The power vacuum/air sweep method involves a powerful large diameter vacuum hose generally ranging in diameter from 8” 12” that moves anywhere from 3000 CFM – 26,000 CFM cubic feet per minute of negative air draw depending on the type of power vacuum machinery being used. Typically speaking, having power vacuum machines that moves anymore that 10,000 CFM is foolish, considering the fact that all ductwork is rated for a set amount of CFM based on the size of the ductwork through external static pressure ratings, velocity and ambience. I do have to admit that the more power a vacuum has, the cooler it is to witness, though. The power vacuum hose is typically installed into the ductwork via a circle cut out which allows for the power vacuum to put the entire side of the ductwork under a complete and sound vacuum draw. By doing so, every vent attached to the ductwork will have a centrally created vacuum present for proper system containment. From there, various mechanical brushes are sent down the rounds to break and push all debris down to where the power vacuum is sucking. Afterwards compressed air ranging from 150 psi – 250 psi air washes anything left by the brushes, to thoroughly and completely clean the round. Once all of the supply/heat pipes are cleaned a variety of different brushes, air whips and blow back jetters are employed to source remove all of the bulk matter back towards the power vacuum. This method of cleaning is superior for actually ridding the ductwork of all loose contamination because there is typically no cleaning obstacles presented by the ductwork that the self propelled mechanical and air tools can’t over come, as well as the fact that the sheer power of the vacuums not only effectively keeps all the debris contained, but has enough power to pull this debris out of the system. Most thorough mode of cleaning where a positive effect such as increased HVAC system efficiency is realized, increased airflow from supply rounds is realized, less HVAC equipment parts failure is realized or increased part lifespan occurs elimination of foul odors presented by isolated incidents where dead animals are presented, animal liquid and solid excretions occur and odor emitting mold/mildew and bacteria occurs and in some cases dust reductions are noticed depending on the amount of contamination that is present in a ventilation system. After this method of cleaning is performed, assuming that the occupant maintains that furnace filter I previously mentioned to manufacturer recommendations, then cleanings may only need to be performed every 3 4 years or even longer if you invest in a high media filter unit.
