAC contractors associations in the state.

HVAC workers in the Land of Lincoln and beyond take on varied responsibilities such as reading blueprints and diagrams; calculating heat loads and losses; installing, repairing, troubleshooting and maintaining HVAC components (e.g., refrigeration circuits, controls, hermetic compressors, heat pumps, split systems, package units, electric motors, relays, starters, water pumps, intake and exhaust fans, economizers, humidifiers, etc); keeping detailed client service records, vendor packing slips, and other paperwork; and offering customers recommendations on increasing energy efficiency of their HVAC systems.

Some of these skilled professionals focus on one type of equipment, manufacturer, or method, while others choose to become generalist technicians with more broad-based training and abilities. Regardless of one’s chosen path, all workers nationwide who handle refrigerants must achieve the EPA Section 608 certification, which is discussed in the last section of this guide.

This piece examines the thriving employment climate for HVAC workers in Illinois and nationwide, as well as the accredited training programs, salary potential, and credentialing requirements within the state.

Demand for HVAC Workers in Illinois

As mentioned in the introduction, the HVAC industry is currently booming. The Bureau of Labor Statistics (BLS 2019) projected a 13 percent increase in openings for HVAC professionals across the country between 2018 and 2028, more than double the average growth expected across all occupations during that time period, which is just 5 percent. This equates to 46,300 fresh opportunities in HVAC nationwide.

There is evidence that the prospects in Illinois are nearly as bright. In fact, Projections Central (2020) reported that there would be a 13.1 percent increase in HVAC positions in Illinois between 2016 and 2026, resulting in 920 new jobs in the state.

There are various reasons for this explosion in opportunities for trained HVAC workers. Not only do maintenance and service contracts guarantee a steady stream of work, but HVAC systems also need to be replaced every 10 to 15 years. In States like Illinois with marked temperature extremes during the winter and summer and in areas with high growth and rates of construction such as Chicago, the demand for HVAC services is strong. Additionally, old systems sometimes need to be retrofitted, particularly as legislation on environmental protection evolves. Furthermore, many businesses depend on climate-control systems and rely on the availability of skilled professionals to maintain all equipment and ensure it is in working order.

As of 2019, around one in ten HVAC workers were self-employed, and 64 percent worked in the contracting industry (BLS 2020). It is important to note that people in this profession experience a higher-than-average risk of injury compared to other occupations. This is due to the physical nature of the work, which can involve lifting heavy objects, changing out electrical wiring, and dealing with flammable substances. With the proper training and use of safety equipment, however, these problems can generally be kept to a minimum.

Some HVAC professionals in IL work normal business hours, but especially during the busy seasons, they may be called upon to work weekends, evenings, or holidays to meet the needs of clients.

There is abundant evidence that business is booming for Illinois HVAC workers. Indeed (2020) had a healthy 278 job posts calling for HVAC workers in cities across IL, including openings at Cahill Heating and Air Conditioning, Dependable Building Services, Inc., Williams Stoker and Heating Co., and Bratcher Heating and AIr, to name a few. Additionally, Monster (2020) had 348 posts with opportunities at Brines Refrigeration, Centurylink, Johnson Controls, Henkel, and Cybercoders, amongst others.

Illinois (IL) HVAC Technician Salary Data

Not only is the employment climate fertile for HVAC workers in Illinois, but it is also a relatively lucrative profession, especially for a job requiring only one to two years of postsecondary training. In fact, the Bureau of Labor Statistics (2019) found that the 342,040 HVAC mechanics and installers nationwide boasted an annual average salary of $51,420. The following chart examines how the salaries of the 8,840 HVAC technicians in Illinois compared to national averages (BLS May 2019)

United States Illinois
Number of HVAC professionals employed 342,040 8,840
Average annual salary $51,420 $60,350
10th percentile $30,610 $28,480
25th percentile $37,660 $38,910
50th percentile (median) $48,730 $57,250
75th percentile $62,070 $80,400
90th percentile $77,920 $99,540


With the exception of those earning in the 10th percentile, the HVAC workers in IL fared much better than people in this industry nationwide. What makes this salary point particularly interesting is the fact that Illinois is one of the cheaper states to live in across the country. The Missouri Economic Research and Information Center (MERIC 2020) found that the Prairie State was the twentieth most affordable, with below-average costs for everything except for transportation

HVAC Licensing and Certification in Illinois (IL)

In addition to seeking out the proper training, aspiring HVAC mechanics, technicians, and installers in IL also must receive the proper credentialing prior to beginning work. As previously mentioned, there is one mandatory national certification for all people who work with refrigerants: the EPA Section 608 certification. Training for this is typically provided in HVAC/R certificate and degree programs. There are four kinds:

  • Type 1 (small appliance)
  • Type 2 (high-pressure appliances)
  • Type 3 (low-pressure appliances)
  • Type 4 (universal)

Additionally, there are several organizations that offer employment-ready credentialing in this field. For example, HVAC Excellence 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).

To learn about the gamut of national certifications available, check out the HVAC certifications page.

Finally, while there is currently no state license required for HVAC workers in Illinois, local permitting and registration requirements vary:

  • For example, the City of Evanston requires all mechanical contractors (including HVAC workers) to seek a license from the city. To qualify, candidates must pass an open book exam on the International Mechanical and Fuel Gas Codes and pay $100. The Evanston license can be renewed annually.
  • The City of Elgin—notably a top-paying metropolitan region for HVAC professionals in IL—requires its warm air heating contractors to register with the city’s Department of Community Development. The qualifying exam takes three to four hours to complete, covering three main areas: duct design, venting and combustion air, and installation parameters. The exam costs $100, and for successful applicants, the registration fee is $25 annually.

In sum, all interested HVAC workers in IL and other states are strongly encouraged to check with local credentialing authorities prior to beginning any work in maintenance, installation, or repair of these systems.
