If you experience duct leakage, it's important to fix the problem as soon as possible. Here are some tips for repairing a duct system:

1. Check for obstructions in the ducts. Remove any objects that could be obstructing the flow of air or causing leaks. This includes dust bunnies, pet fur, leaves, and other debris.

2. Clean the ducts using a commercial cleaner or a degreaser and scrub brush. Use hot water to help loosen debris and corrosion. Rinse the ducts clean and dry them before proceeding to step 3.

3. Repair any damaged or leaking parts with an appropriate sealant or repair kit. Sealant is available in premixed kits or can be purchased separately at most hardware stores.

4. Check for proper ventilation of your attic space and make adjustments as necessary to allow air movement through your home's interior structure and out of the attic space.
