dryer vent

Dryer vent cleaning removes the buildup that results from the lint that escapes through the lint trap.  Lint can build up in the duct and narrow the passage of hot air outwards. .  This buildup therefore causes inefficiency in your dryer’s operation, extends drying time, and raises energy costs. Hence, a clogged dryer vent duct can become a fire hazard.
There are different methods for cleaning air ducts:

 

Negative pressure method vacuums loose debris out of the dryer vent. This is done through the connection point between the dryer and the duct.

First, a brush is inserted into the duct via the connection point behind the dryer. Next, the brush loosens the lint from the walls of the duct.  Finally, a vacuum removes the loosened lint.
