This book was used in my "Fundamentals of Electricity" course in a technical college air-conditioning (AC) program. It was selected because it was the only text specifically for AC. We used the first third of the book. I'm an older student, have two years of university credits, and have seen a lot of technical and vocational training material. This book is simply awful. I have never had to struggle with a textbook so hard as with this one. Grammatical errors were abundant. The review questions were poorly written. Illustrations were occasionally mis-labeled, out of sequence or just plain wrong. Where the material raised a question, it was often left unanswered, but unasked questions were answered in excruciating detail. I had to use 4 other books to fill gaps left by this one. Most insulting was the price: $108. There are better books that cover basic electricity, some aimed at HVAC. I used Proctor & Mazur's books from ATP to fill some gaps. Additionally, ARI's "Refrigeration and Air Conditioning" has a good treatment, which is clearly written.

Ideal for students and beginning technicians, Electricity for Refrigeration, Heating and Air Conditioning, 7E zeroes in on the basic electrical principles necessary to understand today's modern control systems. This extraordinarily practical approach allows readers to focus exclusively on the electronics information they will use in the field, without bogging them down in unnecessary theory. Chapter 9 includes new information on motor frames and electronically commutated motors, ECM.Such as the circuits being discussed in schematic diagrams, as well as the direction of the current flow within circuits. As in past editions, emphasis is on developing systematic diagnosis and troubleshooting methods and procedures in order to enable readers to become highly-skilled, professional HVAC-R service technicians. A comprehensive glossary is also included to assist those who are new to the field in understanding and using industry terms.
