HVAC Career Information

T he world outdoors is often an uncomfortable place. Weather changes can bring precipitation, blustery winds, and extreme temperatures. That's why we turn to the shelter of indoor spaces. We rely on climate-controlled environments to carry out our lives comfortably and effectively. But it takes much more than just a few walls, a roof, and insulation to make it all happen. So, what is HVAC?

What is HVAC and HVAC/R?

HVAC stands for heating, ventilation, and air conditioning. The HVAC systems in our homes, offices, shopping malls, and other buildings allow us to live inside without too much concern for what's happening outside. But HVAC goes beyond the regulation of indoor temperatures. When such systems are properly installed and maintained, they contribute to better airflow and healthier indoor air quality, which is especially important for people with allergies, asthma, or other medical issues.

In addition to heating, ventilation, and air conditioning, there is another type of climate-control technology that is crucial to modern life. The "R" in HVAC/R stands for refrigeration. The storage and transport of perishable foods, medicines, and other items we may take for granted is made possible by today's commercial refrigeration systems. (Side note: Don't be confused by the different ways in which the "R" is added to HVAC. The subtle variations you might encounter—HVAC&R, HVAC/R, HVACR, HVAC-R, or HVAC R—all mean the same thing.)

Advances in HVAC technology are making the heating and cooling of new and retrofitted buildings more and more energy efficient. Refrigerants are being developed and used that are more environmentally friendly. And technologies such as hydronics (water-based heating), geothermal, and solar-powered heating and cooling are turning the HVAC profession into one with a growing number of "green" jobs.

HVAC systems are installed and serviced by HVAC technicians (who are sometimes known as HVAC mechanics or HVAC installers).

What Does an HVAC Technician Do?

The work of an HVAC technician can be rather varied. From installation to routine maintenance to repair, the many duties of a professional in the heating, ventilation, and air conditioning industry often add up to working days full of diverse activities. However, a lot depends on whether or not an HVAC technician chooses to specialize in working with a particular type of equipment (i.e., residential, light commercial, or commercial/industrial) in either the installation or service side of the business.

So, depending on their specialty, level of knowledge, and arsenal of skills, HVAC technicians carry out tasks that can include:

• Installing furnaces, heat pumps, and air conditioning units
• Installing the ductwork that carries treated air throughout a building
• Following blueprints and specifications used in the installation of HVAC systems, including air ducts, vents, pumps, water and fuel supply lines, and other components
• Connecting electrical wiring and controls
• Performing routine maintenance on a variety of HVAC equipment, such as checking for leaks, adjusting blowers and burners, and checking nozzles, thermostats, electrical circuits, controls, and other components
• Diagnosing and repairing problems that are found within any part of an HVAC system
• Adjusting the controls of an HVAC system and recommending appropriate settings
• Testing the performance of a furnace, heat pump, air conditioning unit or other piece of HVAC equipment to ensure that it operates at peak efficiency
• Using carbon dioxide and carbon monoxide testers to make sure that a customer's equipment operates safely
• Selling service contracts or replacement equipment to customers

HVAC/R technicians, sometimes known as refrigeration mechanics, install and service commercial or industrial refrigeration systems. In addition to some of the tasks above, HVAC/R technicians have duties that can include:

• Charging refrigeration systems with the proper refrigerant
• Conserving, recovering, and recycling refrigerants for reuse or ensuring that they are disposed of properly since their release can be very harmful to the environment
• Venting refrigerant into the appropriate cylinders

To perform their duties, HVAC and HVAC/R technicians use a large variety of special tools (sometimes numbering in the dozens) such as:

• Pressure gauges
• Acetylene torches
• Voltmeters, ohmmeters, and multimeters
• Combustion analyzers
• Soldering and brazing equipment
• Pipe cutters
• Gas detectors
• Micron gauges
• Tap and die sets

Where Can HVAC Technicians Work?

Whether they specialize in installing or servicing residential, commercial, or industrial equipment (or all three), HVAC technicians perform their work on-site in a wide variety of settings. Any building that utilizes climate-control equipment will see multiple visits by HVAC technicians over the course of its lifetime. Such buildings can include:

• Homes
• Schools
• Stores
• Restaurants
• Offices
• Hospitals
• Factories
• Airports

Most HVAC technicians work for independent service contractors. However, employment can also be found with:

• Direct-selling retail establishments (e.g., HVAC equipment dealers)
• Repair shops for commercial or industrial equipment and machinery
• Merchant wholesalers of heating equipment and supplies

What is the Typical Salary of an HVAC Technician?

