Anyone working as an HVAC contractor in America’s Dairyland is required to register with the Department of Safety and Professional Services. Registration consists of filling out a simple, two-page form. This may be done by the owner, a partner, or the chairman of the board or CEO if it’s a corporation.

The registration costs $160, plus a $15 filing fee. It’s valid for four years.

If you are only to be working on your own property – including a property owned by the business entity – you do not have to register.


Certification in Wisconsin is optional but can help your job prospects. With certification, you are categorized as an “HVAC Qualifier.” This also makes your employer a certified HVAC business. One advantage is that by law, local jurisdictions cannot put further requirements on you.

There is an exam associated with this. The prerequisites for taking the exam are any one of the following:

Experience: at least 1000 hours per year for at least 4 years “in supervising or performing the design, installation, servicing or maintenance of HVAC systems or equipment”.

Education: a minimum of four years in a school of mechanical engineering or in an accredited college; technical, vocational or apprenticeship school; or university, in an HVAC-related program.

A combination of the experience and education totaling four years. Exam dates are listed on the application form itself. Fees are $15 for an application fee and $25 for the open-book exam.

Local Regulations

Under state law, cities, counties, town and villages are restricted in what further restrictions they can make requiring certification.

The types are based on the size or type of appliance you’re working with.

The Wisconsin Division of Professional Credentialing is responsible for conducting the HVAC Qualifier Examination. The test itself evaluates your knowledge regarding safety measures, regulations, and various HVAC procedures. The exam is open-book, so you can always consult from course books.

To pass the examination, it is necessary that you score at least 70%. The result is emailed to you after 21 days, while the validity remains for four years.

The best way to clear each examination is either by enrolling in an HVAC Training program or an apprenticeship. Both options provide you with basic and practical knowledge of carrying out HVAC procedures.

    • Thanks for your comment, Bill. The requirements vary widely from state to state – Wisconsin is one of a handful of states that don’t have statewide requirements specifically for HVAC techs. Any regulation is local, and I didn’t want to get into investigating every county and city.
      Many states do have different licenses for some of the areas you mention.
