Learn as much as
possible about air duct cleaning before you decide
to have your ducts cleaned by reading this guidance
and contacting the sources of information provided.
|
| |
|
|
|
Consider other
possible sources of indoor air pollution first if
you suspect an indoor air quality problem exists in
your home. |
| |
|
|
|
Have your air
ducts cleaned if they are visibly contaminated with
substantial mold growth, pests or vermin, or are
clogged with substantial deposits of dust or debris.
|
| |
|
|
|
Ask the service
provider to show you any mold or other biological
contamination they say exists. Get laboratory
confirmation of mold growth or decide to rely on
your own judgment and common sense in evaluating
apparent mold growth. |
| |
|
|
|
Get estimates from
at least three service providers. |
| |
|
|
|
Check references.
|
| |
|
|
|
Ask the service
provider whether he/she holds any relevant state
licenses. As of 1996, the following states require
air duct cleaners to hold special licenses: Arizona,
Arkansas, California, Florida, Georgia, Michigan and
Texas. Other states may also require licenses.
|
| |
|
|
|
Insist that the
service provider give you knowledgeable and complete
answers to your questions. |
| |
|
|
|
Find out whether
your ducts are made of sheet metal, flex duct, or
constructed of fiber glass duct board or lined with
fiber glass since the methods of cleaning vary
depending on duct type. Remember, a combination of
these elements may be present. |
| |
|
|
|
Permit the
application of biocides in your ducts only if
necessary to control mold growth and only after
assuring yourself that the product will be applied
strictly according to label directions. As a
precaution, you and your pets should leave the
premises during application. |
| |
|
|
|
Do not permit the
use of sealants except under unusual circumstances
where other alternatives are not feasible.
|
| |
|
|
|
Make
sure the service provider follows the National Air
Duct Cleaning Association's (NADCA) standards and,
if the ducts are constructed of flex duct, duct
board, or lined with fiber glass. |
| |
|
|
|
Commit to a
preventive maintenance program of yearly inspections
of your heating and cooling system, regular filter
changes, and steps to prevent moisture
contamination. |
