You’ll find the backdraft damper near the top of the range hood (where it connects to the ductwork). However, some range hoods also have a second damper, which is located close to the roof or exterior wall where the ductwork ends. If you don’t see a damper in either of these places, you might not have one.

There are several common warning signs that indicate your dryer vent may be clogged. If your clothes are taking longer than usual to dry, the vent could be the culprit. Other signs include the exterior of the dryer becoming very hot during operation, or the dryer shutting itself off due to overheating. You might also notice an excess of lint left inside the dryer or in the lint trap after a cycle, see lint building up around the exterior vent opening, or detect unusual or burning odors. A clogged dryer vent is a serious fire hazard, so if you notice any of these signs, you should stop using the dryer and have the vent cleaned immediately.

The length of an allowable dryer vent varies based on the local building codes and regulations. Typically, the maximum range is 25 to 35 feet. However, if the vent must have any 90-degree turns, you may see a reduction of five feet from the maximum. Some municipalities may have no specific maximum allowable length as part of the code. Typically, installers will run the vent over the shortest possible distance for safety. The dryer vent cleaning cost is less with a shorter vent length as well. 

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.
