Take the lead in heating and cooling

Learn all the skills and prep for more

“Turn the heat up”—it’s an everyday, common task. Most people only think about what the temperature change means for their monthly bill.

You know better: it’s a shift in how the heating, ventilation, air conditioning and refrigeration (HVAC/R) plant for the home or business operates. Electrical wiring, thermodynamics and mechanical processes all work together to heat and cool our spaces.

Earning an Associate in Applied Science (A.A.S.) means you learn it all: how to install, test, troubleshoot, maintain and repair furnaces, air conditioners, and the reach-in or walk-in refrigerators used by supermarkets, restaurants and stores. You also take college classes to round out your general education—classes in math, science, history and English. You’ll use those classes throughout your career as you talk with customers and coworkers and as you take on more responsibility as a supervisor or service lead.

What can you do with an A.A.S. in HVAC/R Engineering Technology?

The Associate in Applied Science (A.A.S.) degree in HVAC/R Engineering Technology prepares you to go to work in HVAC/R and to advance into a role as a supervisor, service lead or small business owner.
