Refrigerant Charging and Service Procedures for Air Conditioning 2nd Edition

The $100 well spent very informative literature. I enjoy reading this book very well detail about each part of HVAC system.

Book is great. It's very informative and has photos and steps to follow. It's very detailed. I've recommended this book to other Technicians.

Was in the automotive industry for 40 years plenty od AC work but never really having a true understanding of how it works . I have taken an interest in HVAC and have to say this book along with the online videos are some of the finest teaching materials on a subject that I have ever had the pleasure of using !!!

I expected nothing less. The printing is perfect, and the quality of the teaching and illustrative materials are excellent. I would love to see this type of book available in the field of residential and commercial electricity.

Achieves that clear and crisp "finally, I get it" explanation of key ac aspects of hvacr. Would highly recommend.

Awesome book and well worth the money. I can't thank the author enough for sharing his knowledge with this book and videos. I'm a homeowner with previous automotive A/C experience and EPA cert. I was able to figure out why one evaporator was freezing up on one of my two HVAC systems and got it fixed. Identified what type of metering device my system hasand what was going on with it. Learned that it was a piston type and how to check the charge by superheat. I evacuated the system, fixed the blocked orifice, pulled a vacuum, recharged the system and checked for leaks. Both my units are 2.5 ton R22 so I doubt anyone would even want to service them and just try to sell me a new system. With the help of this book, I saved thousands of dollars. System is now working great. After reading this book, I am confident that I could replace the entire system by myself.

I never thought I would spend this much on book, but I am halfway through it and it is one of the best and most instructive books on HVAC. I read the free sample and that was that and I parted with my money and glad I did. Thanks

Excellent book. If you want to know about HVAC - buy this book.