The typical salary of an HVAC technician depends on many factors such as the type of HVAC job, employer location, level of experience, and whether or not a union is involved. When it comes to HVAC, salary is usually implemented in the form of hourly wages. Most HVAC technicians, regardless of their training, begin their careers at a relatively low rate of pay, but their wages rise gradually as they increase their skills, knowledge, and experience.

So, what are some average HVAC salaries? Based on national estimates, yearly wages for HVAC and HVAC/R technicians break down this way: *

• The bottom 10 percent earn $26,490 or less.
• Median wages (50th percentile) are $42,530.
• The top 10 percent earn $66,930 or more.

The pay scales of similar employers, even within the same city, can sometimes vary dramatically. HVAC/R technicians that install and service commercial or industrial systems generally get paid the most. Unionized employers also tend to have much higher wages than non-unionized ones. However, you can expect a large chunk of your wages from any union job to go toward paying for union fees, insurance, and other benefits.

Many HVAC technicians maximize their income by working longer hours during peak seasons (summer and/or winter). Additional wages can also come, in some cases, from earning commissions on the sale of new equipment or service contracts.

Are There Any Downsides to Working in the HVAC Trade?

For the people who turn it into a long-term career, HVAC is a lifestyle. Many HVAC technicians reap a great deal of personal satisfaction from their work. But, like any occupation, the field of heating, ventilation, and air conditioning has its upsides and downsides. It's not a career for everybody. You've got to be 100 percent committed in order to succeed.

Here are some of the possible drawbacks of being an HVAC or HVAC/R technician:

• Physical hazards—It can be grueling and hard on your body. Installing or servicing HVAC systems often requires heavy lifting, crouching, and kneeling—including in tight places like attics and crawl spaces. Other physical hazards also exist such as the potential for cuts, scrapes, electrical shock, burns, or muscle strain. And, although rare, working with refrigerants without appropriate safety equipment can result in injuries like frostbite, skin damage, or even blindness.
• Uncomfortable working conditions—It frequently involves working outdoors in bad weather or extreme temperatures (hot and cold).
• Mental fatigue—In addition to being physically demanding, HVAC work can also be mentally tiring. That's because you must remain alert and focused in order to solve problems and avoid injury or costly mistakes. Plus, no matter how experienced you are, there is always a lot to learn. HVAC technology changes quickly, so being an HVAC technician requires staying on top of the latest developments and adding that knowledge to what you've already learned about older systems that are still in use. That makes the job sometimes feel overwhelming. As HVAC technology improves, much of it is also becoming more and more technically challenging to work on.
• Fluctuating work hours—Employment in the HVAC trade can sometimes be subject to seasonal fluctuations, particularly for technicians without much experience. It is common for many HVAC service technicians to work very long hours during peak seasons (summer and winter) followed by a reduction in hours (often less than full time) during the slower seasons. The peak seasons can be extra difficult if you have a family since working overtime and being on call at all hours (including weekends) can mean you're not able to spend as much quality time with those you care about. On the other hand, slow weeks are also inevitable, so you have to know how to account for the ups and downs in your personal finances.
• Irritable customers—Since many service calls happen when customers are in distress over failing heating or cooling equipment during extreme weather, HVAC technicians sometimes must deal directly with people who are cranky and impatient. Tempers are heightened when a problem can't be fixed right away because a part needs to be ordered.
• Delayed gratification—It takes time—usually at least five years—to develop the skills that enable you to begin making what are considered good wages in the HVAC industry. As a new technician, you should expect the starting pay to be lower than what you might be hoping for. You have to be willing to stick it out and learn everything you can in the meantime.

What are the Good Things About Working in HVAC?

