Seal your Air Ducts
Leaky ductwork often accounts for 10 to 30 percent of total heating and cooling costs.
Check for Air Leaks & Disconnected Sections
Look for holes or sections that are not joined together. If you use tape to seal your ducts, avoid cloth-backed, rubber adhesive duct tape, which tends to fail quickly. Researchers recommend other products to seal ducts: mastic, butyl tape, foil tape, or other heatapproved tapes. Look for tape with the Underwriters Laboratories logo.
