Home Performance Diagnostics: the Guide to Advanced Testing

Well written book. The testing procedures are explained and sequenced out with high quality photographs. The author is a tremendous teacher. You will not be dissapointed at all.To put it another way. I have been researching many of the tests performed in the book on YouTube for some time. I have found many professionals have posted videos of their work on YouTube. They include great testing techniques but only film on jobs and therefore do not generally have much time. Explanation about what or why they filmed what they did are seldom. This author has videos of countless tests/discussions/Webinars posted on YouTube that put the topic into your thoughts as well as reality. Nothing but encouragement from the start. How many experts around are 1) qualified to write a book 2) willing to take time to teach and wants to see the reader reach the full height of their potential. Terrific use of your time.

Arrived as described, on time, and no problems.
