How to Become an HVAC Technician

Most people do not spend a lot of time thinking about their heating system or air-conditioning units. When a building or room is at the perfect temperature, almost no one notices. But when one of these systems breaks down, an HVAC technician is the first person to call.

HVAC technicians are trained to install, repair, and replace HVAC systems. The acronym stands for heating, ventilation, and air conditioning. Some technicians and training programs prefer to use the acronym HVAC/R because repairing refrigeration systems can also be a crucial part of the job. HVAC technicians may find a place working on construction sites, as a part of a general contractor’s team, or as an independent repair person.

An HVAC technician is different from a general contractor or any other specialties in the construction industry. “HVAC technician” is an umbrella term for other HVAC specialties. Since HVAC technicians are trained in all HVAC systems generally, some technicians become much more specialized in the types of work they take on as their career progresses. For instance, an HVAC installer may work for contractors who build new homes or buildings and specialize only in installing new systems rather than repairs. Some HVAC techs also specialize in air conditioning or refrigeration, steering away from heating and ventilation.

Check out this comprehensive guide to becoming an HVAC technician below.

Skills & Personality Traits of HVAC Technicians

There are a few important qualifications to consider when becoming an HVAC technician. First and foremost, HVAC technicians must be thoroughly educated in the specifics of HVAC systems to perform repairs. This requires mechanical skills, a detail-oriented personality, and the physical fitness necessary to lift, move, and repair large equipment.

While the technical skills needed to complete HVAC repairs are essential, certain personality traits make success more likely for a prospective HVAC technician.

HVAC technicians must be reliable, as many are called to jobs at odd hours, including weekends. Furthermore, the most successful HVAC technicians can explain the intricacies of an HVAC system to a customer who may not be familiar with the specifics of their building’s system.

In addition to technical knowledge and manual skills, HVAC technicians may also need to sell service contracts to their customers. In that case, HVAC technicians must be able to convince the customer that the repairs are indeed necessary. To be a successful HVAC technician, one must have strong interpersonal skills and be able to communicate clearly and directly.

Role Requirements for HVAC Professionals

Technical training and education are both key requirements for becoming an HVAC tech.

Before beginning work, most HVAC technicians have at least some specialized training. Today, most HVAC technicians begin by taking courses at a technical school or community college. Shorter programs may last only six months and result in an HVAC technician certificate, while longer programs can last up to two years and result in an associate degree. HVAC technicians can begin to prepare for this type of training in high school by taking courses in math, physics, and shop.

Once formal training is completed, some states require professional licensing before an HVAC technician can begin work. To research local credentialing requirements, reach out to state HVAC licensing authorities.

Some licenses, however, do transcend geography. Namely, the Environmental Protection Agency (EPA) requires that any technician working with refrigerants (such as CFCs and HCFCs) be properly trained to handle and dispose of these hazardous chemicals. HVAC technicians can become certified in small appliances, low-pressure systems, high-pressure systems, or can obtain a universal certification that qualifies them to work with all refrigerant systems. Several third-party companies offer the tests for this type of licensing and can be completed online.

Career, Education, and Certification to Become an HVAC Technician

Overall, the demand for HVAC technicians is growing. According to the Bureau of Labor Statistics (BLS 2024), the need for all HVAC technicians is expected to increase by 9 percent between 2023 and 2033, which represents approximately 40,100 new job openings during that decade. However, this is more than double than the average expected growth for all occupations during the same decade (4 percent).

While there are numerous ways to become a certified HVAC technician, some choose to gain experience by obtaining on-the-job training or by participating in an apprenticeship. Others might enroll in accredited HVAC programs to better prepare for the competitive job market.

According to the U.S. Department of Labor, HVAC technicians must have training in vocational schools, related on-the-job experience, or an associate’s degree. (ONET Online 2024).

After some measure of formal education, further on-the-job training is generally required. Sometimes this can take the form of an apprenticeship with an experienced HVAC technician. Other HVAC technicians will move directly from school to entry-level positions.

Paths to becoming an HVAC technician often diverge after the first one to three years of work. At that point, there are several options for exams and certifications that can lead to more specialized work.

While there are no national associations that an HVAC technician must join, many offer career support and certifications. One of the most prolific testing organizations, North American Technician Excellence (NATE), offers Industry Competency Exams (also known as ICE) in installation and service specialties. These exams are supported and recognized by other HVAC organizations, including the Air-conditioning, Heating, and Refrigeration Institute (AHRI), the Air Conditioning Contractors of America (ACCA), and the Heating, Air-conditioning, and Refrigeration Distributors International (HARDI).

