HVAC Classes

As the United States recovers from the Great Recession, there’s one field that’s been relatively impervious to the economic downturn: careers in heating, ventilation, air conditioning, and refrigeration (HVACR). In fact, the Bureau of Labor Statistics (BLS 2019) projects that job openings for HVAC installers and mechanics will swell 13 percent between 2018 and 2028, much faster than the average growth anticipated across all occupations during that time (5 percent). The expected addition of 46,300 HVAC positions is due in part to people’s enduring need for comfortable shelter in the face of increasingly erratic weather patterns. By illustration, the World Economic Forum (2017) – which has tracked the uptick in natural disasters such as Hurricane Katrina and Superstorm Sandy – correctly predicted in its annual risks report that extreme weather events and natural disasters would represent two of the three most likely risks we would face, globally, in 2017. Hurricanes Harvey and Irma, as well as the “perfect storm” Napa, Sonoma and Lake County wildfires, and the off-season winter wildfires in Los Angeles, have all borne this out. And all of these events have contributed to the need for failproof climate control in residential and commercial buildings. With burgeoning trends such as the greening of HVAC technology, the adoption of “smart” climate control systems, and the ever-changing environmental regulations set forth by local and national governments, HVAC is expected to be thriving field on into the future.

So what skills can these aspiring specialists expect to learn in HVAC classes? O*NET (2019)—a data organization partnered with the American Job Center—reports that heating and AC mechanics and installers have many responsibilities including installing, maintaining, inspecting, and repairing HVAC systems; performing tests to determine problematic components; working with sensitive systems such as water, electrical, and fuel lines; recommending upgrades to increase energy efficiency; and staying abreast of the latest technical innovations and governmental regulations for HVAC systems. Some technicians choose to further specialize, gaining skills in specific aspects of HVAC such as solar panels, green technologies, commercial refrigeration, or radiant heating systems.

Although there are varied educational paths to joining this field, O*NET (2019) found that 55 percent of responding HVAC technicians held postsecondary certificates, and 16 percent had associate’s degrees. Sixty-four percent of these professionals were industry contractors—a relatively secure segment as manufacturers and contractors may provide customers with year-round service agreements—and nine percent were self-employed (BLS 2019).

Read on to discover the employment prospects for HVAC professionals, as well as to explore HVAC classes, professional certification options, program accreditation, and trends in the HVAC industry expected in 2019.

HVAC, a Career on the Rise

Heating, Air Conditioning, and Refrigeration Mechanics and Installers (BLS, 2019)

As stated above, the Bureau of Labor Statistics (BLS 2019) is anticipating a 13 percent increase in openings for HVAC technicians (i.e., mechanics and installers) between 2018 and 2028. The wealth of opportunities for HVAC professionals has emerged for several reasons. Not only do most HVAC units have a lifespan of roughly ten years—requiring continual upkeep and maintenance—but also many businesses and homeowners stand to save money by making systems more efficient or “greener.” Energy Star (2015)—a voluntary program promoting energy use efficiency created by the US Environmental Protection Agency (EPA)—reports that the combined annual energy costs of commercial and residential properties is $400 billion, and an astounding 30 percent of all energy used in commercial buildings is wasted.

HVAC is also a relatively lucrative field, paying a median annual wage of $50,160, with a median hourly wage of $22.89, significantly higher than the median hourly wage for all occupations, which is $18.58 (BLS 2019). Not surprisingly, HVAC professionals’ average salary fluctuates by region, industry, level of experience, and source of data.

