Most ventilation and or HVAC systems have portions of ductwork that is not easily accessible due to portions of the ductwork being drywall finished around. Should this be the case at any given
jobsite, a consumer and or customer must realize that a large portion of ductwork will not be cleaned as a result when the contact cleaning method of air duct cleaning is employed. Typically a shop vac hose can only reach up to 15’ before
the hose just curls up. Some trunk lines may stretch out to over 100’ in distance, which means 15’ would be cleaned and 85’ would go untouched. 90 degree turns will almost always make the shop vac end its descent in cleaning down a pipe because the shop vac hose cannot be turned without physical intervention. A greater risk of disconnecting pipes occurs due to the physical nature of the contact cleaning method.
