Courses You'll Take at HVAC School

There are a couple of options when it comes to getting your HVAC technician degree or diploma. You can join a hybrid program, which is both online and through your local school, or you can choose to go the traditional route of attending classes on a school campus. You’ll find that most programs consist of fairly similar courses so pick the program best suited to your needs.

Common HVAC Courses:

  • Principles of refrigeration: Learn the basics and applications of refrigeration systems.
  • Residential gas heating: Learn about gas-fired appliances, along with troubleshooting and repairs of the systems.
  • HVAC building systems: Learn how to design and construct comfort control/climate control systems for commercial buildings.
  • Heating and cooling systems: Learn how to apply sizing calculations to climate control.

How Long Is HVAC School?


  • Apprenticeships last 2-5 years.
  • Trade schools last between 6-18 months.
  • Community college takes 2 years if you attend full time.

About Apprenticeships

After you receive your high school diploma or GED, you can apply for an apprenticeship program. An apprenticeship program is a paid training position that lasts between 2-5 years. It’s a great way to start earning money while learning a trade. You must have 2,000 experience/work hours plus 144 hours of coursework per apprenticeship year.

The best bet for scoring an apprenticeship is to apply through your local chapter of a trade organization. Through these apprenticeship programs, you’ll be learning how to read and use blueprints, understand safety practices, proper use and care of tools, and ventilation and air conditioning system designs.

While doing an apprenticeship is certainly a great option, some employers are leaning more toward hiring HVAC technicians that have been trained through a trade school or community college.

HVAC Licensing Requirements

Licensing is required to work as an HVAC technician. It proves to employers and customers that you’ve been properly prepared for the job. In order to become licensed, you must complete some sort of training, whether it’s through an apprenticeship, a trade school, or a community college. Once your formal education is finished, you will be eligible to take the knowledge-based licensing exam.

The test content and length varies by state, as well as the testing location. The HVAC exam will test you on every aspect of HVAC installation and repairs. If you’re going to be working with refrigerants, you’ll be required to take the Section 608 Technician Certification exam, as well. The exam is given through the International Code Council. Each state has its own location where the exam is given.

There are a few eligibility requirements that need to be met in order to get your HVAC technician license:

  • You must be a minimum of 18 years of age.
  • You must be fluent in English.
  • You must complete an HVAC training program.

HVAC Certifications and Why You Should Become Certified

Certification and licensing and two different things. The license proves you’ve successfully completed your training and have the basic knowledge and skills to effectively do your job as an HVAC technician.

Certifications, on the other hand, are a step above the licensing aspect. With certifications, you'll prove you have broadened your HVAC horizons. Specializations are available in a few different areas.

EPA 608 Certification: The Environmental Protection Agency (EPA ) requires anyone handling refrigerants to be certified. All HVAC technicians must have, at the very minimum, the EPA 608 Certification so that they can legally do the bare-bone essentials of their trade, as well as the nationally recognized NATE Certification, and the Excellence Certification.

Within the EPA 608 Certification, there are four levels:

  • Type 1 allows an HVAC tech to handle small appliances that contain less than 5 pounds of refrigerants (i.e., a refrigerator).
  • Type 2 will allow the HVAC professional to deal with high-pressure refrigerants.
  • Type 3 allows the handling of low-pressure refrigerants.
  • The fourth type is ‘Universal’, which includes Types 1, 2, and 3.

North American Technician Excellence (NATE) Certification: This is one of the highest achievements for HVAC professionals. The NATE Certification is not required; however, it’s nationally recognized and highly respected which makes it a really good one to get. You become NATE certified by taking and passing the exam. You can earn a certification in areas such as air-conditioning, air distribution, and managing gas furnaces.

HVAC Excellence Certification: To be eligible to earn the Professional-level HVAC Excellence Certification, you must have a minimum of two years of on-the-job experience and pass the knowledge-based exam. You can also receive a Master-level HVAC Excellence Certification. You must meet the requirement of a minimum of three working years before you can take a portion of the knowledge-based exam.

The more certifications you have under your belt, the more desirable of an employee you’ll become! Certifications give you even more work credibility because they reinforce to employers and clients that, not only do you know your stuff, but you know it exceptionally well. Having certifications give employers and consumers a sense of security that the work is in very capable hands.

HVAC careers are plentiful, and if you’re willing to put in the time and become licensed and certified as an HVAC technician, you should have no problem finding your dream position. Our country is short-handed in skilled HVAC technicians.

License and Certification Fees

Licensing fee - Licensing can cost anywhere between $75-$300 depending on where you live.

Certification fee - Certification fees can range from $155 to over $200 depending on which certification you're pursuing.

Some states will require you to complete an apprenticeship or have 2-5 years of work experience before you can become licensed. You’ll need to check with your state to find out the exact requirements.

The reason for the price differences for the education, licensing, and certification costs is due to varying requirements and regulations for each state. Financial aid may be available, and options should be discussed with the financial aid department of the institution you’ll be attending.
