The HVAC/R Professional's Field Guide to Universal R-410a Safety & Training: Delta-T Solutions Kindle Edition

I love this book. Great explanations and visual graphs,pictures, and charts are easy to follow and understand.

I don't know that I'm going to actually test to get certified but even if I don't this book is well worth the money for a newcomer like me.

This manual was just what I wanted. I had been out of the field for a few years and wanted to know all I could learn about R410A and about it's characteristics and origins. (I am installing a new GoodMan 16 SEER airconditioner in my older home and replacing the old.... no more R22, right?) :-) This is about as clear, basic, and cogent information as one can get. It is low cost, and well presented. I feel as if I have had a quick full day , 8 hour, "update" course on R410A and related aesiotropic refrigerants. I heartily recommend this book to anyone who just wants to know more, get some technical and legal details, and yet not wade through a huge technical manual. There things about R410A that - anyone who is planning to work with anything that is R410A filled - needs to know. NOTE: You do need to know what this book presents so simply. This is NOT the old R22 system we all grew up with. Enjoy!

I like precise terms of every HVAC/R wordings and terminology. This book would be more helpful if pictures and diagrams and illustrations are take account with terminology. I am reading this book to be best out it. Thanks

big book. I enjoying it

Helpful information!!!

After replacing my r22 central air conditioner with a new system which uses r410a, I made this purchase in the event I need to service my air conditioner. I am very satisfied with the price and delivery and highly recommend this product.

As a guy who just passed his Journeyman Test, this book was an invaluable study guide to prepare for my 410-A certification.
