1. The supply and return networks are “zoned,” or separated, so they can be cleaned
independently. This is 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 the flex duct from the HEPA vacuum
inlet is connected to the plenum with a quick-connect attachment collar. The powerful
vacuum creates high velocity air movement within the supply ductwork to transport loosened
dirt and contaminants out of the ductwork and into the vacuum's filtration/collection system.
3. Each branch is cleaned separately starting with the branch farthest from the vacuum.
The register and boot areas are blasted with compressed air from the powerful compressor
using the special air booster gun to push any dirt or debris into the branch run.
4. The branches are then cleaned by feeding the special forward air tools down each
branch run to push dirt and debris forward into the main run. The branches can also be
cleaned using the special reverse air tools if access to the branch duct is available at the
main supply duct.
5. Agitation devices such as the special brush systems can also used to dislodge caked
on debris from inside duct surfaces.
6. The main run is then cleaned using the agitation devices and the special reverse
assembly to dislodge debris accumulated on duct surfaces. The loosened debris is pulled
backward toward the HEPA portable power vacuum and captured in its multi-stage
filtration/collection system. One-inch diameter access holes need to be cut only every 25 feet.
7. Once the supply side of the system has been completely cleaned, the return duct
system is cleaned using the same method.
8. At this stage the coil, motor and blower, and blower compartment are cleaned.
9. Once the entire cleaning process is completed, all access holes are completely
closed with the efficient one inch plugs and insulated spin doors that seal off any leaking
and make the duct systems easily accessible for repeat cleaning.

The Process:
| Do you notice dust on your furniture shortly after cleaning? Is there a smoker in the house? Do you have pets? Are your registers or vents dirty? Do you have allergies? |
