Aeroseal Duct Sealing FAQs

Frequently Asked Questions about Aeroseal & Duct Sealing

How do I know when I need to get my ducts sealed?

There are several signs to look out for that will indicate that it is time to seal your air ducts. For example, if you find it difficult to adjust the temperature of rooms in your home or business or there has been an increase in your energy bills. You may also see an increase of dust and debris building up. When ducts begin leaking, they can pick up dust and distribute it throughout your home.

If you have noticed any or all of these symptoms occurring, you should call a specialist to inspect your air ducts and to confirm whether they are leaking.

Why do commercial buildings need their air ducts sealed?

Like sealing a home’s air ducts, sealing the ducts within your commercial building will save energy costs, increase the comfort and ventilation levels within the building, and comply with evolving building codes. Sealing the air ducts will also reduce chances of any cross-contamination that may occur between different building zones. For example, sealed air ducts will prevent non-smoking areas from being contaminated by chemicals that result from second hand tobacco smoke that may originate from smoking areas.

Is the sealant safe?

The Aeroseal sealant we use for all of our air ducts is very safe. There is currently no exposure limit set for vinyl acetate polymer (VAT), which is one of the main ingredients of our sealant material, and the other main ingredients have all been reported nontoxic based on years of research.

Does Aeroseal have an odor?

There may be a mild odor for 30 minutes after we leave, but once dry, the material is odorless throughout its lifespan.

How long does the duct sealant last?

The effectiveness of Aeroseal is guaranteed for 10 years and has been tested up to 40 years. The sealant comes with a 10-year warranty and a certificate that verifies the completion of the process.

Do my ducts need to be cleaned before the sealing process?

We highly recommend that our customers clean their ducts beforehand. We will be changing the airflow in the ducts, and if there is light debris still in them, there is a chance it will become airborne when the system is turned back on. If there is heavy debris, we will “gunk up” the ducts with the polymer sealant.
