Students test and service an air conditioning unit, perform electrical, mechanical, and maintenance
tasks. They also learn about the installation, maintenance, and operation of residential air conditioning and refrigeration systems. Principals of air conditioning and refrigeration are explained,
including gas expansion and compression, heat transfer, evaporation, condensation, thermostatic
control, motors and electrical circuitry. Students calculate cooling requirements and perform hands-on electrical, mechanical, and maintenance tasks in a realistic job simulation.

Curriculum manual is provided in a three-ring
binder, with pages contained in page protectors.
Easy to follow step by step activities are highlighted
using full color photographs. Once introduced to
career related information (job description,
education and training requirements, job prospects, and income ranges) the student begins a "hands on" work experience, using professional tools of the trade to complete projects or tasks. An audio tape follows the manual word for word. Pre-and post tests, worksheets, answer sheets, and instructors guide.
