What is HVAC?

HVAC stands for heating, ventilation, and air conditioning. It is occasionally referred to HVACR with refrigeration added as a related specialization. The installers and mechanics who work in the field are called heating, air conditioning, and refrigeration technicians, or HVAC techs for short. Specially trained HVAC techs install, fix, and maintain the heating, ventilation, cooling and air conditioning equipment in buildings throughout Southern California. As masters of environmental control, if it’s hot or cold outside, but nice inside, you have an HVAC tech to thank.


Climate control provides comfort on an extremely hot or cold day. However, with some HVAC customers, a climate-controlled environment is critical to their organization. Refrigeration systems that keep food, medicine, and other perishable goods cold are critical to medical facilities, scientific labs, and food-service businesses.

HVAC techs work in office buildings, hospitals, stores, restaurants, factories and many other types of buildings that are in need of temperature, humidity, and air quality control. As an installers or technician working for an HVAC company, in a single work day you may go from a walk-in freezer to a blazing hot rooftop to fix or install equipment in these varying environments.

HVAC Training Programs

According to the US Bureau of Labor Statistics, due to the complexity of modern HVAC systems, “employers generally prefer applicants with postsecondary education or those who have completed an apprenticeship.”

Fast Track Stop Watch

The SBBCollege HVAC training program meets this growing demand by providing expert training and preparing grads to be ready to work in the HVAC field in about nine months.


Career Outlook

The US Bureau of Labor Statistics says that “employment of heating, air conditioning, and refrigeration mechanics and installers is projected to grow 14 percent from 2014 to 2024, much faster than the average for all occupations.” Those familiar with computers and/or electronics will have the easiest time finding career opportunities as new HVAC systems continue to grow in complexity.


HVAC techs do the following:
  • Install or repair HVAC equipment according to blueprints or technical specifications
  • Maintain and install plumbing lines and air ducts
  • Test and install electrical wiring and control systems
  • Inspect, install, maintain, and repair HVACR systems
  • Monitor energy use and recommend improvements


HVAC techs use a variety of basic hand tools common to electricians, plumbers, and mechanics, as well as (according to the Bureau of Labor Statistics) sophisticated HVAC tools, including “carbon monoxide testers, voltmeters, combustion analyzers, and acetylene torches, to test or install system components.”

Specialized work

Most HVAC techs are trained to conduct a variety of duties from installation to maintenance, diagnostics, and repair of heating, air conditioning, and refrigeration equipment. However, some specialize in one or more areas, including solar, radiant heat systems, boilers, or commercial refrigeration.
