Fires in dryer ducts pose a serious risk to you
In fact, the Consumer Product Safety Commission (CPSC) has issued a consumer product safety
alert. According to the CPSC, annually there
are 15,500 fires, 10 deaths and 310 injuries due to dryer exhaust duct
fires. These fires result in millions of dollars in property loss.
Because the dryer duct is usually 4" diameter, the slightest amount of
deposit can greatly reduce the ability to exhaust. When it starts taking longer to dry the clothes, the problem is not usually the dryer but
rather the exhaust system.
You could be paying double

Dryer duct cleaning will substantially lower
your power bill. Every 45 min. cycle can cost as much as $1. Can you
afford to pay double? If your dryer is getting hot but still taking forever, it's almost always your dryer vent.
