There are a number of benefits associated with cleaning your air ducts.

Before the sewer work begins, a technician drills a large hole in the trunk of the furnace. The hole is covered and fastened with a large vacuum tube. A powerful vacuum cleaner is attached to the pipe and is used to remove dirt and debris from the ducts.


A small hole is drilled in the oven and a long handle brush is used to poke through the channels and remove any remaining debris. There are a number of objects that can get into an air duct, causing clogging that affects the productivity of the cooling and heating systems. A scoping camera is used to find blockages so that they can be removed. If the obstruction is severe, the duct may need to be dismantled for removal.


After cleaning the channels and clearing any blockages, the vacuum is disconnected from the furnace box and the plastic bags are removed from the vents. The sewer cleaning process is completed by carefully plugging any holes that have been made to keep them airtight. Any ducts that were taken apart to clear clogs are put back together and the hole in the stovepipe is patched with a large metal plate.
