Associate in Occupational Technology Degree
Air Conditioning and Refrigeration
The Air Conditioning and Refrigeration program is designed to prepare individuals for employment as heating, ventilation, air conditioning, refrigeration technicians (HVACR). The program places an extreme emphasis on safety, thermodynamic principles, basic electrical and refrigeration theory and their applications to specific types of HVACR equipment. Students receive training in troubleshooting and service techniques needed to install, service, and repair many types of equipment. Specific equipment training includes, but is not limited to, residential and light commercial air conditioning, heat pumps, gas heating, electric heating, commercial ice makers, and commercial refrigeration. Students will also receive training in laws governing proper refrigerant handling procedures per the Environmental Protection Agency (EPA) Regulations. Students completing the air conditioning and refrigeration program will be required to participate in credentialing activities such as EPA Section 608 Refrigerant Handling, R-410a Refrigerant Safety Certification, Industry Competency Exam (ICE), and NOCTI
