A/C & Refrigeration Systems
Course Overview
The goal of this Air Conditioning and Refrigeration Systems course is to provide a broad introduction to air conditioning and refrigeration systems. It is designed to train and prepare students for entry as service and maintenance technicians. Students are taught common practices for general operation and maintenance of their RAC systems. The course is a great overview for RAC technicians, or anyone seeking to improve their RAC operation and maintenance skills. The students would learn skills that support the installation, testing, and servicing of a refrigeration system. This would help them keep the systems up and running as efficiently as possible.
