monitored burglar alarms
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. Also if any home security wiring
, telephone wires or low voltage wiring is ever present in the ductwork, the physical nature of the contact cleaning method in air duct cleaning will increase the chances in breaking such wires, whereas air washing will not compromise such wires in any shape way or form.
