Michigan HVAC Training & Certification

It’s no surprise that in Michigan—the Water Winter Wonderland—there are a wealth of opportunities and resources for heating, ventilation, and air conditioning (HVAC) professionals. ACHR News, a major HVAC media source based in Troy, Michigan (MI), covers industry news organized by region and the numerous forums and events that support these skilled people in their work.

Michigan HVAC technicians must have a mechanical contractor’s license from the Michigan Department of Licensing and Regulatory Affairs (LARA) to perform work beyond the replacement of minor parts or in working with portable units with less than 30,000 BTU/hr. Numerous professional trade organizations support HVAC workers in building their skills and promoting local advocacy. For instance, the Michigan Air Conditioning Contractors Association represents mechanical contractors and supports evolving local regulations in the profession.

So what is it that HVAC technicians, mechanics, and installers in Michigan do? HVAC workers monitor the performance of HVAC systems and their components (e.g., motors, electrical wiring, pipes, valves, humidifiers); repair broken equipment; counsel commercial and residential property owners on how to maximize efficiency; perform preventative maintenance on various parts (e.g., wiring fans, pumps, compressors, switches, gauges, controls); read blueprints and install systems; and maintain active credentialing by keeping up-to-date knowledge in the profession.

To become an HVAC mechanic, installer, or repairer in Michigan, you must receive proper professional training. This is important to ensure the proper functioning of machines, and HVAC work incurs a higher average rate of injury than other professions.

The Bureau of Labor Statistics (2025) points out relatively common problems for HVAC technicians include burns, electric shocks, and muscle strains. Handling refrigerants can be especially hazardous since contact with the skin can produce frostbite or even blindness. Therefore, it is imperative to learn about the best practices and procedures for handling equipment safely.

Most of Michigan’s HVAC employment opportunities call for knowledge of various systems such as geothermal, oil-burning, and electric. Additionally, certifications from national credentialing organizations such as NATE can also enhance a Michigan HVAC technician’s job candidacy.

Read on to learn about the promising job outlook for HVAC professionals in Michigan, including the salary prospects (statewide and regionally), accredited training, and how to pursue licensure.

HVAC Occupational Demand in Michigan

According to the Bureau of Labor Statistics (BLS 2025), HVAC technicians, mechanics, and installers can expect relatively high job growth in the years to come. The BLS projected a 9 percent increase in openings in this field between 2023 and 2033, which is faster than the average percent growth anticipated across all occupations (4 percent). Projections Central (2025)—a partner of the US Department of Labor—projected a 4.6 percent increase in HVAC opportunities across Michigan between 2022 and 2032.

To enhance one’s ability to secure a job in this field, many MI HVAC employers call for:

Driver’s license
Proof of HVAC technical education (certificate, diploma, or degree)
Experience on the job (three to five years preferred)
NATE certification(s)
Ability to pass a drug test

These professionals work in various environments since most structures in Michigan provide some form of climate control. HVAC technicians may work in homes, businesses, hospitals, schools, factories, and other environments. Since many HVAC contracting companies perform regular maintenance on equipment for customers in Michigan and systems generally need to be replaced every ten years, there is a steady stream of employment.

Furthermore, there are seasonal spikes in activity for Michigan HVAC workers during summers and winters, and these professionals may be called upon to work evenings, weekends, or holidays to meet client demand.

There are HVAC opportunities available across all of the main job-hunting websites such as CareerBuilder, LinkedIn, and others. As proof of point, Indeed (June 2025) posted more than 500 openings for HVAC workers.

Michigan HVAC Technician Salary Data

According to the Bureau of Labor Statistics (May 2024), there were 396,870 HVAC workers around the country with an average annual salary (annual mean wage) of $62,690. Interestingly, Michigan HVAC workers boasted roughly the same mean annual salary ($61,120) despite living in one of the most affordable states in the US.

Following are the more detailed salary percentiles for HVAC professionals nationwide as compared to Michigan (BLS May 2024)—the latest data available as of June 2025:

	United States	Michigan
Number of HVAC professionals employed	396,870	13,720
Annual mean wage	$62,690	$61,120
10th percentile	$39,130	$39,560

75th percentile	$74,820	$74,460
90th percentile	$91,020	$84,070

According to another source of data, the national figures were slightly different, PayScale (June 2025), which relies on self-reported salaries. Among the HVAC workers reporting their annual salaries, Payscale found these percentiles:

10th percentile: $35,000
50th percentile (median): $54,545
90th percentile: $94,000

As with any salary projections, considering the cost of living is also important. As such, the Missouri Economic Research and Information Center (MERIC 2025) found that Michigan had the 9th lowest cost of living in the United States.

Michigan HVAC Certification & Licensing

To work as an HVAC technician, mechanic, or installer in Michigan, getting the proper credentialing is essential. One mandatory national certification for anyone who works with refrigerants is the EPA Section 608 Certification. Four subtypes vary by equipment: type I (small appliances), type II (high-pressure refrigerants), type III (low-pressure refrigerants), and type IV (universal).

Additionally, many job postings for HVAC techs in MI call for three to five years of experience in the field and a competency-based certification. These credentials are available through various organizations such as the Refrigeration Service Engineers Society (RSES), North American Technician Excellence (NATE), and HVAC Excellence.

To learn about these credentialing entities in-depth, check out the HVAC certification page.

Finally, there is a required state credential for this profession. In Michigan, HVAC technicians must have a mechanical contractor’s license from the MI Department of Licensing and Regulatory Affairs (LARA). To qualify for the MI mechanical contractor’s license, candidates must have:

At least three years of experience (6,000 hours) in each of the work classifications for which he or she is applying (e.g., hydronic heating & cooling; HVAC equipment; refrigeration; ductwork, etc.); one year of which can be from an educational program
Detailed application with all qualifying work performed
Application fee and exam fee
Passing score (at least 70 percent) on an exam

The MI mechanical contractor’s license exam comprises written tests for each work classification sought and 20 questions on general laws & rules, the construction code, and basic safety rules. Permits and licenses are not required to install portable equipment, self-contained refrigeration systems, or window-mounted air conditioners.

Finally, five types of specialty licenses are available for those in MI with more advanced experience in the following areas: solar, solid fuel, LP distribution piping, gas piping, and gas piping & venting.
