ABSTRACT:
A cover assembly for ceiling registers connected to the air ducts or the trunk line of a central air conditioning system. The cover assembly is designed to prevent heat and moisture from entering the trunk line through the register or any wall sleeves, gaps and openings. The cover assembly is comprised of a flat rigid material of sufficient size to cover the opening of a ceiling register. The cover has a peripheral seal that presses against the rim face of the register by a fastening device. The fastening device attaches to the ceiling register to secure the cover to the ceiling register with an air tight seal.
