Air Leaks and Insulation
		Check your home for air leaks. Common sources of air leaks include cracks around doors and windows; gaps along baseboards; mail chutes and pet doors; cracks in brick, siding or foundation; and where external lines (phone, cable, etc.) enter your home.
		Plug air leaks with caulking or weather-stripping. This may help save up to 10% on your energy bill.
		Consider replacing old windows. Storm or dual-glazed windows can reduce heat gain by as much as 50%. New windows often pay for themselves within five years.
		Adequate insulation in your attic, ceilings, walls, floors and crawlspaces can save up to 30% on your energy bill. Read more about insulating your home: Save Money without Sacrificing Comfort.
