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.

If your dryer is wet inside, it could be due to a poorly designed ventilation system. This happens more frequently during the hotter months as heat is trapped inside the vent duct. Broken or failing seams and seals on the vent pipe can also allow warm air to enter. If changing the ventilation is not an option, consider insulating your vent pipes to reduce moisture capturing.

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. 

The frequency of cleaning your dryer depends on how often you use it. For regular households, it is recommended to clean the lint trap after each load of laundry. Additionally, thorough cleaning of the dryer—lint trap, drum, and exterior—should be done every few months. It's important to pay attention to the vent system as well. Ideally, it should be cleaned at least once a year, or six months if your dryer takes care of huge loads often, or more frequently if you notice reduced drying efficiency.
