Q: What size of holes can be sealed using the Aeroseal air
duct sealing process?
A: Holes and cracks up to 5/8th
of an inch wide can be completely sealed.
Q: What does the Air Duct Diagnostic tell me?
A: Basically, the diagnostic
measures air duct leakage and shows you the precise
temperature of all air registers. 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, tests and reports provide 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. The diagnostic objectively shows this.

testing, click here.]
Q: What are the estimated savings?
A: A series of government
reports have shown that air duct sealing can lead to up to
$300 in energy savings per year. 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. To give
you an approximate idea of what is normal, we can provide
typical case study examples.
One house in Spartanberg, South
Carolina provides a typical example (see
other case studies). In this case, the house was a 2-story
3200 square foot home made in the late 1960s. Aeroseal air
duct sealing reduced
the homeowner’s air duct leakage by 91% providing a savings of
$273 per year.
Also, all Aeroseal air duct certified
technicians are qualified to run a program made by the
Environmental Protection Agency (EPA) called “Duct Investor”.
Duct Investor takes a comprehensive list of variables and
provides a homeowner with the best available estimate of what
they should realize in cost savings.

Q: In a nutshell, how does an Aeroseal air duct seal work?
A: Basically:
1. Preseal test to measure the
leakage as a baseline for measuring progress.
2. Aeroseal air duct sealing
a. Block off the registers with foam or plastic.
b. Pump an aerosol into the duct system.
c. Since the air has no place to go except out through the leaks (the
registers are blocked), the sealant material is deposited
precisely at the air duct holes where leakage occurs.
d. A computer and sensors are used to measure and control the progress.
The technology is patented from the University of California
and the process is endorsed by the Environmental Protection
Agency.
3. Postseal test to measure
improvements.
4. Room airflow measurements to
verify improvements.
5. Complete report
that is printed
on the spot to provide a record of improvements.

Q: Does
the air duct sealing material become brittle?
A: The vinyl sealing material
remains rubbery, never cracking.
Q: How
long will the air duct sealing material last?
A: The sealing material
has been found in rigorous testing to last over 10 years without
failure.
Q: Do
air ducts need to be cleaned before air duct sealing?
A: It's likely that the
holes and cracks in the ductwork have allowed dust and other
particulate matter to enter the system. If you are experiencing
extensive levels of household dust, this might be the reason.
Your Aeroseal contractor can advise whether it will be necessary
to clean your ductwork prior to sealing.

duct cleaning, click here].
Q: Does
the sealant coat the inside of the ductwork?
A: The sealant only sticks
to the holes in the air duct without coating the rest of the
duct.
Q: Is
the sealing material used by the Aeroseal air duct sealing system safe?
A: The vinyl polymer is
safe, using the same base material as used in chewing gum
and is UL tested and approved. [For
more info on safety, click here.]
Q: Does
the sealant leave an odor?
A: The Aeroseal air duct sealing
process leaves no lingering odor, and since the material does
not put off gas over time, there will be no odor for the life
of the product.
Q: If
the rooms of my home have inconsistent temperatures, can
Aeroseal improve the performance of my heating and A/C system(s)?
A: The Aeroseal sealing
system can help improve the comfort of your home by reducing
the difference in temperature levels throughout your home.

Q: Can
the Aeroseal air duct sealing system help reduce my utility bills?
A: Some homeowners have
saved up to 40% of their energy bills after having the Aeroseal
air duct sealing system seal their central air duct system.

Q: Can
the Aeroseal air duct sealing system reduce the noise made by the return
and supply grilles in my home?
A: 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. Both problems can be identified during
the diagnosis process of the Aeroseal sealing system process.
Once the exact problem has been identified, your contractor
can provide the best solution for noise reduction.

Q: Can
the Aeroseal air duct sealing system reduce the amount of dust in my
home?
A: 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 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.

Q: Is the sealing
guaranteed or can I get my money back? What if it doesn't
work?
Aeroseal provides a 10-year
warranty on the seals
created with our process. We have enormous confidence in the
quality of our seals since they are based on Lawrence Berkeley
National Laboratory research and a patent through the
University of California. The EPA has endorsed Aeroseal, as
have numerous local energy utilities. Note: the warranty is
for on-site seal failures and does not cover additional damage
(e.g. an electrician that steps on a duct while running
wiring), wear or tear (i.e. the shelf life of a plastic duct
is passed, rodents eat into a duct, or a duct rusts out), and
subsequent replacement of failed ducting.
Overall, in the 9000 plus seals done to
date, we have yet to receive any warranty claims.
