A clogged dryer vent is the most overlooked fire risk in a house. Lint is highly combustible, it collects in the duct where nobody looks, and the dryer keeps pushing hot air into it. Chimney Sweep Bros cleans dryer vents across Orland Park and the Southwest Suburbs — the full duct run, not just the bit you can reach. We are insured, we work seven days a week, and you can call (708) 432-3430.
How to tell your vent is blocked
- Clothes take two cycles to dry. This is the number one sign, and the one everyone ignores or blames on the dryer.
- The dryer or the laundry room is hot to the point of being uncomfortable at the end of a cycle.
- Clothes come out hot and damp rather than hot and dry.
- A burning or musty smell during a cycle.
- The lint trap keeps filling unusually fast, or lint appears around the dryer door seal.
- The outside vent flap does not open or barely moves when the dryer is running — go outside and watch it.
- You have never had it cleaned. If you cannot remember it being done, it needs doing.
Why it matters more than people think
Dryer lint is fine, dry and loosely packed — almost the definition of good tinder. When the duct is restricted, the dryer cannot exhaust properly, the heat has nowhere to go, and the appliance runs hotter and hotter against a duct full of tinder. Clothes-dryer fires are a well-documented cause of home fires in the United States, and failure to clean the vent is the leading factor behind them.
The efficiency argument is the one that usually gets people to act, though: a blocked vent means the dryer runs two or three cycles to do one cycle of work. That is a measurable amount of electricity or gas, every load, for years.
Why the vent still clogs when you empty the lint trap
The lint trap catches some of the lint. The rest goes into the duct, and it accumulates where the airflow slows — at bends, at the transition hose behind the dryer, and at the exterior flap. Long duct runs and multiple elbows make it worse, and so do the crushed flexible foil hoses that are still fitted behind a lot of dryers. Emptying the trap after every load is good practice and it does not clean the duct.
What we do
- Clean the whole run — from the dryer connection, along the full duct, to the exterior termination. Rotary brushes on flexible rods, with a vacuum on the other end.
- Clear the exterior vent and flap, which is where the worst compaction usually is.
- Check the transition hose behind the dryer. Crushed, kinked or foil hoses are a common cause of the problem and we will tell you if yours needs replacing with rigid duct.
- Measure airflow at the exterior vent afterwards so there is evidence the restriction is actually gone.
Most homes need this every year. Large households, pets, or a long duct run mean more often. If your dryer is in the basement with a long run up and out, assume the shorter interval.
Frequently asked questions
How often should a dryer vent be cleaned?
Once a year for a typical household. Sooner if you have a large family, pets, or a long duct run with several bends. The practical test is drying time: if a normal load stopped drying in one cycle, the vent is telling you it needs attention.
Is a clogged dryer vent really a fire risk?
Yes. Lint is dry, fine and highly combustible, and a restricted duct makes the dryer run hotter while it sits packed with that lint. Clothes-dryer fires are a documented cause of house fires in the US, and failure to clean the vent is the leading contributing factor.
I clean the lint trap every load. Isn’t that enough?
No, and this is the most common misunderstanding. The lint trap catches only part of the lint — the rest travels into the duct and settles at bends, at the transition hose, and at the exterior flap. Cleaning the trap is good practice, but it does not clean the duct.
Will cleaning the vent save me money?
It should. A blocked vent forces the dryer to run multiple cycles to dry one load, and every one of those cycles costs electricity or gas. Restoring airflow generally cuts drying back to a single cycle, and it takes strain off the appliance.
Can I clean the dryer vent myself?
You can pull the dryer out and clear the transition hose and the first stretch of duct, and that is worthwhile. What you generally cannot do is clean the full run — particularly a long duct with elbows, or a roof termination — or verify afterwards that the restriction is actually gone. Our DIY guide covers what is safe to tackle yourself.
How long does dryer vent cleaning take?
A typical run takes 45 minutes to an hour. Long ducts, roof terminations, or heavily compacted lint take longer.
My dryer vents through the roof. Is that a problem?
It is harder to keep clear. Vertical runs and roof terminations trap more lint, and the flap is exposed to weather and birds. It does not need replacing, but it does need cleaning on a shorter interval, and it is not a job to attempt from a ladder yourself.
Should my dryer duct be flexible foil or rigid metal?
Rigid or semi-rigid metal duct is the right answer. Flexible foil and plastic hoses crush behind the appliance, kink at the bends, and their ridged interior catches lint. If we find a crushed foil hose behind your dryer we will tell you, because it is often the whole cause of the problem.
