Can Aeroseal fix my hot or cold rooms?
By sealing your ductwork utilizing the Aeroseal technology you can expect air to be delivered where it is designed to go and not into your not basement, attic, or crawl space. This reduces hot or cold spots in rooms and between floors.
Can Aeroseal reduce the amount of dust in my home?
Ductwork runs through attics, crawlspaces, basements, garages, and walls. Leaking return air ducts pull in dust and other indoor air pollutants and sends them to the central heating and cooling system. From there they are sent to the living areas of your home. The Aeroseal air duct sealing system can reduce the amount of leakage by as much as 90%, reducing dust and other indoor air pollutants from the conditioned air in your home.
How much will Aeroseal save me in energy costs?
Some homeowners have saved up to 40% on their energy bill. Naturally, exact savings are difficult to precisely estimate since they depend on a multitude of variables such as your weather, house condition and design, your heating and air conditioning system, system usage – as well as other factors like energy prices.
What does the Air Duct Diagnostic and Inspection tell me?
Inspection discovers any obvious break in the duct work and, as the initial step of the sealing process, the Aeroseal system will establish an exact amount of leakage in the duct system. Of course, many people already know that a room or two in their house doesn’t get good air circulation because they can feel it. Or, they already know that their energy bill is high because they see it. The diagnostic measurement, provides a scientifically valid means to understand the performance of your air duct system. Many people are surprised to learn that homes typically leak 30% to 40% or more of their air through air duct leaks.
How long does Aeroseal last?
Aeroseal is guaranteed for 10 years and stress tested for 40 years in residential applications.
Will my house smell after Aeroseal?
There is a very mild odor similar to Elmer’s Glue during the sealing process. The odour will dissipate completely by the next morning – but usually before.
Is the sealant used in Aeroseal safe?
Sealant used by Aeroseal is non-toxic and has been used in hospitals, surgery centers, and government institutions. UL approvals for UL 1381 for aerosol based technology – UL 723 for smoke and flame rating of 0 and UL 181 for mold growth. Primary component is Vinyl Acetate Polymer, used in water based paints, hair spray, and chewing gum.
How long does it take for Aeroseal to dry?
It only takes around 2 hours for Aeroseal sealant to dry.
What VOCs are emitted by Aeroseal?
The sealant used by Aeroseal has been tested by an independant lab and found to have extremely low concentration of VOC’s during sealing time. The primary componont has NO OSHA maximum exposure limit.
Should I be in the house during the Aeroseal application?
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.
How big of a leak will Aeroseal seal?
Up to a 5/8th inch round hole can be sealed by Aeroseal.
What about leaks that are too big?
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.
Where does the sealant leaking from the ductwork go?
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.
Does Aeroseal harm electronics?
We recommend that any sensitive electronics be covered while Aeroseal is sealing your ductwork.
Does Aeroseal harm my HVAC system/accessories?
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.
Do ducts need to be cleaned prior to sealing?
Extremely dirty ducts should be cleaned. We recommend that the technician assess the condition of ducts prior to beginning to Aeroseal process.
Can I clean my ducts if they are sealed by Aeroseal?
Ducts of all material types can be successfully cleaned after they have been sealed with Aeroseal.
Will the insides of my ductwork be covered with sealant after Aeroseal?
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.
Can Aeroseal reduce the noise made by the return and supply grilles in my home?
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 has been identified, your contractor can provide the best solution for noise reduction.
