Professionally-Sealed Comfort Delivery System

Leaky ducts can dump conditioned air into attics and crawlspaces, or pull in air from these same types of spaces. Both outcomes wastes energy and reduce the amount of heated or cooled air that reaches its destination, and can cause other problems with odors and contaminants. Professionally sealed comfort delivery systems are well sealed at all seams and connections with approved sealing tape or mastic, a type of paint-on adhesive, before they are insulated. Thus sealing helps air get where it is needed, at the correct temperature, without contaminants from crawlspaces and attics.
