Energy 101: Home Energy Checkup (Video)
A home energy checkup helps owners determine where their house is losing energy and money—and how such problems can be corrected to make the home more energy efficient. A professional technician—often called an energy auditor—can give your home a checkup. You can also do some of the steps yourself. Items shown here include checking for leaks, examining insulation, inspecting the furnace and ductwork, performing a blower door test, and using an infrared camera.
