The state of Minnesota does not impose state-level licensing requirements for either HVAC-R technicians or contractors, however, many cities, including Minneapolis and St. Paul, do require municipal certification.

Even outside the cities or towns with HVAC license requirements, competition can be fierce for entry-level HVAC technician jobs. With the industry becoming increasingly high-tech, there is little room to advance for beginners who come in without some knowledge and training in modern HVAC system installation and maintenance.

Proper training through an HVAC trade school or technical college program helps ensure that competitive advantage, while also satisfying local licensing requirements and federal-level EPA Section 608 certification for handling controlled refrigerants.

The twin cities of Minneapolis and St. Paul both have restrictions and qualifications for technicians who are allowed to perform HVAC installation or service within the city limits. Conveniently, as the cities are located right next to one another, they have a reciprocity agreement so you can earn your certificate of competency (known as comp cards in the trade) in either city and then apply immediately for a card in the other. Additionally, St. Paul will recognize cards from any other Minnesota municipality with equivalent competency requirements.

Obtaining a Minneapolis and/or St. Paul Certificate of Competency

Certificates of competency for the mechanical trades are issued by:

  • Safety and Inspections Department
  • Minneapolis – Construction Code Service

Certificates are issued for the following trades common among HVAC professionals:

  • Refrigeration – Refrigeration system equipment install and repair.
  • Steam / Hot Water – Steamfitting and piping installation and repair.
  • Gasfitter – Gas system and fuel burner system installation and repair.
  • Oil Burner – Oil burner system installation and repair.
  • Ventilation – Installing systems that move natural air in or out of a space by mechanical means.
  • Warm air – Installing systems that use mechanical systems to move warm air into a space.

Depending on the work your employer performs, you may need comp cards in some or all of these fields. The master and journey levels for many of the occupations have different system size or capacity limitations; consult the Safety and Inspections Department for details.

It’s important to note that the Ventilation and Warm air cards are required only for workers performing system installations. Servicing those systems does not require a comp card.

  • Journeyman Level

    The journeyman level of qualification has the following requirements:

    • Obtain 4 years of on-the-job experience as a state-registered apprentice AND 144 hours per year of classroom education (in Minneapolis, 576 hours of class time in the preceding 5 years is also accepted)


    • Obtain 7 years of on-the-job experience in the field (only in St. Paul)


    • Pass the certification exam offered by the city with a 70 percent score or better

    The application fee is $55 in St. Paul.Minneapolis does not charge an application fee, but there is a $105 exam fee.

  • Master Level

    Obtaining a master’s certificate follows the same process, but costs $82.50 (in St. Paul only) and requires at least one year of experience as a certified journeyman, with no less than five years of total, cumulative experience in the field. Additionally, you have to pass the certification exam with a score of 75 percent or better.In St. Paul, examinations for warm air and ventilation are offered in January and July each year, while the other trade tests are offered in April and October. Minneapolis does not have a published test schedule; check the Construction Code Service website for announcements for application acceptance and exam scheduling.Certifications expire on December 31 of the year of issue in St. Paul, and November 1 in Minneapolis. They can be renewed for the same cost as the original application fee in St. Paul, and $30 per category in Minneapolis.Master certificate holders are allowed to become contractors by obtaining a contractor’s license.

    Although the state does not require contractor licensing, if you do become a mechanical contractor you are required to file a $25,000 Mechanical Contractor bond with the state Department of Labor and Industries.

Other Cities in Minnesota Requiring Licenses or Certifications in HVAC Work

Other Minnesota municipalities may have their own licensing or certification procedures; check with the city where you intend to practice for details.

Federal EPA Certification Requirements

HVAC work is not only regulated by state and local governments, but also by the Federal government. Section 608 of the Clean Air Act covers the use and handling of certain controlled gases, such as Freon and ammonia, which are commonly used in AC and refrigeration systems. The act mandates that anyone performing work or otherwise testing these systems receive a certification in order to do so in compliance with recovery and recycling standards.

There are four different types of Section 608 certification:

Small appliances service and repair (self-contained appliances with 5 pounds of refrigerant or less)

Almost all trade school or community college programs in HVAC-R include comprehensive coverage of the Section 608 requirements. Many of them include the test itself as a part of their core curriculum, allowing you to receive certification before you even actually graduate and enter the job market.

HVAC-R Job Prospects and Industry Growth in Minnesota

Minnesota’s construction industry projections are rated as steady by Finance and Commerce magazine, an outlook validated by the state’s own Employment and Economic Development council, which foresees only a moderate seven percent growth rate in the HVAC field over the next decade.

But those numbers only tell part of the story. The Finance and Commerce article also points out that many construction-related fields have a shortage of skilled labor available, a state of affairs that drives demand and increases wages for qualified technicians. An HVAC-R technician with a trade school certificate or an associate’s degree from a community college HVAC program can expect to have both better entry-level job prospects and a longer and more lucrative career in the industry.
