The duct seal has a minimum lifespan of 10 years, and many homeowners don't realize that an air duct system will degrade over time. After all, very hot air is passing through those ducts, and rodents and other creatures can enter them and cause damage, as well as humidity or other environmental factors leading to fraying of air ducts. Inspecting and sealing your air duct system is one of the most effective ways to reduce air conditioning and heating costs, as well as helping you stay cooler in summer. In addition, as Aeroseal's certified air duct technicians, DuctMedic is qualified to execute a program created by the Environmental Protection Agency (EPA) called “Duct Investor”.
This program takes into account a wide range of variables and provides a homeowner with the best available estimate of what they should expect in terms of cost savings.

Yes, tell your customers that they have to remove all the drywall from their house to hand seal the rest of the ductwork. Therefore, the warranty, the strongest warranty in the industry, covers the contractor for 10 years for parts and labor in the event of any failure in the Aeroseal seal, but the Aeroseal seal itself has proven to last for decades. In many cases, the air duct system can reduce the heating or cooling capacity of a system to less than 50 percent of its efficiency. This is the second part of the questions that both homeowners and contractors ask us about sealing Aeroseal ducts in homes.
