Duct Sealing

Your air ducts carry air conditioned or heated air to the different rooms in your house. When not installed or maintained correctly, about 20 to 30 percent of conditioned air is lost because of leaks, holes, and poorly connected ducts. Duct sealing helps your cooled air reach your warmest room.

• A duct leakage tester is used to measure airtightness in ducts. Finding airtightness in your ducts is valuable information when you are trying to conserve energy because it shows where leaks and holes are located in your ducts.

• Sealing your ducts to less than 10 percent air leakage will help improve comfort around your home.
