Heating and air conditioning are the largest energy expense in most homes, making up about 48% of overall energy use. During the winter, cold outside air often seeps in through the bottom of the home while indoor heat rises and escapes. This wastes valuable energy and drives up heating costs.
To conserve energy and lower your energy bills, insulate and air seal your home. This will keep valuable heat from escaping in the winter and unwanted heat from seeping in during the summer.
