Get matched with top dryer vent cleaners in Schleswig, IA

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.

You will know if your dryer is overheating by placing your hand on top to feel its temperature. If it’s hot to the touch, that’s a clear sign the dryer is overheated. Other signs include your laundry coming out hotter than usual, a burnt smell when it’s running, or burn marks on your laundry.

You might have dampers if you have a ducted heating and cooling system. To find out for sure, find the main trunk line on your HVAC unit, then look for levers or handles on the ductwork. Contact a local HVAC professional if you can’t find any dampers or want to install some.

Depending on how much you use it, your dryer should be disinfected about every six to 12 months, especially if you see frequent buildup of lint or evidence of stains from fabric bleeding or ink. 

Other signs you should sanitize your dryer more often are overheating, improper drying, excessive humidity, or if you notice a strange odor when it’s running.
