Conducting quick dryer maintenance can extend its lifespan. Help your dryer stay in mint condition by cleaning the lint trap before and after every cycle. This keeps leftover lint from accumulating in your dryer vent, which is one of the leading causes of household fires, according to the U.S. Fire Administration.

You can also wipe down the lint screen with dish soap every few months to keep it extra clean. A basic wipedown of the drum every few months and a deep clean of the exhaust vent once a year are beneficial, too. 

As a general rule, you should have your dryer vent professionally cleaned at least once a year to remove lint and debris buildup, which can cause fires and increase energy costs. However, the frequency may need to be adjusted based on usage. If you have a large household, use the dryer frequently, have pets, or have an older vent system, it is better to clean the vent more often, such as every six months or even quarterly. You should also schedule a cleaning immediately if you notice signs of a blockage, such as clothes taking longer to dry, the dryer feeling hot to the touch, or an odd odor. Routine vacuuming is not a substitute for a thorough, professional cleaning.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

Dryer vents commonly need to be replaced every one to three years. This will depend on the rate at which you dry loads, how often you clean your vent, and what type of vent you have. For instance, regular care will prolong the life span of most options, while aluminum foil vents may need to be replaced more frequently with or without regular maintenance.
