Heating and cooling a home uses more energy and drains more energy dollars than any other system in the house, according to the Department of Energy (DOE). Typically, 44% of the 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% of the nation’s sulfur dioxide and 12% of the nitrogen oxides, the chief ingredients in acid rain.
