Improve your home's insulation
Without proper insultion, air leaks through your home's envelope − the outer walls, windows, doors, and other openings − wasting energy and increasing your utility costs. A well-sealed envelope, coupled with the right amount of insulation, can make a real difference on your utility bills, the EPA estimates that homeowners can save an average of 15% on heating and cooling costs.
Simple fixes include installing weather stripping on doors and caulking around windows, while bigger jobs might include sealing leaks and adding insulation in your attic.
