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. This method of cleaning is the safest form of cleaning in ensuring a reduced amount of mishaps and or errors at a jobsite occurs. Typically speaking, a company will use a glorified shop vac, various carpet cleaning hose attachments in conjunction with carpet cleaning machinery and or even a glorified shop vac with a spinning brush. Most contact cleaning companies will spend 30 minutes to 2 hours in attempting to reach as much ductwork
that a person is physically able to reach. A small minority of contact cleaning companies will even make a good go at it and will spend up to 8 hours at an average residential jobsite. It is even fair to say that if a contact cleaning company spent all day, if the ductwork was completely exposed and if the ductwork was small enough, a contact cleaning company could technically perform a thorough job if the technician was motivated to perform a thorough job. The contact cleaning method of air duct cleaning is very limited in what dirt, dust and debris is actually pulled out of a ventilation and or HVAC system. 2” diameter vacuum hoses cannot suck up 3” diameter beer cans or soda pop cans. Due to the laws of physics in that a 2” diameter vacuum hose leaves behind all large diameter items, no airflow improvement is ever realized after the service is performed. Clumsy shop vac hoses usually cannot effectively clean through most furnaces burners, hence the ash, dirt, carbon and dust that can be found in these burners typically stay in the burners.
