HVAC/R I & II 

Hello, my name is Francisco Ysaguirre, and I am the HVAC teacher at Harlingen High School South. I want to welcome you to the exciting world of HVAC and Refrigeration! Here we learn a variety of skills to take with you into the work industry such as safety, basic electricity, as we work with high and low voltage circuits. Students are also taught the principles of a refrigeration system and all the components that come with it. From contactors to relays to capacitors, students will learn not only how to install these parts, but also how to diagnose problems within the system. I am also a firm believer in teaching our students basic life skills needed for real life. They will learn soft skills for communication and our goal is to develop leaders in the workplace. So, here's to another great year at HHSS HVAC program.
