Duct Cleaning Simi Valley in Ventura, California For Sale
Type: Cleaning, For Sale - Private.
The procedure we use to clean air ducts is called the
"positive-negative method" and is described below (the procedure
may vary slightly per job depending on the configuration of the
duct work):
Cut an access hole in the main duct work, and attach a negative
air machine to the hole. Remove the vent covers in the home/property.
Clean the grill/diffuser (opening to the air duct) and clean inside
the vent using a HEPA filtered backpack vacuum. After cleaning is
complete, each vent cover is plugged with foam to ensure that
debris does not flow through a vent opening during cleaning and
creates a powerful negative air pressure inside the duct work after
the vacuum is turned on.
Turn on the negative machine. Go to the vent furthest away from the
main system and pull out the foam plug. All force will go to that vent.
Then, an agitator is introduced into the vent opening to dislodge all
debris from the walls of the duct work. Method of agitation varies
depending on the size and type of duct work and includes spin brushes,
and air operated whips. (Note: the furnace will be zoned off so no
debris will be pulled through the system).
This agitator supplies approximately 200 pounds per square inch of
compressed air, and is used to push all the debris to the vacuum
while the vacuum is pulling. This is frequently called the "positive-
negative" method and is the way NADCA mandates that duct cleaning be
performed. The return duct work is cleaned in mostly the same way.
However, often times the return duct work is wide enough to allow us
to use hand brushes and vacuums in addition to agitation.
