- Clean the air conveyance system using Abatement’s AIRE-SWEEP® Compressed Air Tools and DUCT-PRO® Mechanical Agitation Brush System to dislodge dirt and other contaminants from the ductwork and other HVAC components.
- Use a powerful Abatement HEPA-AIRE, HEPA-filtered Portable Power Vacuum to place the section of the duct system being cleaned under negative pressure, pull dislodged contaminants out of the duct system and capture them.
- Place neoprene runners on all areas of carpet and other flooring material that we will be walking on.
- We place carpet mats in front of vent openings, to ensure that we are not going to spill dirt from your dirty vents onto your clean floors.
- We cover beds and other furniture adjacent to air vents with plastic.
- We place plastic corner protectors throughout your home to ensure that we do not damage any walls during our cleaning process.
- 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.
- An access hole is cut into the supply plenum and the flex duct from the HEPA-AIRE 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.
- 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 AIRE-SWEEP Compressor using the special air booster gun to push any dirt or debris into the branch run.
- The branches are then cleaned by feeding the Forward AIRE-SWEEP Assembly down each branch run to push dirt and debris forward into the main run. The Reverse AIRE-SWEEP Assembly can also be used to clean branch runs if access at the main supply duct is available.
- Agitation devices such as the AIRE-SWEEP Power Brush, Duct Whip or Power Rod System are used when needed to dislodge caked on debris from inside duct surfaces.
- The main duct run is then cleaned. First, one-inch diameter access holes must be cut into the duct every 25 feet. Then, the Agitation Devices and an AIRE-SWEEP Assembly are used to dislodge debris accumulated on surfaces. The loosened debris is pulled or pushed toward the HEPA-AIRE Portable Power Vacuum and captured in its multi-stage filtration/collection system.
- Once the supply side of the system has been completely cleaned, the return duct system is cleaned using the same method.
- The coil, motor and blower and blower compartment can be cleaned.
- Once the entire cleaning process is completed, all access holes are completely closed with the efficient CAPLUGS® and cover plates are installed over the access holes.
