What is Duct Sealing?
Homes that have forced-air heating and cooling systems use ducts to move air from the heating or cooling source throughout the home. Duct sealing in your home can allow for proper airflow creating a comfortable living space. Even in new construction, approximately 20% – 40% of the air flowing though the ductwork is lost through poorly sealed areas, holes, and leaks. In older homes the duct loss can be much more. PTCS Certified Technicians use a product called mastic to ensure longevity and quality assurance when sealing ducts. Mastic is a flexible sealant that never fully hardens and expands and contracts concurrently with ductwork.
