HVAC Training Schools and Certifications in Wisconsin

In the Badger State, the frigid winters and humid summers provide a host of job opportunities for those interested in heating, air conditioning, and ventilation (HVAC). In fact, U.S. Climate Data found that the winter months bring average low temperatures beneath 20 degrees Fahrenheit, while in July the temperature can exceed 80. Living in these varied conditions requires some form of indoor climate-control system, which are installed and maintained by skilled HVAC workers.

To illustrate the strength and importance of the HVAC industry, a number of national organizations and unions operate throughout Wisconsin. For example, the Plumbing-Heating-Cooling Contractors Wisconsin Association (PHCC) and Master Plumbers/Heating Cooling Association of Wisconsin (MP/HC) is one such institution, which has been in existence for over 120 years and offers a wide array of benefits to members, such as discounts on various educational programs, a quarterly newsletter, legislative and regulatory representation, networking opportunities, and much more.

HVAC workers in Wisconsin may also choose to seek membership with the Plumbers and Steamfitters Local 434, a local union that represents over 1,200 pipe trades workers in Central and Western Wisconsin. These skilled professionals lay the groundwork for many HVAC systems. Benefits available to members include access to a healthcare fund, a retirement plan, a pension fund, networking opportunities, and training in the form of an apprenticeship program, explored at length below.

Aspiring HVAC workers in Wisconsin should have a thorough understanding of the day-to-day responsibilities of these professionals. In general, these workers:

Verify compliance with necessary laws
Perform calculations regarding heat load and loss
Test equipment to ensure it is working properly
Calibrate controls of the HVAC systems
Maintain service records
Educate customers on system use and energy conservation
Travel to different worksites
Maintain credentials and licensure
Examine and interpret blueprints

Furthermore, anyone working with refrigerants in Wisconsin must maintain active EPA Section 608 Certification, as it is required under law.

This guide offers salary statistics, job prospects, information about various Wisconsin HVAC schools that offer training, and a detailed breakdown of the credentialing required to work in the state.

Occupational Demand for HVAC Professionals in Wisconsin

The Bureau of Labor Statistics (BLS May 2023) reported that there were 397,450 HVAC professionals currently working across the nation, earning an annual average wage of $59,620. The future for HVAC mechanics and installers looks bright, as well; by illustration, the BLS (2023) anticipated that the industry would grow 6 percent between 2022 and 2032, an increase of 23,000 jobs nationwide. To put this into perspective, all U.S. industries combined are slated to expand by an average of only three percent. Additionally, Projections Central (2024) predicted that HVAC jobs in Wisconsin would grow by 7.7 percent between 2020 and 2030, an addition of 580 new positions.

Of course, several factors are driving this growth. For one, existing HVAC systems must generally be replaced every 10 to 15 years, a process that requires the skill and expertise of a trained technician. Also, nearly all new buildings in Wisconsin are constructed with some form of climate-control system. Finally, HVAC laws and regulations are constantly changing; as a result, equipment routinely needs to be updated to stay in compliance with local ordinances.

For some, viewing available jobs is the easiest way to conceptualize the demand for HVAC workers. For example, a job search on Monster (April 2024) for “HVAC jobs in Wisconsin” yielded over 1,000 results with companies like AMA Heating and Air Conditioning, Brunswick Corporation, Green Bay Packers, Tradesmen International, Inc., Ultimate Air, ThedaCare, Inc., and 3M. A related search on Indeed (April 2024) returned 525 results with organizations such as Nextech, Melink Corporation, Advocate Aurora Health, State of Wisconsin, Capital Construction Services, LLC, and Insight Global. In sum, the industry is booming in Wisconsin.

How Much Do HVAC Techs Make in Wisconsin?

According to the Bureau of Labor Statistics (May 2023), HVAC professionals earn relatively competitive salaries, particularly for positions that may require just two years of post-secondary training. BLS (May 2023) states that the annual mean wage for HVAC workers nationwide was $59,620 per year, while the annual mean wage for HVAC technicians in WI was even higher at $60,970 per year. In more detail, here were the salary percentiles of HVAC professionals across the US and in Wisconsin specifically:

	United States	Wisconsin
Number of HVAC professionals employed	397,450	6,190

50th Percentile (Median)	$57,300	$59,520
75th Percentile	$71,120	$70,140
90th Percentile	$84,250	$83,340

The national figures were slightly different according to another source of data, PayScale (April 2024), which relies on self-reported salaries. Among the HVAC workers reporting their annual salaries, Payscale found these percentiles:

10th percentile: $36,000
50th percentile (median): $55,000
90th percentile: $83,000

As noted above, the average salary for HVAC workers in Wisconsin is higher than the nation’s average salary. As with any salary projections, taking into account the cost of living is also important. As such, the Missouri Economic Research and Information Center (MERIC 2024) found that WI had the 24th lowest cost of living in the United States. Aspiring HVAC workers in Wisconsin are encouraged to keep this in mind.

HVAC Apprenticeships in Wisconsin
