Overview

Homeowners will more likely attempt to change a washer in their kitchen's leaky faucet; install a light switch, or even add an addition to the bathroom before they ever consider attempting to address issues with their HVAC system due to its unique capabilities, functionality and design. In comparison, most informational books in the same category are much too technical, leaving the reader at a lost, and frustrated. HVAC Tips 101 "…Before you call your A/C & Heating Contractor" is not only user friendly, it also provides quick-easy-safe to use instructions. In addition, this book offers an honest approach to letting the reader know when they have reached the point beyond their scope of trouble shooting. The outline of this book is designed to help the reader trouble shoot while learning basic theory along the way of its role in the systems operational process, while keeping it comprehensible.
