Most heating, ventilation, and air conditioning (HVAC) employers seek out candidates with some formal HVAC education or apprenticeship training, according to the Bureau of Labor Statistics. The majority of HVAC programs offer diplomas or associate degrees, though bachelor degree programs are also available.

Many HVAC technicians receive their training through an apprenticeship. Many programs are offered through chapters of organizations such as the Mechanical Contractors Association of America, the Air Conditioning Contractors of America, and the Plumbing-Heating-Cooling Contractors—National Association.

HVAC students should be sure to seek out programs that lead to the necessary certifications required to practice in the field. Those who work on refrigerators, for example, must be certified by the Environmental Protection Agency (EPA). Certifications are available in small appliances, high-pressure refrigerants, and low-pressure refrigerants.
