5 Questions to Ask About Dryer Vent Cleaning

If your clothes are taking longer to dry and you find yourself pressing the cycle button several times to dry a single load of clothes, you may have a clogged dryer vent. Blocked dryer vents can lead to fires if not cleaned, making it important to stay on top of routine dryer maintenance. These dryer vent questions can prepare you for a talk with a pro so you can get your unit running safely and effectively again. 

Where are the dryer vents located? 

Most dryer vents are located behind the dryer, level with the unit’s height. This helps prevent humidity and dust buildup. The shortest path to an exterior wall is the best location for a dryer vent, but not every dryer has traditional ventilation. Some homes might have a basement, attic, roof, or window ventilation system. 

When do you need your dryer vents cleaned?

Dryer vents need cleaning one to two times yearly to stay on top of clogged vents. The best time for dryer vent cleaning is during the spring or fall. It’s easier for a professional to clean your dryer vents in mild climates rather than in the dead of winter or scorching summer heat. Winter and summer mean dryer air and higher heat, both of which can increase fire risks from a clogged dryer vent.  

What type of dryer system needs cleaning?

There are several types of dryers that operate using gas or electricity. Both gas and electric dryers require occasional cleaning, but ventless dryers don’t have vents and won’t need vent cleaning services. You’ll still need to clean the lint trap after every cycle and clean the condenser once a year.

What is the approximate length of the dryer vent?

Dryer ducts can’t be longer than 35 feet from the dryer and the exterior vent. A 90-degree bend in the vent also decreases airflow, lowering that length by around five feet for every 90-degree curve. 

Ducts are flexible and may move over time, so factor in the length when determining how much you might spend to hire a professional duct cleaner. Most dryer vent cleaning costs fall between $100 and $185, but longer vents and vents in difficult places—like roof dryer vents—may cost more. Getting quotes from several dryer vent technicians will help you budget accurately.

Where is your dryer located? 

Dryers located on the second floor or basement may have unusual or hard-to-reach ventilation systems. If your dryer is in your garage, crawl space, or an interior room without access to an exterior wall, consider hiring a dryer vent cleaner near you to relocate the unit and vent during their service call.
