A blocked dryer vent is one of the most common fire risks in an American home, and one of the easiest to eliminate. Ace Chimney Service cleans dryer vents throughout Crystal Lake and McHenry County, seven days a week.
Why lint is a genuine hazard
Dryer lint is fine, dry, and highly combustible. The lint screen catches some of it; the rest travels into the vent duct, where it settles and compacts, particularly at bends and along horizontal runs.
As the duct narrows, airflow drops. The dryer’s moist exhaust cannot escape properly, so cycles get longer, the appliance runs hotter, and heat builds up in exactly the place where combustible lint has accumulated. Failure to clean dryer vents is the leading cause of home clothes dryer fires — not a defect in the appliance, but an accumulation nobody could see.
Signs your vent needs attention
- Loads needing more than one cycle to dry
- Clothes coming out hot and still damp
- The dryer body or the laundry room noticeably hot during a cycle
- A burning or scorched smell
- Lint collecting around the door seal or filling the screen unusually fast
- Little or no air movement at the outside vent hood
- The vent flap not opening when the dryer runs
How we clean it
We disconnect the dryer and work the full length of the duct with rotary brushes on flexible rods, driven from the appliance end and, where access allows, from the exterior hood as well. A vacuum captures the debris as it is dislodged, so the lint ends up in our equipment rather than across your laundry room.
The exterior hood gets cleaned and the damper checked — flaps stuck shut by lint or paint are a frequent and easily missed cause of poor airflow. We then reconnect the dryer, confirm airflow at the hood, and run it to verify the improvement.
We also look at the duct itself. If it is ribbed foil or plastic accordion hose, we will say so, because those materials trap lint and are not what should be used. Rigid or semi-rigid metal is the appropriate material.
Why a chimney company does this work
It is the same discipline. A dryer vent and a chimney flue are both exhaust systems that fail when a combustible deposit restricts airflow, and both are cleaned with rotary equipment and verified by checking that the exhaust actually reaches the outside. The tools and the thinking are shared, which is why sweeps have cleaned dryer vents for as long as the appliance has existed.
If we are already at the property for a chimney sweep, adding the dryer vent to the same visit saves a second trip. Whole-home ductwork is a separate service — see air duct cleaning.

Frequently Asked Questions
How often should a dryer vent be cleaned?
Once a year for most households. Larger families, homes with long or complicated vent runs, and anyone drying bedding or towels heavily should consider every six months.
What are the warning signs?
Clothes taking two cycles to dry, the dryer or the laundry room getting unusually hot, a burning smell, the lint screen filling faster than normal, and no visible airflow at the outside vent hood.
Is a clogged dryer vent really a fire risk?
Yes. Lint is highly combustible, and failure to clean is the leading cause of home clothes dryer fires. It is one of the most preventable fire risks in a house.
Can I just clean it myself with a brush kit?
You can clear the first few feet. Most vent runs turn, rise, or travel a considerable distance through a wall or ceiling, and the compacted lint that matters usually sits well beyond a consumer kit’s reach.
Does a longer vent run need cleaning more often?
Yes. Every foot and every elbow slows airflow and gives lint somewhere to settle. Long runs and multiple bends clog considerably faster than a short straight one.
Will cleaning the vent reduce my energy bill?
Usually it will. A restricted vent forces the dryer to run far longer to dry the same load, and long cycles are what drive the running cost up.
Should I use flexible foil or plastic duct?
Neither. Ribbed foil and plastic accordion duct trap lint and can be a fire hazard. Rigid or semi-rigid metal duct is what should be used, and we will tell you if yours needs replacing.
Do you clean vents in condos and townhomes?
Yes. These often have long shared or vertical runs that clog badly and are essentially impossible to reach without proper rotary equipment.