The downsides of being an HVAC technician are balanced—and some might even say overcome—by the many positive attributes of the HVAC trade. Here are a few of them:

• A sense of accomplishment—It can be intensely rewarding to fix problematic equipment or install new systems since it means that your hard work directly impacts the ability of people to feel comfortable in their environments. You have the chance to make someone's day if they were freezing (or sweating) prior to your arrival. Plus, looking back on a job well done often leads to a great feeling of personal satisfaction, regardless of how difficult it might have been.
• Built-in exercise for mind and body—Despite the occupational hazards, being an HVAC technician can help you stay in shape—physically and mentally.
• Variety—Every day is bound to be somewhat different. You won't be stuck in an office. Instead, you'll get to solve a variety of problems and meet new people. And the fast pace of busy times helps the work days pass quickly.
• Pride—Because HVAC technicians can impact the well-being of people and the environment, they often feel a great sense of personal responsibility and pride of purpose.
• Stimulation—Opportunities for learning something new happen on a frequent basis, which means boredom is rare. As the HVAC industry moves closer and closer toward full computer automation for heating, ventilation, and air conditioning systems, the chance to develop advanced skills and knowledge also increases.
• Long-term stability—Once you've established yourself in the trade, there is great potential for making good money. And the job security can also be good. This is particularly true when you consider that HVAC skills are portable, and the work must be performed on location, which means that HVAC jobs are not subject to foreign outsourcing.

What Personal Characteristics Do I Need for an HVAC Career?

People who succeed as HVAC technicians possess key traits that enable them to handle the challenges of the occupation while taking advantage of the benefits. It's important to keep in mind that those who find long-term success and satisfaction in the HVAC trade generally possess the following characteristics:

• A strong desire to help other people
• Dependability
• A sense of craftsmanship and pride in their work (no cutting corners)
• Physical and mental toughness
• Honesty
• A courteous and respectful attitude
• Pride in their appearance
• An aptitude for mechanical, hands-on work
• Strong interpersonal skills
• Common sense
• The ability and willingness to learn
• Determination and a strong work ethic
• An interest in the science behind HVAC technology
• Good problem-solving abilities
• Adaptability

How Do You Become an HVAC Technician?

There is more than one path to establishing a career in heating, ventilation, and air conditioning. When asking, "How do you become an HVAC technician?" it is important to consider that there are essentially four different ways to begin going about it:

1. Obtaining formal HVAC training from a high school program or post-secondary school
2. Entering a formal apprenticeship program for your training
3. Joining the Armed Forces and receiving military HVAC training
4. Pursuing an entry-level HVAC position without any formal training and hoping that you find an employer willing to teach you everything informally on the job (an increasingly rare circumstance)

Each option has its advantages and disadvantages. However, most employers generally consider formal training a must before they will even consider you for an open position.

Here are some things to consider about post-secondary training at an HVAC school:

• Most HVAC training programs at technical and trade schools take between six months and two years to complete.
• Programs that last a year or less generally award a diploma or certificate of completion. Those that last two years usually award an associate's degree.
• Shorter certificate or diploma programs are often designed only to teach students the basics of one of the three main areas of HVAC/R: (1) residential heating and air conditioning, (2) light commercial heating and air conditioning, or (3) commercial refrigeration.
• Most well-respected HVAC training schools offer programs that are accredited by at least one of the following agencies: HVAC Excellence, the National Center for Construction Education and Research (NCCER), or the Partnership for Air-Conditioning, Heating, and Refrigeration Accreditation (PAHRA).
• Taking the right courses in high school can help you better prepare for HVAC school. These include subjects such as mechanical drawing, basic electronics, math, computer science, and applied physics and chemistry. It can also be beneficial to gain some basic knowledge of electrical and plumbing work.
• HVAC schools are designed to give you a head start in the acquisition of your skills, but it will likely take a few years of working experience as an assistant HVAC technician after you graduate before anyone will begin to think of you as proficient.

