Ducts That Don't Leak
Your home's ducts move heated and cooled air to the living areas to make you feel comfortable. But in a typical house, 20 percent of the air that moves through the duct system is lost due to leaks, holes, and poor connections. The illustration below shows many common duct problems, such as:
- Leaky duct connections
- Leaky return ducts
- Furniture blocking registers
- Leaks at furnace and air filter slot and duct tape failures
- Fallen duct insulation
- Leaky supply ducts
- Kinks in ductwork restricting airflow
Photos of Poorly Sealed Ducts: Air leaking from ducts reduces heating and cooling efficiency by up to 20 percent. Leaky ducts also let dust, moisture, pollen, pests, and noise into your home.
Behind the walls of an ENERGY STAR certified home...
Tightly-sealed and well-insulated ducts keep you more comfortable and increase the energy efficiency of your home. Sealing also helps improve indoor air quality by reducing the risk of dust, moisture, pollen, pests, and noise from entering the ducts and circulating throughout your home.
Below are seven photos and two illustrations of tightly sealed ducts.

With new and more rigorous EPA guidelines to earn the label, ENERGY STAR certified homes are quieter and more comfortable than ever, have lower utility bills, and help protect the environment by reducing greenhouse gas emissions. Look for a home with the ENERGY STAR, the government-backed symbol for superior energy efficiency.
