Most new homes have some kind of duct work or HVAC unit in the attic. What they are likely missing is proper insulation to maximize energy efficiency. If you have an unfinished attic, having it properly insulated could save you 10 to 50 percent on your heating bill. Efficiency is also improved in warmer months; a well-insulated attic will keep your home’s temperature stable, making it easier and less expensive to cool.
