Lint build-up can cause reduced airflow, which in turn causes overheating. When this happens the high temperature limit safety switch cycles on and off.
Most switches weren't designed to cycle on and off continuously which can cause them to fail.
The Consumer Products Safety Commission estimates that there are an estimated annual 15,500 fires, 10 deaths and 310 injuries associated with clothes dryers. This also produces over $84,000,000 in property damage.
Accumulation of lint and reduced exhaust airflow provide conditions ripe for a fire. Lint is highly combustible. Lint is also one of the main ingredients in a recipe for home-made fire starters.
LOWER ENERGY BILLS
Proper airflow can decrease drying time, thus decreasing operating costs. It helps the dryer to operate efficiently, which can extend the life of the dryer.
An extra bonus is that clothes will dry at lower temperatures and in less time. Which will help prevent unnecessary wear and tear on clothing and also extend their life.
WHO NEEDS THIS SERVICE?
Almost Everyone with a dryer!
Especially those homes with dryers located on inside walls, or those located on second floor laundry rooms. These centralized locations cause dryers to be vented greater distances, up to or over 50 feet. This can result in lint buildup and other obstructions which can seriously affect the performance of dryers.
Most of the dryer manufacturers recommend annually delinting of the dryer vents, for the dryer to work at its maximum efficiency.
If you have an older home you may have a duct system that is possibly more restrictive than today's standards. If so, it's even more important to have your dryer vents cleaned regularly.
CHARACTERISTICS OF AN INEFFICIENT DRYER
1) It takes more than one cycle to dry your clothes.
2) The dryer vent hood flapper doesn't open.
3) The clothes that come out of the dryer are hotter than normal.