Advanced HVAC certifications can be attractive to potential employers and clients, so many HVAC technicians do decide to pursue them, but they are not required. Sometimes an employer may require further education for job advancement. For instance, an HVAC technician with no specialty working for a construction company may need to obtain certification in the HVAC installation track to move forward and supervise new buildings. Ultimately, further education and certification are the best ways to progress in a career as an HVAC technician. Coupled with ongoing technical experience, the path to becoming an HVAC technician can be varied and promising.

HVAC Technician Salary

According to the Bureau of Labor Statistics (May 2023), HVAC professionals earn relatively competitive salaries, particularly for positions that may require just two years of post-secondary training. BLS (May 2023) reported that there were 397,450 HVAC mechanics and installers nationwide with an average annual salary (annual mean wage) of $59,620. The table below is a detailed overview of the national salaries of HVAC professionals—the latest data available as of January 2025.

	United States
Number of HVAC professionals employed	397,450
Annual mean wage	$59,620
10th percentile	$37,270
25th percentile	$46,550
50th percentile (median)	$57,300
75th percentile	$71,120
90th percentile	$84,250

Geographic location can also play a huge part in how much workers can earn due to cost of living factors. HVAC technician salaries in the U.S. are highest in the District of Columbia, where HVAC technicians make an average salary of $77,970, followed by Alaska, Massachusetts, Hawaii, and Washington. In states where the cost of living is much lower, such as West Virginia, Oklahoma, Kansas, Alabama, and Mississippi, AC technicians make much less, with Mississippi technicians making an average of just $47,420. Those new to this profession will likely make closer to the lower end of the spectrum, while more experienced technicians will make more.

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

10th percentile: $36,000
50th percentile (median): $55,431
90th percentile: $84,000

Over time, it will be dedication and experience to the craft that will determine whether an HVAC technician continues to move up in the ranks in terms of both responsibility and salary.

Steps to Becoming an HVAC Technician

Here is an example of a possible path to becoming an HVAC technician:

Step 1: Earn a high school diploma or GED (four years).

Aspiring HVAC technicians should have strong chemistry, physics, and other physical sciences skills. Additionally, competitive candidates may also have volunteer or work experience assisting HVAC technicians.

Step 2a: Join and complete an accredited HVAC program (six months to two years).

Candidates may apply for a certificate, associate, or bachelor’s degree program that features coursework in HVAC system design; refrigeration; energy management; load calculations, industry code standards; ductwork and piping systems; and air quality and conditioning. Prospective HVAC technicians in these programs learn HVAC theory and practice, and may also work with HVAC technicians for hands-on training.

Two institutions offering accreditation for HVAC classes are HVAC Excellence and Partnership for Air-Conditioning, Heating, Refrigeration Accreditation (PAHRA). The accreditation process establishes academic standards and recognizes programs that meet or exceed the criteria. Learn more about accredited programs in different states by visiting the HVAC schools page.

Step 2b: Complete an apprenticeship (optional, three to five years).

Some HVAC technicians choose to acquire their skills through an apprenticeship, where they perform 2,000 hours of hands-on HVAC training annually and 144 hours of technical education.

Some organizations provide HVAC apprenticeships, including the Air Conditioning Contractors of America, Inc., the Associated Builders and Contractors, and the US Department of Labor’s Apprenticeship USA program. HVAC apprenticeships are typically paid positions; the exact salary will vary based on experience, location, and employer.

Step 3: Become an HVAC technician and work in the field (one to two years).

Before becoming a certified HVAC technician, it may be advisable to get some empirical professional-level (i.e., beyond apprentice-level) experience. Please note that there are some “job-ready” HVAC programs that may bypass this step. As described above, one may obtain an entry-level HVAC technician position without professional certification, although technicians working with regulated refrigerants must have a basic EPA 608 certification.

Step 4: Achieve professional certification (timeline varies).

While HVAC technician requirements vary by state, there are some popular certifications in this industry such as those offered by North American Technician Excellence (NATE), the Refrigerating Engineers and Technicians Association (RETA), and HVAC Excellence (partnered with the Esco Group).

For instance, NATE offers several specialty certifications (e.g., air distribution, HVAC efficiency analyst, HVAC performance verifier), whereas HVAC Excellence offers more generalized certification exams for air conditioning, light commercial air conditioning, and basic refrigeration and charging procedures. In addition, RETA offers two American National Standards Institute accredited certifications, including a certified assistant refrigeration operator (CARO) and a certified industrial refrigeration operator (CIRO).
