WHY DUCT CLEANING?
Since early
man lit his first fire in his first cave, we knew that indoor air quality
would be an important part of our lives. Of course we had no scientific or
engineering based reasons for feeling so, it was just intuitive. . . and
the fact that we choked on the smoke!!!
Even the bible talks of indoor air quality
in “Leviticus – 14” as it describes the ancient methods used to remediate
mold.
Today we can find article after article
in our newspapers or on television that reinforces the importance of good
indoor air quality.
From 1980 to 1994, asthma increased in our
pre-school children by 160 % and in our general population by 75% in the
same time period. We learn more each day about those things that impact
our lives, such as: molds, bacteria, dust mites, cockroach feces, and many
other contaminants that can contaminate almost any portion of our homes
and/or businesses, but there is one area that spreads contamination
quickly. That area is the “lungs” of our home, the heating and cooling
system in your home and work environment!
Although we consume only three (3) quarts
of water each day on average, but we consume fifteen thousand (15,000) to
twenty thousand (20,000) quarts of air each day. You would think we would
do our best to keep that air clean . . . wouldn’t you? That is what makes
“duct-cleaning” so important!
HEART AND LUNGS OF
THE HOME
Contamination of many
sorts can come from almost any part of the HVAC system. Construction
materials and foodstuffs can fall into the floor register in the dining
room. Dusts (mostly organic materials), animal hair, dander, dust mite
particles and feces, mold spores, bacteria, (and almost anything else you
can think of) will be pulled into the return-air side of the system and
will ultimately make its way back to the supply side. There it will be
launched back into the air that you and others around you breathe all day.
Any of it that stays in the system may become the beginnings of severe
mold or bacteria colonization and contamination. In fact, there are two
main “bio-nesting” areas in your system. One is the filter, its job
is to gather and stop as much dust (mostly organic materials) as it is
capable of, because that dust is then circulated through the system.
Keep in mind that
if your filter is even fifty percent (50%) efficient, that just means that
it is letting the other fifty percent (50%) on through to the second
bio-nesting area. The second bio-nesting area is the evaporator coil and
condensate pan. Since this “inside” portion of your air conditioning has
water running over it all summer, as it condenses the humidity out of the
air, it becomes “pollution headquarters”.
Air,
containing dust, mold spores, bacteria, and more is blown over the wet
evaporator, where the combination mixes into the perfect mold growth
mixture. A combination of loose furnace panels, unsealed ductwork, and
inadequate filtration adds food source and contamination to those
bio-nesting areas, every day! After a few years, the buildup can become
significant enough to be a possible health issue for many unsuspecting
people!
THE SOLUTION
To alleviate the problem you must start by removing the
source of that problem. In other words, you must have the heating and
cooling system thoroughly cleaned.

regarding Duct Cleaning
Sounds easy enough, however, proper
duct-cleaning has become far more thorough and complete than the majority
of duct-cleaners are willing to provide these days. Proper duct-cleaning
will involve a well trained company, using modern equipment, and
thoroughly cleaning the entire system – including the blower, the heat
exchanger, the interior of the furnace cabinet, and the evaporator coil
and condensate pan. Further, it will inevitably take two men most of a day
to do it properly.
Locating a company that is NADCA (National
Air Duct Cleaners Association) certified is the first important step.
NADCA was originally formed to overcome “less professional” organizations
by combining the best in the industry for the purpose of providing
standards, training, and certification for the benefit of the public.
Continuing education requirements insures that members stay current in
their training so as to continue providing the highest quality service.
Next is to apply common sense as a company
does the cleaning. Remember that it should take two men most of a day to
properly clean a system. If they come in and “hurry” their way through it
too quickly – they’re probably not going to do a good job as well.
What kind of heating system/ventilation system do you have?
Do
you have air conditioning?
How
often are air cleaners in use?
How
often are air filters changed or cleaned?
Are
special filters such as electric precipitators used?
These questions may vary or be left out according to local practices in
different climatic conditions.