For instance, the BLS (2019) found that the top-paying states for HVAC specialists were:

District of Columbia, $33.47 per hour
Alaska, $31.87 per hour
Connecticut, $30.86 per hour
Hawaii, $29.65 per hour
Massachusetts, $28.79 per hour

The top-employing states in HVAC looks quite different (BLS 2019):

Florida, with 29,650 HVAC jobs
California, with 27,720 jobs
Texas, with 25,290 jobs
New York, with 19,160 jobs
Pennsylvania, with 15,330 jobs

It’s crucial to note that the cost of living (i.e., the purchasing power of these salaries) varies significantly by region. As proof of point, the Missouri Economic Research and Information Center (MERIC 2017) notes that the most expensive states in the country were concentrated in the west and northeast: Hawaii, District of Columbia, California, New York, and Alaska. The least expensive areas—mainly hailing from the midwest and south—were Mississippi, Arkansas, Michigan, Alabama, and Oklahoma.

Additionally, three of the 10 top-paying municipalities for HVAC services were located in California, two were in Illinois, and the rest were scattered throughout the western and northeastern United States (BLS 2019).

Overall, the BLS (2019) reported the following salary ranges for HVAC professionals across the country:

10th percentile: $29,460
25th percentile: $36,520
50th percentile (median): $47,610
75th percentile: $60,900
90th percentile: $76,230

Other data sources, however, found slightly lower figures. Payscale (2019)—a site which relies on self-reported salaries in various employment sectors—found the following salary ranges among its 4,834 HVAC respondents:

10th percentile: $30,000
50th percentile (median): $46,000
90th percentile: $72,000

HVAC Trends in 2019

As the 2020 AHR Expo in Atlanta approaches—where thousands of HVAC professionals will gather to discover new industry technologies, products, and best practices—there are six trends in the field which have caught the experts’ attention:

Smart Systems: One of the major trends in the industry is toward “smart controls” in both residential and commercial HVAC systems. The US Energy Information Administration (2017) reported that although they can improve on energy efficiency, just 3 percent of respondents to their annual survey were using a smart thermostat — but that number is expected to increase. These intelligent controls also allow people to track energy-use patterns, detect problems with components, and send diagnostics via mobile technologies to the appropriate service agency to ensure timely maintenance and repairs. The burgeoning internet of things (IoT) has been a major driver in the automation and increased distance-based control of HVAC systems.

Increased Integration and Automation: Aided in part by the increased use of “smart” HVAC technologies, the ability to control several systems seamlessly in concert is a major goal in the industry. It is no surprise that homeowners, property managers, and business operators can benefit from having one easy-to-operate interface for temperature controls. In fact, HVAC businesses are striving to improve the mobility, user-friendliness, and comprehensiveness of software that can link multiple systems together.

HVAC Goes Green: Green technology systems that pay thought to energy conservation and efficiency are on the rise. Enervise (2015) stated that the federal government’s property-assessed clean energy financing (PACE) program has contributed to the awareness of efficiency, renewable energy sources, and the greening of HVAC by empowering local governments to fund much-needed energy improvements to residential and commercial properties. Governments pay up-front for the upgrades and property owners pay these back over time. Furthermore, buildings are striving to be net zero energy use facilities (i.e., producing as much or more energy than they consume) through the use of renewables (e.g., wind, solar, geothermal, and hydraulic) and energy recovery ventilators.

Evolving Regulations: Federal and local governments are continually changing the standards of energy use, product labeling, building codes, and tax credits, in effect rewarding the use of more efficient HVAC technologies. The US government’s Office of Energy Efficiency and Renewable Energy (EERE) strives to develop innovative technologies to promote energy efficiency in manufacturing plants, HVAC products, new homes, and buildings. Legislation such as the Energy Policy Act (2005), as well as changes to the annual fuel utilization efficiency (AFUE) standards and seasonal energy efficiency ratio (SEER) are applied differentially across states, affecting building codes and the type of HVAC equipment available.

Proprietary Controls: Although there’s a general move toward increased integration of HVAC systems, in order to preserve market dominance, some companies continue to create proprietary components which do not integrate seamlessly with other company’s products. HPAC Engineering (2015)—using figures from an IHS, Inc. (2014) study—reported that 14.2 of worldwide controllers used proprietary controls.
