HVAC Training Schools & Certification in Missouri

In the Show-Me State with its balmy summers and cool winters, there is a thriving demand for skilled professionals in heating, ventilation, air conditioning, and refrigeration (HVAC-R). In this relatively high-paying industry, there is an array of Missouri-based trade associations supporting workers in this field.

For example, the Missouri Plumbing-Heating-Cooling Contractors was incorporated in 1993 and represents 123 licensed contractor firms across the eastern region of Missouri (MO). The group offers educational programs to fulfill varying municipal licensing requirements, a monthly newsletter, a lending library, legislative advocacy, networking events, and group discounts for some services.

Two other organizations of note are the Eastern Missouri Mechanical Contractors Association, which provides a state-of-the-art training center, and the Mechanical Contractors Association of Kansas City (MCA-KC), which has training events, labor relations resources, and legal advocacy at the local and federal levels for issues affecting the industry.

HVAC installers and technicians in Missouri have varied responsibilities in their profession such as laying electrical wiring and pipes; repairing or maintaining system components (e.g., motors, humidifiers, hermetic compressors, filters, fans, controls, split systems, water pumps, economizers, etc.); calculating heat loads and losses; soldering and brazing parts; keeping detailed customer service records; engaging in ongoing training; performing all HVAC work to manufacturer specifications; keeping active municipal credentialing (as necessary, in areas such as Kansas City); being fluent in versatile system types (e.g., oil burning, gas, geothermal); and making recommendations to clients to improve the energy-efficiency or cost-effectiveness of systems.

While some of these professionals focus on one point-of-entry (e.g., installation, maintenance, etc.) or a type of equipment (e.g., commercial refrigerators, oil-burning furnaces), others may be generalist workers capable of servicing a range of equipment types.

It’s important to add that as of August 2024, there wasn’t a specific state license required, but local requirements on permitting vary by municipality, a variable discussed in the licensing section below. Also, all workers nationwide who handle refrigerants must get the EPA Section 608 certification, the sole nationally mandatory credential in this field.

This guide covers the available accredited HVAC training schools in MO, as well as the growth projections in the industry, salary prospects, and local licensing procedures.

Occupational Demand for HVAC Technicians in Missouri

As mentioned in the introduction, HVAC is a high-growth industry in Missouri and beyond. In fact, the Bureau of Labor Statistics (BLS 2024) predicted a 6 percent increase in openings in this field nationwide between 2022 and 2032, faster than the average growth anticipated across all occupations (3 percent) during that time period. There’s evidence that Missouri is predicted to need new technicians at an even faster rate. Projections Central predicts an 6.6 percent statewide increase in HVAC positions between 2022 and 2032.

Varied forces contribute to the steady stream of opportunities for MO HVAC workers. Not only do HVAC systems need to be replaced every 10 to 15 years, but since most modern structures have climate control systems, the servicing needs are steady throughout the year, even during the lower spring and fall seasons.

Furthermore, many owners of older buildings opt to upgrade or retrofit their structures with state-of-the-art HVAC equipment, and this too provides a wealth of opportunities. In areas of high rates of construction like Kansas City, there is a particular need for HVAC installation services. Additionally, the legislation continually evolves regarding the energy efficiency of systems, not to mention all clients’ desire to have the most cost-effective solutions in place.

The BLS (2024) notes that HVAC workers incur one of the highest rates of injury and illness among American professions for several reasons: these skilled professionals may be expected to lift heavy equipment, deal with refrigerants, travel to job sites in all weather conditions, and occasionally work in cramped conditions. All of these features of the job can lead to a higher-than-average incidence of muscle strains, electric shock, frostbite, burns, and other work-related complications. As long as HVAC professionals in MO don proper safety equipment and have rigorous training before completing projects in the field, these risks can generally be kept to a minimum.

As proof of the booming industry in HVAC, Indeed (August 2024) had 300+ relevant HVAC openings in MO, including positions with Nextech, Air Comfort Services, Inc., Executive Hills Management, Inc., Missouri State University, Howell Commercial Refrigeration, and more. Monster (August 2024) had additional HVAC openings in MO with varied employers such as Sunset Rentals, Six Flags St Louis, and Johnson Controls Internations to name a few.

Missouri HVAC Salaries – How Much do HVAC Workers Make?

Not only is HVAC a high-growth profession, it is also relatively lucrative, especially for a profession requiring only one to two years of postsecondary training.

According to the Bureau of Labor Statistics (May 2023), there were 397,450 HVAC mechanics and installers nationwide with an average annual salary (annual mean wage) of $59,620, and 8,840 HVAC mechanics and installers in Missouri with an average annual salary (annual mean wage) of $62,530. In more detail, here were the salary percentiles of HVAC professionals across the US and in Missouri specifically:

	United States	Missouri
Number of HVAC Professionals Employed	397,450	8,840
Annual Mean Wage	$59,620	$62,530
10th Percentile	$37,270	$35,360
25th Percentile	$46,550	$46,470
50th Percentile (Median)	$57,300	$57,860
75th Percentile	$71,120	$77,050
90th Percentile	$84,250	$90,040

Salary figures do vary slightly by the source of data. Payscale (2024)—an aggregator of self-reported salaries—found the following percentiles among its HVAC respondents nationwide in August 2024:

10th percentile: $36,000
50th percentile (median): $54,971
90th percentile: $84,000

The BLS figures are generally considered more reliable due to the organization’s methods of data collection and relatively high sample size. It is important to note that the Missouri Economic Research and Information Center (MERIC 2024) found Missouri was the sixth most affordable state nationwide. This low cost of living means that even average salaries will go farther in Missouri than other states.

As in any state, in Missouri salaries vary by region of employment. St. Louis, Kansas City, St. Joseph, Columbia, and Springfield enjoyed the highest salaries in the state.

HVAC Certification & Licensing in Missouri

Prior to beginning work, HVAC technicians in Missouri must ensure that they have all proper credentialing. As mentioned in the introduction, there is one mandatory certification for all people nationwide who work with refrigerants—the EPA Section 608 certification—of which there is four subtypes:

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

Other organizations which offer employment-ready credentials recognized by employers in MO include:

HVAC Excellence
North American Technician Excellence (NATE)
Refrigeration Service Engineers Society (RSES)

To learn about how to achieve credentialing through these agencies and which types of certifications are available, please visit the HVAC certifications page.

Finally, as mentioned above, there is currently no state license required to perform HVAC work in Missouri. That said, the requirements for permits vary widely between municipalities. For example, the Kansas City Planning & Development Permits Division requires HVAC contractor licensing. To qualify, candidates must submit:

A completed certificate application with reference letters
An application fee
Passing score (at least 70 percent) on the KC exam, or an equivalent

Above all, prospective HVAC workers in MO are strongly advised to check with all municipal authorities prior to beginning work, as HVAC permitting procedures vary by jurisdiction.
