Dryer vent cleaning might not be the first thing on your to-do list, but it’s a critical part of home maintenance that can save you money, extend the life of your dryer, and even protect your family’s safety. Over time, lint and debris can build up in your dryer vents, restricting airflow and increasing the risk of a house fire. The U.S. Fire Administration reports that clothes dryers are responsible for thousands of house fires annually, with failure to clean the vent being a leading cause.
Ignoring your dryer vent could lead to more than inconvenience—it could put your home at risk. So how do you know when it’s time for a professional dryer vent cleaning?
Your Clothes Take Longer Than Usual to Dry
One of the most common signs that your dryer vent needs cleaning is when your clothes aren’t drying properly. If you have to run your dryer two or three times for a normal load, the vent may be blocked. A clogged vent restricts hot air from escaping, which means your dryer works harder and longer to dry your clothes.
Running your dryer multiple times per load isn’t just frustrating—it also consumes excess energy. According to Energy Star, reducing drying time improves efficiency and saves on utility bills. If you notice longer cycles, it’s time to check the vent.
Burning Smell or Excess Heat
Have you ever noticed a burning smell when the dryer is running? That odor could be lint getting too hot in the vent system. Lint is extremely flammable, and if it’s near a heating element or motor, it could ignite. This is a serious red flag and should never be ignored.
In addition to strange smells, your laundry room may feel unusually warm when the dryer is on. That’s because hot air that should be venting outside is being trapped inside. This not only increases the fire risk but also makes your HVAC system work harder to keep your home cool.
Visible Lint Around the Vent Opening
Take a look at the outdoor vent flap while your dryer is running. If little or no air is coming out, that’s a clear sign of a blockage. You may also see lint buildup around the vent cover or on the ground nearby.
Routine visual inspections are a good habit, especially if your vent exhaust is low to the ground or in a frequently used part of your yard. A clean and functional vent will have strong airflow and minimal lint residue around it.
Increased Allergies or Dust Indoors
Believe it or not, a clogged dryer vent can contribute to poor indoor air quality. Lint, dust, and allergens may recirculate through your home, especially if your venting system isn’t properly sealed or has been compromised. This can trigger allergy symptoms, sinus problems, or even respiratory irritation.
The EPA recommends maintaining your HVAC and exhaust systems to improve air quality indoors. If you’ve been sneezing more or noticing more dust than usual, your dryer vent could be a hidden source of the problem.
Your Dryer Is Overheating or Shutting Off
Modern dryers are designed with built-in sensors to prevent overheating. If your machine is shutting off mid-cycle or becomes hot to the touch, it may be activating a safety mechanism due to restricted airflow. These auto shut-off features are there to prevent fires, but they also indicate that your system needs attention.
An overheating dryer not only risks damage to the machine but also shortens its lifespan. Scheduling a vent cleaning now could save you the cost of replacing an entire unit down the road.
You Haven’t Had a Cleaning in Over a Year
Even if you haven’t noticed any of the symptoms above, you should still schedule a professional cleaning at least once a year. This is particularly important if you use your dryer frequently or have a long or winding vent system.
Some households may require more frequent cleanings—such as homes with multiple pets, large families, or older venting systems. Proactively maintaining your vent ensures safety, reduces energy costs, and helps your dryer last longer.
