What Is Duct Sealing?


Get the scoop on professional duct sealing and find out how it can improve your HVAC energy efficiency.

What is duct sealing? No, we aren’t talking about the type of duct sealing that involves duct tape! Professional duct sealing involves using professional grade materials—typically a special adhesive called mastic—to create a seal that lasts long-term. Sealing the holes and tiny cracks in your ductwork will ensure you aren’t paying hard-earned money to send your cooled air into the great outdoors this spring and summer.

When you choose to get professional duct sealing, you can be sure your ductwork will be tight and secure, so all the cool air goes into your home where you need it most.

What to Expect from Traditional Duct Sealing

Whether duct sealing takes place during a routine preventative maintenance visit or you call for this specific service, the process typically goes something like this:

  • A trained technician assesses your ductwork for cracks and holes and identifies the areas that need sealing.
  • The tech brushes on the mastic where necessary and places a fiberglass tape or special foil to provide reinforcement for the seal.
  • Once dry, the holes and cracks will have a secure seal to keep cooled air in and debris out of your ductwork.

Wilson's Refrigeration and A/C Service has been providing me with excellent maintenance on my home HVAC for over 10 years, extending the life of my unit considerably. Their techs are knowledgeable, responsive, skilled, and pleasant to deal with. They are available 24/7 and prompt when an occasional emergency occurs, especially after hours. Most recently, after thorough consultation with Jimmy, we elected to replace our aging unit with a carefully selected top of the line hybrid HVAC (electric and gas). I couldn't be more pleased with our new unit and their continued maintenance. They are good people to deal with.
