It is important to clean the dryer properly to make sure that all the lint is removed. First, unplug the dryer from the electric outlet. Clean the exteriors first using a moist microfiber cloth. Open the dryer and clean the accessible parts. Pull out the lint filter or trap and wash under running water to remove lint and other dirt. Clean the drum and check for any lint, fabric fibers, or any item that may have fallen off of pockets. Deep clean the inside of your dryer. This may require a lot of effort but it will be necessary since a lot of lint builds up within. Move the dryer away from the wall and remove the vent tubing behind it. Remove any lint you find. Some are caught in the walls of the tube. If your tube is made of a foil-like material and removing the lint is difficult, might as well replace that hose. Before reconnecting the hose, reach into the vent and remove lint buildup. You can use a vacuum with a dust attachment to remove all dirt and debris inside. When done with this, reconnect the hose back into place, and push the dryer back into place.
A dryer vent must lead outdoors to expel heat, moisture, and exhaust gases outside. Some people think that it would be a good idea to vent indoors and recycle the heat but it is not. The air that flows through the dryer vent contains moisture, which can induce the growth of mold and mildew, and lint particles, which could be dangerous if inhaled, especially for those with asthma and allergies.
The range of cost for a dryer vent cleaning service is between $90 to $160. The actual cost may vary depending on the severity of the clog, the location of the dryer and its vent, and other additional services that may be requested, such as repairs and parts replacement.
Lint, dirt, and other debris can build up in the dryer vent. When left uncleaned, it could restrict or completely block the path for moisture, heat, and exhaust gases to be expelled. It could affect the performance of the dryer and the quality of the air indoors because of carbon monoxide can’t flow through the dryer vent. A clogged dryer vent is also a fire hazard. About 3,000 household fires yearly are caused by dryer vents filled with lint.
The recommended frequency is yearly but it actually depends on how often you use the dryer. If you dry about four to five loads per day, lint buildup would be faster so schedule a dryer vent cleaning every 6 months. If you dry the same load but on a weekly basis, a yearly cleaning would suffice.
