temperature in rooms throughout your home.

the ductwork of their home.

Q: Can Aeroseal reduce the noise made by the return and supply grilles in my home?
A: If the ductwork is poorly designed or installed, not enough air may be able to pass through
your indoor coil, freezing up your system, and creating a wet, loud and costly problem. If the
ductwork is undersized, the air travels at a faster rate and creates noise. If the return grilles
are undersized, the air travels through the grille at a higher rate of speed and makes noise.

Q: Can Aeroseal reduce the amount of dust in my home?
A: Ductwork runs through attics, crawlspaces, basements, garages, and walls. Leaky return
ducts pull in dust and pollutants, sends them through the furnace, and then out into the living
area of you home through the supply ducts. Aeroseal can reduce the amount of leakage by
as much as 90%, reducing dust and other pollutants from entering your home.
