Annual Dryer Maintenance: Dryer Vent Cleaning
Clothes dryers are equipped with lint filters, which should be cleaned out after each use. However, particles of lint manage to get past the filter. Over time, lint accumulates in the venting system which will restrict airflow and consequently will cause the dryer work harder and eventually malfunction. Lint buildup is also a fire hazard. The dryer vent pipe should be made of either rigid or flexible aluminum tubing. White vinyl tubing is actually more prone to lint accumulation, and should be replaced. This system should be cleaned professionally at least once a year. However, if you want to try and tackle this task yourself, you should do the following:
Begin by unplugging the dryer. If it is a gas dryer, turn off the gas supply. Pull the machine away from the wall, and vacuum behind and beneath it. Then, disconnect the duct from the back of the dryer, which is usually held on with a ring clamp or duct tape. Using a crevice attachment, vacuum the dryers exhaust duct. If you have flexible aluminum tubing, vacuum it thoroughly, or replace the entire length. Rigid tubing should be disassembled and each section cleaned by pushing a cloth through it. Then, reconnect all the pieces, re-position the dryer, and plug it in. And don’t forget to clean out the exhaust hood mounted on the outside of your house.
