Summary

Extensively illustrated, clearly written, and state-of-the-art in focus, this comprehensive MHVAC manual is ideal for both novice and advanced technicians. ASE-based in coverage, it focuses on the generic theory that underlies the operation, diagnosis, and repair of the MHVAC units and subassemblies found in the many makes and types of vehicles students will likely encounter on the job. Features 52 Real-World Fixes (case studies) showing how technicians have solved and repaired difficult problems, and 85 Service Tips (procedures that can bring a job to completion faster or ensure a more thorough repair). The volume has the support of much of the RVAC and Santech Industries cooling system repair industry. Basics of Heating and Air Conditioning. Heat Movement Theory. Refrigerants and the Environment. Moving Heat: Heating and Air Conditioning Principles. Air Conditioning Systems. Air Conditioning System Components. Heating Systems. Air Management Systems. HVAC System Inspection and Trouble Diagnosis Procedures. A/C System Inspection and Diagnosis. Heating and Air Management Systems Inspection and Diagnosis. HVAC System Electrical or Electronic Controls, Theory, Inspection, and Diagnosis. Refrigerant Service Operations. A/C System Repair. Cooling System Theory. Cooling System Inspection, Trouble Diagnosis, and Service. A reference for working automotive MVAC technicians.
