There's no question that it pays to be an informed consumer. Knowledge of your home's systems helps you control repair and construction costs and make sure the correct elements are being installed or replaced.

This book uncovers the mysteries behind just about every major appliance and building element in your house. Clear, "exploded" drawings show you exactly how these things should be put together and how they function - what to check if they don't work, and what you can do that might save you having to call in a professional.

The easy-to-understand pictures and explanations on every page get right to the point, helping you understand how things work, what can go wrong, and how to trouble-shoot a problem.

Virtually everything in your house is included:

• Electrical - circuit breakers and grounding, service, outlets, lamps and fixtures.
  
• Heating and Air conditioning - gas, electrical and oil - ductwork and piping, thermostats, central and window AC units, humidifiers and dehumidifiers, and air filtering systems.

• Major household appliances - from kitchen to laundry.
