WHEN LINT CLOGS A DRYER DUCT:
We remove lint, bird nests and articles of clothing from dryer ducts in homes, beauty salons, apartments, condos and laundromats. Safety King air duct cleaning company uses specialized high-powered compressed air nozzles, custom brushes, and vacuum equipment to clean your dryer ducts. We clean the entire duct length from the transition duct (where the duct hooks to the dryer) to the exit/termination. Some cleanings can be done from the exterior only, but many require that we access the transition duct and the dryer itself inside of your home/building. Safety King does not clean inside the dryer or provide appliance service/repairs.
DRYER DUCT CLEANING:
Certified Dryer Exhaust Technicians (C-DET) On Staff
The information below is provided as a courtesy. Our source for this data is the Chimney Safety Institute of America and the standards currently published as the International Mechanical Code (IMC). Please consult the Owner’s Manual of your clothes dryer for additional information and for cautions that may be specific to your region or to your appliance.
Dryer exhaust systems should be independent of all other venting systems. Clothes dryer exhaust must not be connected to a gas vent connector, a gas vent or a chimney. Clothes dryers should only be connected to ductwork designed specifically for exhausting that particular appliance.
Most clothes dryers actually have two separate ducts or duct systems. One is called the connector or transition duct. This is the short (8’ or less in length) duct that normally connects the exhaust vent of the dryer to an opening in a nearby wall. This wall opening is the entry point for the second duct or duct system, called the main duct, which is often concealed inside walls, ceiling or attic spaces, and must lead always and only to outside air.
The connector duct must be secured to the dryer and to the wall opening using heat-resistant metal tape, never with screws, rivets or any fasteners that protrude into the interior of the duct. Protrusions into the duct cause turbulence in the airflow and collect lint, reducing the efficiency of the duct system. The main dryer duct, at the point at which it connects to outside air, must have an exhaust hood with a self-closing damper to prevent backdraft and entry of small animals.
Both the connector duct and the main duct must be a minimum of 4” in diameter. A one-half-inch buildup of lint in a 4” diameter duct reduces its efficiency by 44%. The length of the connector duct must not exceed eight feet. The length of the main duct must not exceed 25 feet (note: for each forty-five degree bend, add 2 ½ feet to the total duct length, and for each ninety-degree bend, add 5 feet to the total duct length).
Both connector and main ducts must be metal (either rigid or flexible) and be thick enough, minimum 28 gauge, to be non-combustible. Metal foil does not qualify and can be easily ignited. Plastic, of course, is a distinct fire hazard and must never be used in either duct.
Consider installing preventive technology to avoid excessive lint accumulation in your dryer exhaust duct that can lead to a dryer fire. Safety King offers the LintAlert Dryer Safety Alarm. Click the image below to view a video or ask your Safety King technician for details. The Lint Alert is an easy-to-install safety device that uses sophisticated differential technology to monitor your dryer's exhaust duct system. When the pressure inside your dryer exhaust duct reaches unsafe levels (usually because excessive lint buildup inside the duct restricts the air flow), the Lint Alarm will activate it's alarm and warn you that maintenance is required.