Another popular and advantageous way to receive formal training is through an apprenticeship. Here is what you should know about HVAC apprenticeships:

• In general, apprenticeship opportunities pop up only periodically depending on the needs of employers, both unionized and non-unionized.
• Apprenticeships are often a pathway to national certification in the HVAC industry, and they can even allow you to earn college credits.
• In order to reap all of the benefits of a formal HVAC apprenticeship, you'll want to find an apprenticeship program that is registered with the Office of Apprenticeship, which is part of the U.S. Department of Labor's Employment and Training Administration.
• Most apprenticeships allow you to earn a wage while you learn. And, if you are part of a registered apprenticeship program, your paycheck is guaranteed to increase over time. Unionized apprenticeships offer the additional advantages of working under the protection of a union contract and, usually, receiving insurance and pension benefits.
• Apprenticeships usually last four to five years, and they include both classroom instruction and hands-on training on the job. After completing a five-year registered apprenticeship, you can become a journeyman in the HVAC field.
• The organizations with the most HVAC apprenticeship opportunities include, in no particular order: (1) Air-Conditioning Contractors of America (ACCA), (2) Mechanical Contractors of America (MCAA), (3) Plumbing-Heating-Cooling Contractors (PHCC), (4) Sheet Metal Workers' International Association (SMWIA), (5) Associated Builders and Contractors (ABC), and (6) United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States and Canada (UA).
• Apprenticeship openings are often highly competitive. Plus, you must meet the minimum requirements of whatever apprenticeship program you are applying for. Organizations that offer or coordinate apprenticeships in HVAC often look for candidates that have at least a high school diploma (or equivalent), good math and reading skills, above-average manual dexterity and hand-eye coordination, strong mechanical aptitude, patience, dependability, the ability to get along well with other people, and a desire to do whatever it takes to learn the trade. As part of the application process, you may also be required to take aptitude tests and attend multiple interviews.
• Completing an HVAC program at a technical college or trade school can sometimes give you a leg up on the competition when applying for a registered apprenticeship.

Regardless of how you get your HVAC training, there are a number of other things to keep in mind about the HVAC trade and finding work in it. Consider the following points:

• Many employers look for HVAC professionals with at least two to five years of on-the-job experience. Schooling alone, while beneficial, is often not enough—particularly for openings at larger companies.
• In order to break into the trade and get the experience you need, you might have to spend a few years working for a smaller HVAC company at a lower wage than you might be expecting. The more you are willing to swallow your pride and do whatever is necessary to gain experience, the more opportunities you will have at the beginning of your career.
• In many regions, you are more likely to land your first HVAC job during a peak season (summer or winter) since that is when demand for HVAC workers increases.
• Employers want workers who will stick around for the long haul. That's why many of them prefer to hire people who've completed a formal HVAC program. Completing an HVAC education is a sign that you aren't just looking for a temporary job but, rather, have put your heart into making HVAC your career.
• As you seek to gain experience early in your career, it's best to go for variety, if possible, in the type of HVAC work you do. Some people in the trade get "stuck" in just one particular area (such as installation) and find it difficult later on if they wish to move into a different HVAC specialty that they might enjoy better.
• It pays to be assertive and proactive, especially when it comes to increasing your HVAC knowledge. You'll have better job security and advancement opportunities if you can become the "go-to" person for technical information and troubleshooting know-how about the equipment your employer sells and services. As you begin your career, it is essential to ask a lot of questions, pay close attention, and study, study, study. And, as you continue your career, the need to learn never stops. There will always be more to know.
• Like in any other trade, the better you are at your job, the more quickly you can climb the HVAC career ladder.
• It is impossible to learn everything you need to know in two years or less. So, although trade school can give you a great head start on the fundamentals, you should expect to begin your HVAC career in a "helper" or apprentice role as you continue to learn. It generally takes at least five years of on-the-job experience before you're ready to work on your own.
• Since demand for HVAC technicians can sometimes be prone to seasonal fluctuations, it is important to learn how to manage your money in a way that allows you to ride out any downtimes comfortably.
• Long-term success as an HVAC technician hinges a great deal upon your reputation. So it's important to develop a courteous and respectful attitude early on, to never cut corners, and to let the quality of work you perform speak for itself.
• Persistence and enthusiasm are the biggest keys to landing your first job in HVAC. Employers look for people who are willing to commit to hard work. You can improve your chances of finding employment by always acting polite and professional, following up repeatedly with the people in charge of hiring, and demonstrating to them that you're not an arrogant "know-it-all" but are, instead, humble and ready to learn and take on all of the challenges inherent to HVAC work.

How Do You Get HVAC Certification?

