How often should you clean your dryer vent?
Short answer: about once a year — more often if your vent run is long, exits through the roof, or your household runs the dryer daily. Here's why it matters more than most people think.

Lint is extremely flammable, and failure to clean the vent is the leading cause of dryer fires. A clogged vent traps both heat and fuel in the same line.
Dryer fires in the US: the real numbers
This isn't a scare tactic — it's what US fire departments actually respond to. According to the National Fire Protection Association (NFPA), American fire departments answered an average of 13,820 home fires involving clothes dryers every year (2014–2018 data). Those fires caused an average of 7 deaths, 344 injuries, and $233 million in property damage annually.

The US Fire Administration adds two details worth knowing: "failure to clean" is the leading factor in a third of dryer fires, and dryer fires peak in January — when cold, dry Colorado air has everyone running more laundry. Lint, dust and fiber are the items most likely to ignite first, which is exactly what builds up inside a vent line you can't see.

The signs most homeowners miss
The biggest warning sign is a dryer that suddenly needs two cycles for the same load. Others: the laundry room feels hot or humid, there's a burning or musty smell while the dryer runs, or the top of the dryer is hot to the touch. Any one of these means airflow is restricted somewhere in the line.
In Colorado homes, long vent runs in two-story builds and roof exits clog faster than the short through-the-wall vents many guides assume. If your vent exits through the roof, plan on cleaning it every 6 to 9 months.
It costs you money before it burns
A restricted vent makes the dryer run longer and hotter to do the same work. After a proper cleaning, most homeowners go back to a single cycle per load — that's the fire risk gone and a real dent in the energy bill.

Dryer vent questions, answered
How often should I clean my dryer vent?
Once a year for most households. If you do laundry daily, have a long vent run, or the vent exits through the roof or a second floor — common in Colorado two-story homes — every 6 to 9 months is safer.
What are the warning signs of a clogged dryer vent?
Clothes needing more than one cycle to dry, the laundry room feeling hot or humid during a load, a burning or musty smell while the dryer runs, or the outside of the dryer feeling unusually hot.
Can a clogged dryer vent really start a fire?
Yes. Lint is extremely flammable, and thousands of U.S. house fires every year start in dryers — failure to clean the vent is the leading cause. Clearing the vent removes both the fuel and the heat trap.
How common are dryer fires in the US?
According to the NFPA, U.S. fire departments respond to an average of 13,820 home fires involving clothes dryers each year, causing about 7 deaths, 344 injuries, and $233 million in property damage annually. Failure to clean the dryer is the leading factor in a third of these fires, and they peak in January.
Can't I just clean the lint trap?
The lint trap catches most lint, but not all of it. Fine particles get past the screen on every load and build up inside the vent line over months and years — that's the part you can't reach without proper brushes and vacuum equipment.
Will a clean vent lower my energy bill?
Usually, yes. When airflow is restricted, the dryer runs longer and hotter to do the same job. Most homeowners see drying times drop back to a single cycle after cleaning.
Do you clean the whole vent line or just the ends?
The full run, from the back of the dryer to the exterior hood. The line is brushed and vacuumed end to end, and the exterior hood and damper are checked to make sure air is actually flowing out.
