Duct Sealing

The patented Aeroseal sealing process is an effective, affordable, and viable method of sealing ductwork in residential spaces. Aeroseal technology seals residential home's ductwork from the inside by using a UL tested and approved sealing material - an application which typically takes 4-8 hours. It's clean, safe, and guaranteed for 10 years in residential settings.

Aeroseal Resolves:
  • Air lost due to leaks
  • Temperature variations
  • Air flow issues
  • Backdraft and combustion concerns

During an air duct diagnostic, a certified Aeroseal technician will inspect your central air duct system and recommend ways to maximize your savings and improve comfort using the Aeroseal system. Major factors considered during inspections are construction type, type of duct work, age of the home, temperature variations, air quality and energy bills.

The Sealing Process

During the Aeroseal process, a small access hole is cut into the supply or return air plenum and a temporary collar is attached. All mechanical components of the system are temporarily blocked with a foam plug to avoid the entrance of any sealing particles into this equipment. The patented injection machine is connected to the air duct system using a flexible plastic tube, and the Aeroseal system injects adhesive particles into the air duct system which attach directly onto edges, holes and cracks, effectively sealing the duct without coating the inside.
