How Long Does Air Duct Sealant Last? - A Comprehensive Guide

Duct putty is a popular choice for air duct sealing among many industry professionals. This sticky material is non-toxic, flame resistant, and does not harden over time. It can be applied with a caulking gun or spatula and can last up to 20 years. The Aeroseal system is designed to last up to 40 years and comes with a 10-year warranty when installed following its patented procedures.

Air duct seals are designed to last between 15 and 30 years, but this can be affected by lack of preventive maintenance. Having Triple Service Inc professionally maintain your air ducts every year will ensure that both they and your sealant last as long as they should. Your local home service or HVAC contractor can tell you if the ducts need to be cleaned before sealing them. Air duct sealing is a process that involves applying a specialized putty sealant or metal tape to all joints and connections in an air duct system. If you notice an increase in your energy bills without an increase in consumption, this could be a sign that there are leaks in the air ducts and you may need to seal them.

Aeroseal seals air leaks in air ducts to help improve the air supply capacity of heating, ventilation, and air conditioning (HVAC) equipment. The inspection detects any obvious breaks in the ducts and, as an initial step in the sealing process, the Aeroseal system will determine the exact amount of leaks in the duct system. Duct leaks can contribute to air loss in your home's air conditioning system and increase heating and cooling costs. When air ducts aren't well sealed, they can cause significant energy losses, increasing your utility bills over time. Air duct leaks not only waste energy, but they also cause many other airflow problems in homes and buildings.

Many people are surprised to learn that homes often lose 30 to 40% or more of their air through air duct leaks. But yes, ducts made of all kinds of materials can be successfully cleaned once sealed with Aeroseal.
