How long does a dryer vent cleaning take?
A standard residential dryer vent cleaning visit takes between 45 and 90 minutes. The time varies based on duct length, number of bends, the amount of lint accumulation, and whether the exterior vent cap requires attention. Complex installations with long runs or difficult access may take longer.
Do I need to be home during the cleaning?
For most residential cleanings, yes — the technician needs access to both the dryer connection area and, in some cases, the exterior vent cap. If the exterior cap is accessible without entering the home, some arrangements can be made, but typically having someone home ensures all aspects of the service can be completed.
Will the technician move my dryer?
In most cases, the dryer needs to be pulled away from the wall to access the duct connection. A professional technician will move the dryer as needed and return it to position after service. Letting the technician know in advance if the dryer is a stacked unit or in a tight space helps with scheduling.
How do I know if my dryer vent needs cleaning?
The most reliable performance indicator is extended drying time — if loads that previously dried in one cycle now take two or more, the vent is likely restricted. Other signs include the dryer feeling hot to the touch on the outside, a burning or musty smell, the exterior vent flap not opening during operation, and visible lint around the dryer connection area.
Can a dirty dryer vent cause a fire?
Yes. Lint is highly flammable, and when it accumulates in a dryer vent duct, it creates a concentrated fuel source in close proximity to heat. The U.S. Fire Administration consistently identifies failure to clean dryer vents as a leading cause of residential dryer fires. Annual professional cleaning is the primary preventive measure.
What is airflow testing?
Airflow testing uses a calibrated meter to measure the volume of air moving through the vent duct in cubic feet per minute (CFM). Measuring before and after cleaning provides objective documentation that the cleaning was effective. Airflow testing is a standard part of a professional service visit.
