CONSERV-AIR DUCT CLEANING

STATE-OF-THE-ART SOURCE REMOVAL TECHNOLOGY

 The objective of source removal duct cleaning is the removal of all dirt, debris and other contaminants from the ductwork. This is recognized as the only acceptable form of cleaning and decontaminating of air duct systems. The Vacuum Removal equipment is designed to enable duct cleaners to produce this result with minimal access to the duct system.

 A conventional HVAC duct system consists of a supply system of ducts to carry heated or cooled air from the furnace/air conditioner (air handler) to various parts of the home or building, and a return duct system to bring fresh air back to the air handler to be heated or cooled again. The supply network consists of a main duct which carries air to smaller branch runs which carry air to the desired locations. The return network works in reverse.

 The portable power vac in tandem with a specially designed portable air compressor for efficient state-of-the-art source removal duct cleaning. This method enables professional duct cleaners to remove contaminants from all parts of the duct system, regardless of location. Yet it is simple to perform and requires only a limited amount of access holes. It works as follows:

 1. The supply and return networks are “zoned,” or separated, so they can be cleaned separately. 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 vacuum inlet is connected to the plenum with a quick-connect attachment collar. The vacuum is then turned on to create an airflow within the supply ductwork. (See Reverse)

 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 compressor using the special air booster gun. This pushes any dirt or debris into the branch run.

 4.            The branches can then be cleaned by running the forward AIR-SWEEP assembly down each run to push dirt and debris forward into the main run. (The branches can also be cleaned using the reverse AIR-SWEEP if access to the duct is available.)

 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 vac, 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 (See Reverse)

 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 can be cleaned and the motor and blower is air washed.
