1.
The supply and return networks are “zoned”’ or separated, so they
can be cleaned separately. This typically done by removing the furnace
filter, inserting it into a plastic bag, and reinserting it into the
furnace.
2
An access hole is cut into the
supply plenum and flex duct from the Negative Air Vac
inlet is connected to the plenum with a quick-connect attachment collar.
The vacuum is then turned on to create an air
flow within the supply ductwork.
3.
Each branch is cleaned separately
starting with the branch furthest from the handler.
The register and boot area are air blasted with compressed air
from the AIR-SWEEP compressor using the special air booster gun. This
pushes any dirt or debris into the branch run.
4.
Each Branch is cleaned separately
by running a Rotor-Whip down down each run to
break loose the dirt and debris
so it is pulled in the main run. The branches
are then swept using a reverse
duct sweeper.
5.
The main run is then cleaned using the reverse
air sweep assembly to dislodge debris
accumulated in the duct. It also pulls the loosened debris backward
toward the portable power vacuum , to be
captured in its multi-stage filtration/collection system.
1” access holes every 25 feet are all
that is needed to use the AIR-SWEEP. This system
wide cleaning process allow us to avoid physically removing your vents
(which often are painted or caulked in place)
6.
Once all the
supply side of the system has been cleaned, the return duct system is
then cleaned using the same method.
7.
At this stage the coil
and the furnace fan are gently air
washed to remove any remaining dirt or debris.
