Electricity for HVACR was written to help aspiring technicians with no electrical experience or training to understand the operation of HVACR electrical circuits. The text avoids theoretical discussions of circuits in order to focus on its main goal–showing students how to diagnose and solve electrical problems in HVACR systems. Using the spiral-learning concept, each new unit of the text builds on content learned from the previous unit. From how to use diagnostic tools and instruments safely to understanding diagrams and even coverage of the green ECM motor, the text’s many examples, tips, and step-by-step instruction help students learn to apply troubleshooting skills to real electrical problems.
