Heating and cooling your home uses more energy and drains more energy dollars than any other system in your home. Typically, 44 percent of your utility bill goes for heating and cooling. What's more, heating and cooling systems in the United States together emit over a half billion tons of carbon dioxide into the atmosphere each year, adding to global warming. They also generate about 24 percent of the nation's sulfur dioxide and 12 percent of the nitrogen oxides, the chief ingredients in acid rain.
