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.

Exhaust systems should be inspected annually to prevent efficiency loss and address any arising mechanical issues.

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. 

Yes, mold can grow in a wet dryer vent. Mold is a type of fungi, and fungi thrive in warm, moist conditions. Dryer vents need to be aired out so heat can escape and moisture can dry. If your dryer vents aren’t properly vented, the trapped heat and moisture will cause mold to grow, and the mold can spread to the dryer and even your clothes. Not only can this leave a musty smell on your freshly laundered clothes, but—more importantly—it also poses a health risk.
