HVAC-R Certification (Diploma)

    Program Description

      About the program

    The Heating, Ventilation, Air Conditioning and Refrigeration (HVAC/R) program at ASA is lab-based with almost every class meeting having a hands-on (learn-by-doing) approach where students train and work on actual air conditioning and refrigeration equipment.  This lab allows students to gain experience in equipment installation, maintaining air conditioning units, troubleshooting equipment failures and refrigeration systems.


    Commercial and residential

    The HVAC/R program covers both commercial and residential technician skills in order to expand the marketability of graduates with real-world career opportunities.

    What do HVAC/R Technicians do?

    Heating, Ventilation, Air Conditioning, and Refrigeration (HVAC/R) technicians provide valuable services so people can live in comfortable climate conditions indoor.  In addition, many restaurants and food service industry businesses need refrigeration services.  HVAC/R technicians typically do the following:

    • Install, maintain, and repair heating, cooling, and refrigeration systems
    • Repair or replace defective air conditioning and refrigeration equipment
    • Repair and replace equipment’s components and wiring
    • Use blueprints or design specifications to install or repair HVAC/R systems
    • Connect systems to fuel and water supply lines, air ducts, and other components
    • Install electrical wiring and controls and test for their proper operation
    • Inspect and maintain customers’ HVAC/R systems
    • Test individual components to determine necessary repairs
    • Repair or replace worn or defective parts
    • Determine HVAC/R systems’ energy use and make recommendations to improve their efficiency

    Employment outlook

    According to the Bureau of Labor Statistics, employment of heating, air conditioning, and refrigeration mechanics and installers is projected to grow 14% from 2014 to 2024, much faster than the average for all occupations. Candidates familiar with computers and electronics and those with good troubleshooting skills will have the best job opportunities as employers continue to have difficulty finding qualified technicians to install, maintain, and repair complex new systems.
