DuctMasters is about providing
customers with the cleanest air
possible in your home or office.
Air ducts will become dirty over
the years and shouldn't be
ignored.
Quick facts:
"1 out of every 6 people who
suffer from allergies do so as a
direct result of the fungi and
bacteria in the air duct
systems." (Better Health
Magazine)
"Most people spend 90% of
their time indoors." (American
Lung Association)
"Children are more likely than
adults to be affected by
polluted indoor air." (Dept. Of
Consumer Affairs)
"The average 6 room house
collects 40 pounds of dust a
year." (Discover Magazine)
"Typical fiberglass furnace
filters are less than 7%
efficient." (ASHRAE)
Considering that we spend so
much time indoors, it makes
perfect sense to clean the
source of our indoor air quality
problems... our air ducts.
Do you have an indoor
air prolemt:If you
answer "Yes" to any of
the following questions, your
home may suffer from: "Indoor
Air Pollution".
Do you have an air
circulating system that utilizes
a standard fiberglass filter?
Do you have pets?
Are there smokers in the house?
Does anyone in your house
suffer from allergies, athsma,
or other respiratory problems?
Do you regularly clean
excessive dust accumulations
from your household furniture?
Do you experience headaches,
nausea, burning sensations in
the nose, throat or eyes when
inside the home?
Do you have "dust trails" or
discoloring coming out of your
air duct registers?
When you last changed your
furnace filter, did you see dust
and dirt inside the filter
housing?
Dirt, dust, mold, pollen, and
animal dander are recirculated
through our air ducts every time
we turn on our heat or air
conditioner. Combine this with
the moisture and you have an
ideal breeding ground for fungi,
germs, and household mold.
Studies have confirmed that some
diseases, including salmonella,
strep, and legionnaires disease
are spread by contaminated air
ducts.
-Common sources of
airborne contaminants include:
-
Indoor contaminants. These
include chemicals used in
the construction or
renovation of buildings
(e.g., glues, off-gassing
from carpets, emissions from
particle board, cleaning
compounds). In addition,
appliances that burn gas can
produce particulates and
carbon monoxide. Incomplete
combustion and poor
ventilation of these
appliances (cook stoves, gas
furnaces, gas boilers, and
gas water heaters) can
contribute to indoor
contaminants. Gas cook tops
should be used with fans
that send exhaust outside.
Gas-fired heating appliances
should be sealed and
power-vented systems
installed to remove products
of incomplete combustion.
Wood-burning stoves can also
create particulates and must
be vented outside.
-
Outdoor contaminants.
Outdoor particulates can be
drawn inside when the
heating or cooling system
draws air into a home.
Particulates and allergens
found in outdoor air can be
asthma
triggers. Filtering incoming
air for HVAC systems
effectively filters
particulates. Experts
recommend using filters with
a MERV 6-8, but higher MERV
levels trap smaller
particles and generally are
more appropriate for those
with allergies or where the
indoor environment has a
high concentration of mold
spores, dust particles, or
other allergens.
Two types of ventilation can
help control harmful air
contaminants and humidity: spot
ventilation and dilution
ventilation. Spot ventilation
draws air from a particular
location (e.g., bathroom,
kitchen) and exhausts it to the
outside. Dilution ventilation
address low-level contamination
throughout the home.
Spot Ventilation. Exterior
exhaust fans should be installed
in all bathrooms and kitchens.
These fans remove humidity and
carbon monoxide. The most
effective fans are quiet and
durable. Use fans that operate
at one sone or less and exhaust
to the outdoors. Fans equipped
with timers or de-humidistat
controls are useful to ensure
the fans run for a sufficient
period of time. A good rule of
thumb is to run a bathroom fan
for about 45 minutes after a
shower.
Dilution Ventilation. Dilution
ventilation addresses the entire
living space. Air changes
(exchanging indoor air with
outdoor air) and air cleaning
help determine the effectiveness
of dilution. Air changes result
from a combination of natural
ventilation (infiltration;
leakage; windows) and mechanical
(controlled) ventilation. Air
cleaning occurs when
particulates are filtered and
when air is dehumidified to
remove moisture. The goal is to
provide sufficient changes in
clean air to ensure a healthy
environment. There are several
types of heating and cooling
systems with filtration that can
be installed to accomplish this.
The references below provide
links to helpful technical
resources. A common element
necessary in all systems is duct
sealing, particularly on the
return side (side drawing in the
air). The Air Conditioning
Contractors Association (ACCA)
provides guidance on duct
sealing in its Manual D: Duct
Design (see references below).
-Indoor air pollution:
TheIndoor air pollution, in
homes as well as commercial
buildings, is being recognized
as a serious health problem.
Researchers have discovered the
air pollution inside your home
can be much worse than the air
pollution outside your home.
Most people spend 90 percent of
their time indoors, whether it
be at home, at work, or in a car
traveling.
Sources of Indoor Pollution:
The sources of indoor air
pollution include outside
contaminated air, moisture or
standing water, heating and air
conditioning equipment, personal
care products, smoking, cooking,
house cleaning products,
chemicals released from building
products like paneling or
carpet, and remodeling a home.
What
are dust mites? Dust mites
are living, spider-like
microscopic insects that can
travel through the air and are
too small to be seen. They feed
off dead skin cells from humans
and animals as well as mold
spores, so they are almost
everywhere. Dust mites, like
other biological contaminants,
contribute to poor indoor air
quality (IAQ) and may be a major
cause of days lost from work and
school because they can make you
sneeze, trigger allergic
reactions, cause rashes, watery
eyes, coughing, dizziness,
lethargy, breathing
difficulties, and digestive
problems. Exposure to dust
mites, animal dander, cat saliva
and mold causes about 200,000
emergency-room visits a year for
asthma patients.
Where are dust mites found?
Dust mites are found
everywhere there are humans or
animals, warm temperatures, and
humidity levels above 60%. Mites
have been reported worldwide,
including the continental United
States and Hawaii, southern
Canada, most of Europe including
the Scandinavian countries,
Russia, Asia, the Middle East,
parts of Australia, South
America, and Africa. At least 13
species of dust mites have been
found in house
dust.
Six of these are commonly found
throughout the world.
Home renovations: This is
one of the biggest reasons to
get your ducts cleaned. No
matter what type of renovations
you do this year
drywall,sanding,etc you need to
get your ducts cleaned. Most
contractors work with the
cooling system running or even
sweep excess dirt into the air
returns. There is also cases of
workers leaving their lunch
bags,food and drinks behind in
the air return (this is mostly
found in new home construction)
During renovations the duct
system will not only suffer but
your entire system will been
contaminated. Ductmasters are
expert and specialize in complex
cleaning like nenovations.
