“The purpose of Modern Automotive HVAC: Electrical and Electronic Systems is to educate the reader about the importance of the electrical system in relation to the HVAC system,” explained Elvis L. Hoffpauir, MACS president and COO. “Often a technician will install refrigeration-related components, only to find that the compressor clutch will not engage or the cooling fans will not operate. Another scenario could be that the A/C system has a full refrigerant charge but the compressor clutch will not engage, or the A/C control panel will not change blower speeds or distribute air from the proper duct.

"This book will cover the fundamentals of electricity, required test equipment and test procedures. It will also address the electronics utilized in HVAC systems, including the inputs from the powertrain electronics that affect A/C operation," he continues. "With the increased use of electrical and electronic controls and sensors, it is important that all persons involved with vehicle repair have at least a working knowledge of electricity and electronics.”

Modern Automotive HVAC: Electrical and Electronic Systems, covers the following topics: Safety and precautions, electrical basics, the multi meter and circuit designs, wiring diagrams and service information, introduction to electronics and system controls, electrical/electronic troubleshooting and diagnosis, HVAC control systems, blower motors and cabin air filters, and air delivery systems.
