Just completed a Ducting job at a customers home. The customer previously had original fiberglass only ducting, which allows leaks and has extremely poor airflow. We redesigned his ducting layout as well as changed to a newer more efficient type of ductwork called Flex Ducting. Flex ducting has 3 layers compiled together to make for a efficient, cost effective, zero air leakage option for those who have either asbestos, fiberglass, or old ducting that are looking to replace.
