Updated to reflect the latest trends, technology, and relevant ASE Education Foundation standards, this integrated, two-book set covers theory and hands-on content in separate Classroom and Shop Manuals. This innovative approach allows students to learn fundamental climate control theory, including basic physics related to heat transfer, before applying their knowledge through practical, hands-on shop work. Cross-references in each manual link related material, making it easy to connect classroom learning to lab and shop activity.

In addition to a new chapter on electrical fundaments, the Sixth Edition includes extensive coverage on the newest refrigerant R-1234yf (HFO-1234yf).
This up-to-date, technically accurate guide is a valuable resource for students and professionals seeking ASE certification, or anyone interested in the principles, components, diagnosis, and repair of modern automotive heating and air conditioning systems.

This up-to-date, technically accurate guide is a valuable resource for students and professionals seeking ASE certification, or anyone interested in the principles, components, diagnosis, and repair of modern automotive heating and air conditioning systems. Enhanced coverage of core course concepts—ideal for those with a limited electrical training background—includes an-all new chapter on basic electrical theory, as well as a comprehensive introduction to HVAC climate control systems and sensors theory and diagnosis. Thorough coverage of the newest refrigerant to enter the market (R-1234yf) emphasizes both differences and similarities to existing systems and covers R-1234yf service and diagnosis, as well as specialized equipment requirements. New and revised job sheets reflect the latest ASE Education Foundation tasks, helping students develop the skills they will need to obtain certification and succeed as professionals in the automotive services industry. Separate Classroom and Shop Manuals allow students to focus on learning essential theory in the classroom and practical applications in the lab or shop, while cross-references in each manual make it easy to connect theoretical material to hands-on activities. Chapter-opening learning objectives related to current ASE Education Foundation standards help students understand certification requirements and focus their reading and studying appropriately. A highly detailed and technically accurate introduction to today’s principles and practices prepares students for success in diagnosing and servicing modern heating and cooling systems. A complete instructor support package includes useful teaching resources such as Microsoft® PowerPoint® presentations, chapter test banks, an image gallery, an instructor’s guide to the text, and a ASE Education Foundation correlation grid, all designed to save you time in the classroom.
