The Aeroseal process does not coat or line the ductwork. The only sealant remaining in the ducts will be at the spot of the leak that was sealed.
This noise is usually the result of two conditions. One is created when the ductwork is undersized and air is rushing through your air duct system. The other condition is caused when a limited amount of air is allowed to flow through the indoor coil of your heating and cooling system. Once the exact problem [...]
Ducts of all material types can be successfully cleaned after they have been sealed with Aeroseal.
Dirty ducts should be cleaned as we can not guarantee that the glue will adhere to dust and debris. We will inspect the ductwork during the Aeroseal estimate.
Aeroseal certified technicians are trained to protect all HVAC systems and accessories prior to sealing. Some items, such as humidifiers or UV lights, may be removed then reinstalled to prevent damage. Others may be bagged or covered.
We recommend that any sensitive electronics be covered while Aeroseal is sealing your ductwork.
Sealant escaping from the ducts will settle in wall cavities, attics or crawl spaces. During the process we will filter the air to capture any sealant entering any living areas.
Broken and disconnected ducts – large leaks – need to be fixed prior to sealing with Aeroseal. If a hidden large leak is uncovered during sealing, the process is stopped and a solution is discussed.
Up to a 5/8th inch round hole can be sealed by Aeroseal.
We prefer that no one is in the house during sealing due to impact on productivity. If you are pregnant, a senior, infant, or utilizing medical equipment we do encourage you to leave as a simple safety precaution.
