  • A window's ability to insulate is given by its U-value. The lower the U-value, the more efficient the window.
  • Look for the National Fenestration Rating Council (NFRC) label as your guide to window energy performance.
  • Consider ENERGY STAR® qualified windows, they can help save up to 15 percent on your cooling costs.
  • Look for windows with energy-saving features such as: Low-E coating, double panes, and vinyl or fiberglass frames.

ENERGY STAR® estimates you can save up to 20 percent on heating and cooling costs just by insulating and sealing your home against air leaks alone. In homes with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical house, about 20 to 30 percent of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts.
 
  • Seal and insulate your attic. Air sealing in the attic can be a challenging do-it-yourself project, but the benefits can be substantial. If you’re not comfortable taking on this project yourself, there are many qualified licensed contractors who can help you get the work done.
  • Seal your heating and cooling ducts. Because ducts are often concealed in walls, ceilings, and attics, repairing them can be difficult, but there are things that you can do to improve duct performance in your house. Start by sealing air leaks using mastic sealant or metal tape, and insulating all the ducts that you can access. Never use duct tape, as it is not long-lasting.
