How Does Air Duct Sealing Work?

Air duct sealing is a process where professionals use special tools and materials to repair and close any leaks or gaps in your air ducts. This process is critical because without proper sealing, your ducts will allow air to escape, lowering your HVAC system's efficiency.

The first step in air duct sealing is to test your ducts for leaks and other problems. Professionals use specialized tools like blower doors and duct blasters to identify any leaks or gaps in your ductwork. These tools pressurize your ducts and measure the amount of airflow, making it easier to identify leaks and gaps.

Once they have identified the leaks, professionals will seal them using mastic, foil tape, or other specialized sealing materials. Mastic is a putty-like substance that is usually spread over the leak or gap and then left to dry and harden. Foil tape, on the other hand, is a strong adhesive tape that professionals use to seal gaps in the ductwork.

Air duct sealing can also involve replacing damaged ductwork. If your ducts are old, cracked, or damaged, professionals may need to replace them entirely to ensure your HVAC system runs efficiently. They may also repair bends or kinks in the ducts, eliminating any airflow restrictions that may be causing noise in your ducts.

Proper air duct sealing not only reduces noise in your ducts but also helps improve the overall energy efficiency of your HVAC system. By reducing air leaks and gaps in your ductwork, you can save energy and money while enjoying improved comfort in your home.
