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 and also perform a Comprehensive Home Assessment that includes much more detailed testing. You can also do some of the steps yourself. Items shown in the video below include checking for leaks, examining insulation, inspecting the furnace and ductwork, performing a blower door test and using an infrared camera.
