This is a practical book, written by a man who presently works in the field and has instructed in the field as well as in the classroom. This book is a reference manual that can be carried in your tool box. Much of the information was gained through work experience and does not appear in any other text or reference manual.
Students bring many different books on class field problems with them. These texts and reference books usually contain many pages with a lot of words that can not be related to the field. These books are merely theory presented in classroom lectures. Students want a “hands-on” reference guide that can easily be carried. This book fills that need.
Handy homeowners will find this book a helpful guide to making simple repairs and understanding how air conditioning works. Performing simple preventive maintenance procedures can save you—the homeowner—money, as well as spare you many unnecessary breakdowns.
