Imagine waking up to see that your house is on fire—and then to find out later that the fire could have been easily prevented. The culprit: Your clothes dryer! According to the National Fire Protection Association, this common household appliance was the cause of more than 15,500 U.S. home fires in 2010.
Lint and other debris can build up in your dryer hose and vent duct, reducing air flow, backing up exhaust gases and eventually creating a fire. These hazards can be avoided by thoroughly inspecting and cleaning your dryer vent every year. (This is particularly true if your dryer vent duct was not designed or installed properly.) Not only are you reducing the risk of fire, you’re also putting money back into your wallet by improving the dryer’s efficiency.
So how do you know if your dryer vent system is clogged and perhaps a ticking “time bomb”? Check out our list below of 5 Warning Signs that it’s Time to Clean Your Clothes Dryer Vent.
1. Drying time for clothes takes longer and longer.
When a dryer vent is clogged, the drying cycle can double or triple in time. You’ll notice that clothes are not completely dry at the end of a regular cycle. A dryer is designed to push out the hot moist air for clothing to dry. If your vent is blocked by lint, the air will stay in your dryer keeping your clothes hot and moist. And when it takes twice as long to dry clothes, your dryer runs longer, putting more wear and tear on it and therefore cutting the machine’s life in half.
2. Your clothing and the outside of the dryer are very hot.
Do you notice that your clothing is very hot at the end of a cycle or the dryer is hot to touch? This warning sign means the vent is not exhausting properly. If your system is clogged, it not only wastes energy, but can cause the heating element and blower in the dryer to wear out faster.
3. You notice a burning smell.
When you run your dryer do you smell a burning odor? Lint, which is very flammable, can build up in the exhaust tube, lint trap and even in the drum casing. If it gets too hot, it can catch on fire, causing a burning smell. (Remember to empty the lint trap often). Discontinue use of your dryer and have it inspected as soon as possible.
4. The vent hood flap doesn’t open properly.
Another visual red flag that you’re due for a cleaning: You can see lint or debris around the dryer hose or outside vent opening: or the duct hood flap does not open as it is designed to do. An outside vent that doesn’t open when the dryer is running means air flow has been restricted due to lint buildup.
5. It’s been longer than a year since your last inspection.
Dryer vent ducts should be inspected at least once a year to reduce the risk of fires and carbon monoxide poisoning. If you hire a professional to clean your vent, expect to pay between $75 to $150, depending on the length and location of the vent. If the exterior exhaust vent is easily accessible, you can try cleaning it yourself with a brush kit.
You’ll find a myriad of how-to online videos, such as this one at YouTube that shows the process with a brush system. Some of the DIY cleaning kits do not always properly clean the vent duct. One advantage to hiring an experienced professional is he or she has likely seen just about every make and model of dryer and has the appropriate brush and equipment to effectively do the job.
If you’ve tried cleaning your vent system and still have the above issues, then it could mean you need to have your vent rebuilt or repaired. Lint should not build up in your dryer if your duct system is properly designed and installed. If you haven’t had your system inspected and cleaned for several years, be proactive and get it done today! Did we miss any other signs that it’s time to clean your dryer vent?
