Duct Installation Tips & Tricks — We recommend that you seal the seams with a duct sealant after installation to prevent any air leakage, increase the efficiency of your system and reduce your utility bills. See installation tip for Flexible Duct or Sheet Metal Duct, depending on which type you will be attaching to.
