HVAC Training

HVAC schools are set up to teach what you need to know in order to begin working as a technician at the entry level. In some cases, completing college-level training can also shorten the length of an apprenticeship if you choose to go that route.

Benefits of HVAC Training

Learning from those in the know: You can get guidance from experienced instructors who understand industry-current practices and can challenge you to keep adding to your skill set.

Hands-on practice: Trade school HVAC programs often give students lots of practical experience with the types of tools and situations that technicians commonly deal with on the job. That means you can concentrate on expanding your skills without the pressure of real-world job expectations.

Professional certification: Many programs are designed to prepare students for the Section 608 certification exam that is required for any technician who handles refrigerants.

Length of Training

It typically takes eight to 24 months to complete a post-secondary program in HVAC technology.*

HVAC Program Options

Certificate or diploma programs in HVAC technology typically last one year or less, though some take up to two years.* Some shorter programs focus on one specific area, such as air conditioning technology or residential heating and cooling. They offer a quick way to enter the trade.

Associate degree programs are generally designed to last about two years.* They are similar to certificate and diploma programs but tend to offer a broader scope of training, including several general education courses that can give you a more well-rounded experience. Completing a program at this level can make you a stronger candidate for supervisory roles once you have some experience.

Apprenticeships can last up to five years.* Some companies are willing to hire apprentices and provide all the training on the job. Formal HVAC apprenticeships that consist of a mix of technical lessons and paid workplace training are often sponsored by trade associations or plumbing or sheet metal unions. You can try using the online search tool from the Department of Labor to find apprenticeships in your area.



Typical Courses

 Depending on the program you choose, you may receive instruction in subjects such as:

  • Interpretation of mechanical drawings and diagrams
  • General theories of heating, ventilation, air conditioning, and refrigeration
  • Principles of electric, gas, and oil heat
  • Airflow and indoor air quality
  • Basic electricity
  • Heating fuels
  • Heat pumps
  • Thermostats
  • Refrigerant types
  • Piping
  • Soldering and brazing
  • Venting and duct systems
  • Installation and service
  • Troubleshooting and problem solving
  • Building codes
  • Safety practices

Many HVAC programs that are accredited by an industry organization use the Industry Competency Exams (ICE) as exit tests 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.

Skills You Can Learn

You could begin learning how to:

  • Read and understand blueprints
  • Set up, troubleshoot, and maintain residential and commercial equipment and systems
  • Calculate loads in BTUs (British thermal units)
  • Braze and solder pipes and fittings
  • Connect electrical wiring
  • Handle refrigerants
  • Follow safety protocols

Licensing & Certification

Licensing and certification requirements for HVAC technicians depend on where they live, the specific types of systems they work with, and whether they intend to be their own boss.

Licensing

Many, but not all, states have licensing requirements for HVAC technicians. (In some cases, licensing is required at the local rather than state level.) Becoming licensed often requires passing an exam. Plus, some states require you to have completed the equivalent of an apprenticeship program or two to five years of on-the-job experience before you can apply for a license to legally work on your own. You can use CareerOneStop's license finder to research the requirements in your area.

Additionally, most states require you to get a special license if you're aiming to work as an HVAC contractor. This guide provides details on the requirements for each state.

Certification

Some certifications are required; others are voluntary. However, even voluntary certifications can help you advance in your career since most employers like to see official acknowledgment of your competencies.

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. The Section 608 certification exam is a written test and is administered by a variety of organizations that have been approved by the Environmental Protection Agency (EPA), including unions, building groups, trade schools, and contractor associations.

Section 608 certification is broken down into four types:

  • Type I for small appliances
  • Type II for very high-pressure appliances
  • Type III for low-pressure appliances
  • Universal for all types of HVAC/R equipment

Many formal HVAC programs prepare their students to take the EPA Section 608 Universal certification test.

Technicians who work on air conditioning systems in motor vehicles must complete Section 609 certification.

The EPA does not require any additional certifications for technicians who work with R-410A refrigerant. However, since this type of refrigerant is used at a much higher vapor pressure and therefore requires different tools, equipment, and safety standards, some trade schools and training providers offer classes related to R-410A specifically.

Other types of voluntary professional certifications are designed to verify the real-world skills and working knowledge of technicians who have 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 HVAC Excellence and North American Technician Excellence (NATE).

Education & Training FAQs

How can I prepare for an HVAC program?

Taking high school courses in subjects such as mechanical drawing, basic electronics, math, computer science, and applied physics and chemistry can be helpful. It can also be beneficial to gain some basic knowledge of electrical and plumbing work.

What's required in order to start an HVAC apprenticeship?

Generally speaking, HVAC apprentices must:

  • Be at least 18
  • Hold a high school diploma or equivalent credential
  • Be comfortable with algebra
  • Have a valid driver's license
  • Pass a drug screen

Keep in mind that apprenticeship openings are often highly competitive. Completing an HVAC program at a technical college or trade school can give you a leg up on the competition when applying for a registered apprenticeship.
