General Questions

Can I service the dryer exhaust myself or do I need to hire a professional?

This depends on the length of the dryer run, available access to both ends of the exhaust conduit, and general ability of the cleaner. Typically, a clogged or blocked condition can be lessened with what you can reach by hand, blown out with a leaf blower or vacuumed with a shopvac. Several DIY dryer vent cleaning systems are available from your local hardware store or online. Always allow the dryer to cool down after running for extended periods before attempting any self-servicing. Professional duct cleaning services will use a combination of vacuums and flexible rods with brushes to effectively bring the duct back to its new original state and can cost as little as $80. If the dryer exhaust vent is clogged or blocked, do not run the dryer until the exhaust conduit has been serviced as this may cause a fire. More information: Professional Cleaning.

Where can I buy a LintAlert and are they available online?

The LintAlert is currently for sale online and at many retailers.  Most of the retail outlets, catalogs and online stores that carry the LintAlert are posted on our “Buy” page

How does the LintAlert work and what does it do?

The LintAlert monitors and displays the back pressure levels found in the exhaust conduit of the dryer. Pressure levels found in the duct work between the back of the dryer and the exterior vent hood typically increase over time due to lint build-up or other restrictions like birds nest or vent hoods that become inoperable. The LintAlert features an innovative and responsive digital high flow-impedance air differential pressure thermal-anemometer-based sensor. Coupled with a programmable integrated microprocessor, the device can determine if your dryer is operating, and what levels of pressure exist. When the pressure reaches an unsafe level, the alarm state will activate, indicating maintenance is required. Prior to the alarm state, a slow progression of the LED Blockage Indicator will display fractional build-up.

Do I need a LintAlert if I vent straight out through the wall?

Yes. Lint can still build-up in the flex hose, due to kinking. The transition hose itself can get crushed. The vent hood may become blocked or inoperable.

Typically, how often should the dryer duct be cleaned out?

Typically, every 18-24 months. However, variables including the frequency of running the dryer, the total effective length of duct and the type of termination or vent hood may require shorter intervals.

What else can create blockage in the ductwork besides lint build-up?

Bird and rodent nests in the duct or vent hood are common. Roof vents may incorporate a screen or grill that can quickly accumulate lint, blocking the opening. Long duct runs or excessive elbows cause poor airflow and can accelerate lint build-up. Condensation within the duct, caused by the duct running through a unconditioned attic or crawlspace, can also accelerate build-up. Most common are crushed flex hoses from dryers too close to the wall.

What is the term of the warranty for the LintAlert
