The Difference Between HVAC Certification and HVAC License

By Lorn H.

Heating, ventilation and air conditioning (HVAC) technicians are skilled tradespersons that install heating and cooling systems. Additionally, they maintain and repair the system when problems arise. This may be in a residential setting or for commercial facilities. Those who work for a retailer are often responsible for selling service contracts to clients.

Types of Certification


HVAC Certification

Becoming HVAC certified will depend on the type of certification that you desire and the training that you have achieved. Since many people work in the field under a licensed HVAC person, they may have some experience before taking classes. Those who have over a year of experience in installation and at least 2 years in maintenance will have a wider choice when it comes to the type of HVAC certification they choose.

This is required for admittance to most accredited HVAC training programs. These programs offer classes in the installation and repair of HVAC as well as reading blueprints, temperature control, construction and equipment design. The programs are available at various schools and colleges as well as online.

The programs are generally from six months to two years and depending on the length of the course, upon successful completion, the student will receive a certificate or an associate’s degree. There are also opportunities available for those who join the Armed Forces to receive specialized training in the HVAC field.


After completing the training program successfully, earning a certification or a degree, sitting for the HVAC licensing exam will be required by most states to work in this field. The licensing exam will differ somewhat from one location to another. The main consideration is the knowledge of all the aspects of installation and repair of HVAC systems. In addition, some licensing exams require the applicant to know electrical codes.

This includes high and low-pressure refrigerants and servicing small appliances. When this career is chosen at an early age, usually while in high school, it is beneficial to take classes that can help in preparing the student for the classes they will take next. The basic recommendations are mathematics, physics, electronics and mechanical drawing.

The qualifications to apply for a license as an HVAC contractor include being at least 18 years of age, speaking and reading the English language and four years of verifiable experience in warm heating. If the applicant meets these qualifications, they must take an ICC examination. The International Code Council (ICC) develops these exams and they are in charge of giving them for many states. As seen, the HVAC career is quite diverse. It can include various aspects of this profession, each having their own requirements and licenses.

What’s HVAC And How Does It Impact The Environment

 By Jon D Aguilar




“Green” is the latest buzzword in the HVAC industry. These systems were designed to heat, cool and ventilate air, but this added comfort came with a cost. When chemicals used were found to be harmful to us and the environment, steps were taken to phase them out and use more eco-friendly materials.

What’s HVAC ?

Do you know what’s HVAC ? HVAC is an acronym for Heating, Ventilation, and Air Conditioning. Ventilation may control the flow of air for both heating and air conditioning. However, ventilation also includes many more tasks.


Aside from distributing air that has been heated or cooled, ventilation can encompass all processes for exchanging air inside a given space. It may be necessary to ventilate in order to :

  • Refresh Oxygen Supply.
  • Remove Carbon Dioxide.
  • Eliminate Bacteria.
  • Reduce Moisture.
  • Prevent Odors.
  • Clear Dust.
  • Circulate Natural Heat.

That means it happens in one place and is distributed throughout the vents. Modern skyscrapers work by letting hotter air escape through the top of the building while simultaneously drawing in cooler and fresher air from the bottom. This type of natural ventilation is seen as reducing the burden on the environment.

HVAC Systems And The Environment

Speaking of the environmental impact, you may have heard a buzzword associated with HVAC called CFCs (chlorofluorocarbons). There is actually a long history about this issue because of the impact on the ozone layer and ultraviolet rays. Before CFCs, the chemicals used for cooling were often flammable or harmful to breathe. In 1928, Thomas Midgley, Jr. introduced CFCs. This was an improvement at the time.

The agreement to phase out CFCs began as the Montreal Protocol. As of today, all the members of the United Nations have signed it. In total, there have been 196 countries participating. What does all of this mean for you? When you hire an HVAC company to install, repair or upgrade your home’s system, you can choose “green” options. Most companies are now offering lots of ways consumers can help protect their health and the environment. There are also things you can do to keep your system in good shape so that it works more effectively, which saves you money and helps to save the environment.