When asking, "How do you get HVAC certification?" it is essential to understand that some certifications are required while most others are voluntary. Even voluntary certifications, however, can help you advance in your HVAC career since most employers like to see official acknowledgment of your competencies.

But knowing how to obtain HVAC certification is just one aspect of this issue. You also need to understand what it all means. Here are the most important things to remember:

• Regardless of which area of HVAC/R you choose to work in, you will be required to obtain at least one type of certification from the U.S. Environmental Protection Agency (EPA). Section 608 of the Clean Air Act of 1990 requires anyone who services equipment that uses specific refrigerants to take a test to prove that they know how to properly handle, recycle, and dispose of materials that can damage the ozone layer.
• EPA Section 608 certification is broken down into four types depending on the kind of equipment you will be working with: (1) Type I for small appliances, (2) Type II for very high-pressure appliances, (3) Type III for low-pressure appliances, and (4) Universal for all types of HVAC/R equipment.
• HVAC students enrolled in formal training are often required to take the EPA Section 608 Universal certification test as part of their program.
• Although not required by the EPA, R-410A certification covers an especially dangerous type of refrigerant in greater detail than what is found in the EPA Section 608 test. R-410A refrigerant is used at a much higher vapor pressure than other refrigerants and, therefore, requires different tools, equipment, and safety standards. R-410A is increasingly replacing some of the older ozone-damaging refrigerants that are being phased out.
• Other types of professional HVAC certifications are designed to verify the real-world skills and working knowledge of HVAC and HVAC/R technicians who've had at least a year or two of on-the-job experience. Certification is offered by independent organizations in many different specialty areas such as residential and commercial air conditioning, heat pump service and installation, gas heat, electric heat, oil furnaces, hydronics, air distribution, and commercial refrigeration.
• The two most recognized providers of professional-level certifications in the American HVAC/R industry are (1) HVAC Excellence and (2) North American Technician Excellence (NATE). Obtaining certification from these organizations involves meeting any necessary prerequisites and then passing written exams. You can also obtain your EPA Section 608 certification through such providers.
• A certificate of completion (or diploma) from a formal HVAC training school is NOT the same thing as professional-level certification from organizations like HVAC Excellence or NATE.

How Long Do HVAC Classes Take?

Formal HVAC programs at technical colleges and trade schools vary in length. A lot depends on the type of credential you're after and how in-depth you want your schooling to be. So, how long do HVAC classes take?

HVAC programs that award certificates or diplomas typically last one year or less. Some take as little as about 18 weeks to complete. With these shorter programs, you often must choose to study just one of three specific areas: (1) light commercial air conditioning and heating, (2) residential air conditioning and heating, or (3) commercial refrigeration.

Associate degree programs in HVAC/R technology, on the other hand, are designed to last two years and are often more comprehensive.

How Much Does HVAC School Cost?

The cost of HVAC schooling varies significantly depending on where you go to school and whether you choose to pursue a certificate or associate degree. So, how much does HVAC school cost?

Basic program costs, including tuition, can range from as little as $2,000 or less to as much as $35,000 or more. The more expensive programs sometimes have a wider range of HVAC equipment and tools in their labs for better hands-on learning, although it is best to tour any school you are considering and check out their facilities to make sure you'll be getting good value for your money. Books and supplies are sometimes an extra expense and can cost as much as $4,500 depending on the program.

Financial aid in the form of loans and grants are frequently available from the federal government for those who qualify. And some states offer financial assistance through their own retraining programs for unemployed workers.

What Can I Expect to Learn in My HVAC Training?

HVAC schools are set up to teach the fundamentals of what you need to know to begin working as an HVAC technician at the entry level. Ultimately, HVAC involves learning at least the basics of about five different trades competently, including electrical work, plumbing, welding, pipefitting, and sheet metal.

HVAC education programs vary in their curriculum, but the ones that are accredited by an industry-recognized organization generally share a number of common elements. Three of the biggest accrediting bodies for HVAC training are (1) HVAC Excellence, (2) the Partnership for Air-Conditioning, Heating, and Refrigeration Accreditation, and (3) the National Center for Construction Education and Research.

