Heating, Ventilating, Air Conditioning and Refrigeration

We offer a seven quarter, two-year Associate’s Degree of Applied Science (A.A.S) in HVAC/R. Graduates of the program are prepared for entry-level positions as a technician in the HVAC/R trade, a rewarding career that is fast-paced, challenging, and requires an independent mindset.

Students of the SCC HVAC/R program study electrical theory, motors, controls, refrigeration theory, gas and electric furnace troubleshooting, air conditioner and refrigeration system troubleshooting, heat pump troubleshooting, and computer based digital controls. Please see course descriptions for a detailed listing of each course and learning topics.

Hands-on learning and troubleshooting is an important part of our program. The SCC HVAC/R lab has over 120 pieces of operational equipment for students to learn on and practice with. All pieces of equipment were installed by students, and have been maintained by students. Classroom theory is backed up with real-world testing, measurement, and troubleshooting on actual pieces of equipment students will see in the field after they graduate. An optional internship is available sixth and seventh quarters as well. Students will have the opportunity to take the tests to receive their Spokane Gas Heating Mechanic’s 1 License and EPA 608 Universal Refrigerant Handling License. Students will also register to receive their WA L&I Electrical Trainee License, and will start to receive credit for hours that will apply towards an electrical license.
