Dryer vent cleaning and home fire prevention
A clogged dryer vent is one of the most overlooked fire risks in a home, and one of the easiest to fix. Here is what the data says, and what to watch for.

Lint is fuel, and a clogged vent is the spark
Every load sheds lint, and not all of it lands in the lint trap. The rest travels into the vent line, where it clings to bends and ridges and slowly builds up. Because lint is extremely flammable, that buildup is the problem.
As the vent narrows, airflow drops. Your dryer has to run hotter and longer to dry the same load, and that heat has nowhere to escape. The National Fire Protection Association reports that failure to clean is the single leading cause of home clothes-dryer fires, behind roughly one in three of them. Those fires cause an estimated $238 million in property damage every year.
The good news: clearing the full vent line removes the fuel and restores airflow. It is one of the cheapest, highest-impact safety steps a homeowner can take.
When to get your dryer vent cleaned
If you notice any of these, it is time. A vent that cannot breathe is both a fire risk and an energy drain.
- Clothes take more than one cycle to dry
- The dryer or laundry room feels unusually hot
- You notice a burning or musty smell when drying
- Lint collects around the outside vent or behind the dryer
- The vent flap outside barely opens during a cycle
- It has been more than a year since your last cleaning
How Fresh Air Vents clears it

How does a dirty dryer vent cause a fire?
Lint is highly flammable. As it builds up in the vent line, it restricts airflow, so heat has nowhere to go. The dryer runs hotter and longer, and that trapped heat can ignite the lint. According to the NFPA, failure to clean is the leading cause of home clothes-dryer fires.
How often should a dryer vent be cleaned?
For most households, once a year. Clean more often if you do frequent loads, have a long or winding vent run, dry pet bedding, or notice any of the warning signs of restricted airflow.
Why is winter worse for dryer lint in Minnesota?
In our long East Metro winters, dryers run more often and cold, dense air outside slows venting, so lint accumulates faster. Late fall is a smart time to have the vent cleared before heavy winter use.
How much does dryer vent cleaning cost?
Dryer vent cleaning is $99 for a ground-level vent or $149 for a roof-access vent, with an optional full-service interior cleaning and inspection for $89. See full details on our pricing page.
