Take Action
Older ducts are typically leaky and not insulated. Insulate ducts in unconditioned areas, including attics and crawlspaces, and keep them in good repair to prevent heating/cooling losses of up to 60% at the registers. A minimum of R6 insulation is suggested and new, high-performance duct systems may be required.

    No matter how efficient your heating and cooling equipment is, if your home is not properly sealed and insulated, you may not be as comfortable as you could be, and your heating and cooling systems will have to work harder. Additionally, if you have leaky or poorly insulated ductwork, your home might have humidity problems, excessive dust, or rooms that are never quite comfortable. Improving the building shell and sealing ducts can generally improve your home.
