Before It Breaks is your personal one-on-one with a heating, ventilation, and air conditioning (HVAC) service technician. This book won't teach you to be a tech, but it will give you the knowledge, tools, and empowerment to address issues and save money-before it breaks. We'll cover how the equipment in your home works, and what to do when it doesn't. You'll also learn how to choose an HVAC company and build a good relationship with your technician. All of this is delivered in plain, easy-to-understand language. Also-pictures!
