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 2017) projects that job openings for HVAC installers and mechanics will swell 15 percent between 2016 and 2026, much faster than the average growth anticipated across all occupations during that time (7 percent). The expected addition of 38,700 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. And 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 (2017)—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 (2017) 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 2017).

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 2018.

HVAC, a Career on the Rise

Heating, Air Conditioning, and Refrigeration Mechanics and Installers (BLS, 2016)

As stated above, the Bureau of Labor Statistics (BLS 2017) is anticipating a 15 percent increase in openings for HVAC technicians (i.e., mechanics and installers) between 2016 and 2026. 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 buildings have inefficient energy use.

HVAC is also a relatively lucrative field, paying a mean annual wage of $48,320, with a median hourly wage of $22.07, significantly higher than the median hourly wage for all occupations, which is $17.81 (BLS 2017). Not surprisingly, HVAC professionals’ average salary fluctuates by region, industry, level of experience, and source of data.

For instance, the BLS (2016) found that the top-paying states for HVAC specialists were:

District of Columbia: $67,230 (average annual salary)
Hawaii: $66,820
Alaska: $63,620
North Dakota: $60,420
New Jersey: $58,420

The top-employing states in HVAC looks quite different (BLS 2016):

Florida: 28,700 HVAC specialists employed
California: 25,360
Texas: 24,300
New York: 15,930
Pennsylvania: 13,160

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, Missouri, and Oklahoma.

Additionally, the two top-paying municipalities for HVAC services were located in California (BLS 2016):

San Rafael, CA: $75,940 (annual average salary)
San Jose-Sunnyvale-Santa Clara, CA: $75,470
Tacoma-Lakewood, WA: $73,240
Elgin, IL: $72,800
Fargo, ND: $70,270

Overall, the BLS (2016) reported the following salary ranges for HVAC professionals across the country:

10th percentile: $28,440
25th percentile: $35,440
50th percentile (median): $45,910
75th percentile: $58,960
90th percentile: $73,350

Other data sources, however, found slightly lower figures. Payscale (2017)—a site which relies on self-reported salaries in various employment sectors—found the following salary ranges among its 838 HVAC respondents:

10th percentile: $29,000
25th percentile: $34,000
50th percentile (median): $44,000
75th percentile: $55,000
90th percentile: $70,000

HVAC Trends in 2018

As the 2018 AHR Expo in Chicago 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. HPAC Engineering (2015) reported on the increasing use of smart thermostat and integration technologies which can help save energy and cut costs by giving people the ability to manage multi-area temperatures remotely. 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’s 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. As part of the move toward increased efficiency of HVAC systems, Xcel Energy (2015) reported that there are several new green technologies on the rise, including demand-controlled ventilation; direct digital control (DDC) systems; variable air volume (VAV) systems; and variable frequency drives (VFD).

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.
