Duct Repair & Sealing in Louisiana

In a typical house, 20–30% of the air moving through the ducts leaks out. In a 140°F Las Vegas attic, that leak means paying to cool the attic. A duct leakage test finds out how bad it is, then techs repair the disconnects and seal the joints with mastic or an aerosol sealant.
