Will all the insides of my ductwork be coated with sealant?
No. Our formula doesn’t coat or line your ducts. The only sealant remaining after the Aeroseal technician is done will be over the leak that was sealed.
How long will it last?
Guaranteed for three (3) years in commercial applications (ten years in residential). Based on testing, the sealant has an expected life of at least forty (40) years.
Is the sealant safe?
The sealant is non-toxic and has been used in hospitals, schools, surgery centres, and government facilities all over the world for the past twenty years. It has been tested by an independent lab and found to have an extremely low concentration of VOCs, during sealing time only. The primary component has no OSHA maximum exposure limit.
What is the sealant made of?
The primary component is Vinyl Acetate Polymer, which is used in water based paints, hair spray, and chewing gum.
How long does it take to dry?
Drying time is less than two (2) hours.
Will my building smell?
There is a mild odor during sealing (similar to Elmer’s Glue) which will dissipate by the next day (if not before)
How big of a leak can be sealed?
Up to a 5/8″ hole can be sealed during the normal range of sealing productivity.
What about leaks that are too big?
Broken and disconnected ducts and large leaks need to be fixed prior to sealing. As a turn-key solutions provider, Aeroseal dealers could potentially provide our services in solving these problems for your project needs.
Where does the sealant leaking from the ducts go?
Sealant escaping from the ducts will settle in wall cavities or crawl spaces. During the process, we will filter the air to capture any sealant entering the living areas.
Will it harm electronics?
We recommend sensitive electronics be covered.
What about my HVAC accessories?
Technicians are trained to protect all accessories prior to sealing. Some items, such as humidifiers or UV lights, may be removed then reinstalled to prevent damage; others may be bagged and covered.
Do ducts need to be cleaned before sealing?
Extremely dirty ducts should be cleaned. We recommend the technician assess the condition of the ducts prior to sealing.
Can I clean my ducts if they are sealed?
Ducts of all material types can be successfully cleaned after sealing.
Will the ducts be covered with sealant?
The Aeroseal process does not coat or line the ductwork. The only sealant remaining in the ducts will be at the previous leak.
