This book has everything needed to do a manual J. I have no AC experience, especially for calculating size of system and air flow into each room, but by reading through this book and working with a spreadsheet, I was able to adequately perform a Manual J analysis sufficient to determine that my AC system is working properly, is sized properly, and the air flow in most of the rooms in the house is sufficient.
The calculations using a spreadsheet allowed me to vary factors such as max design temperatures to show me why my system was not cooling as I thought is should in 98 F temperatures. I was also able to play with different levels of insulation in the attic to see what the best R value is for the money. It is easy to see the diminshing return on investment as the R value gets sufficiently high.
What I did not care for in this book is the way it is organized. There are a number of things that are repeated over and over, chapter to chapter that are relatively easy to grasp, and then some very important items are mentioned once or twice and somewhat hidden. Also, nomenclature is not deffined very well and used in some cases without prior definition as far as I can remember. The book could be reduced many pages and be easier to follow if a lot of the simple redundancy is removed, and important items are presented more often and clearly.

There are a lot of tables and charts that are not displayed clearly and you can't zoom in to get a better view.
It's the type of book that you need to reference other pages while reading and the kindle format does not make that easy.