Most HVAC programs combine classroom study with hands-on training. Depending on the school and program you choose, you can expect the curriculum to include subjects such as:

• Electricity
• Electric, gas, and oil heat
• Residential and light commercial air conditioning
• Heat pumps
• Refrigeration
• Basic electronics
• Math
• Piping
• Soldering and brazing
• Venting and duct systems
• Interpreting mechanical drawings and diagrams
• Components of HVAC systems
• General HVAC theory
• Thermostats
• Airflow and indoor air quality
• Heating fuels
• Refrigerant types and refrigerant oils
• Installation and service
• Troubleshooting and problem solving
• Building codes and requirements
• Tools and test instruments
• Safety precautions and practices

Many accredited HVAC/R programs use the Industry Competency Exam (ICE) as an exit exam for students. So, depending on the program you choose, you might have to take one or more of the three different tests that are available as part of the ICE. The different testing areas are: (1) residential air conditioning and heating, (2) light commercial air conditioning and heating, and (3) commercial refrigeration.

As an HVAC Technician, Will I Need to Be Licensed?

The answer depends on where you intend to work. Licensing requirements for HVAC technicians vary greatly depending on the state or locality they work in and whether they intend to be their own boss. And some states don't have any legal requirements. In the ones that do, however, a state exam often must be passed. Plus, some states require you to have completed the equivalent of an apprenticeship program or two to five years of on-the-job HVAC experience before you can apply for a license to legally work on your own.

The content of state licensing exams also varies significantly. In some states, for example, emphasis might be placed on having an extensive knowledge of electrical codes, but, in other states, the focus might be more on HVAC-specific knowledge.

Just remember: Although your state might not require you to obtain an official license in order to perform HVAC work, the federal government will still require you to be certified in the proper handling of refrigerants. The EPA Section 608 certification exam is a written test and is administered by a variety of organizations that have been approved by the U.S. Environmental Protection Agency, including unions, building groups, trade schools, and contractor associations.

How Promising is the HVAC Job Outlook?

The HVAC job outlook is expected to be excellent for the foreseeable future. In America, employment of HVAC technicians is projected to increase by 28 percent between 2008 and 2018, which is much faster than average. **

The growing demand for HVAC and HVAC/R technicians can be attributed to a number of factors. As the nation's population grows, so does the number of buildings (residential, commercial, and industrial) that need to be fitted with climate-control systems. And the increasing complexity of new HVAC systems means an increasing possibility of their malfunction and need for servicing, which then requires skilled technicians. In addition, the growing focus on reducing energy consumption and improving indoor air quality means that more HVAC technicians are needed for analyzing the efficiency of existing systems and replacing old polluting ones with new, more efficient models.

Although experienced HVAC technicians can expect excellent job prospects, the odds of new techs landing employment are best for those who have had training through a formal apprenticeship program, through an accredited program from an HVAC school, or both. You can also increase your chances of landing a good job by becoming an expert at increasing energy efficiency and gaining a solid understanding of complex computer-controlled HVAC systems such as those found in modern high-rises.

What Kind of Advancement Opportunities Exist in the Heating, Ventilation,
and Air Conditioning (HVAC) Industry?

The HVAC industry is incredibly diverse. Most HVAC technicians begin their careers in the residential and light commercial sectors of the field. Advancement usually comes in the form of higher wages or supervisory positions. But, with advanced knowledge, a lot of experience, and the right mindset, new opportunities can arise for entering other areas of the industry, which offer new challenges.

Commercial refrigeration, for instance, is an area of high demand that requires workers with a lot of patience and specialized skills. With the right training and education, HVAC/R technicians can also specialize in areas such as solar-powered or geothermal heating and cooling, retrofitting, system testing and balancing, efficiency evaluations, or building operations with advanced computer controls. In addition, some technicians move into teaching, HVAC sales and marketing, or managing their own contracting businesses.

It is even possible to earn a bachelor's degree in HVAC engineering technology. Such a degree could allow you to become an HVAC engineer or HVAC technologist and design new systems and controls for the manufacturing, commercial, institutional, or industrial sectors.

How Do I Get Started?

One of the best ways to discover whether HVAC might be a good field for you is to talk with a few experienced HVAC technicians. See if you can schedule a time to ride along with them on some service or installation calls. Or, if you're ready to get moving now, then check out our list of HVAC schools.
