Get matched with top dryer vent cleaners in Sunapee, NH

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.

There are a few things you can look out for that indicate it’s time to clean your dryer vent, including the following:

• It has been a year or more since the last professional cleaning.

• Your clothes are taking longer to dry than usual.

• Your clothes smell musty or burnt when they come out of the dryer.

• You see lint building up around the outside dryer vent cap.

• Your laundry room is unusually hot.

• Your dryer is unusually hot to the touch during operation.

• You notice a kink in or damage to the vent.

While a professional can always help, there are some common plumbing culprits you can check yourself to see if you can find the sewer gas smell. For example, you should check your water traps, sometimes called P-traps and S-traps, which are located under sink, shower, and laundry drains. The wax ring beneath the base of your toilet, which creates a watertight seal with the plumbing, could also have gone bad.
