Cherry Hill - According to the U.S. Consumer Product Safety Commission, more than 15,000 fires are sparked every year by clothes dryers. Lint and other debris can build up in your dryer vent, reducing air flow to the dryer, backing up dryer exhaust gases, creating a fire hazard.Jamie Schmidt , a dryer vent technician at GreenWay Pressure Washing in Cherry Hill NJ, said the first sign that you might have a clog is when your Clothes take longer to dry. "The dryer is designed to exhaust the heat and the moisture while it's drying. If that heat can't escape fast enough through the vent it causes dryer to work harder. that means the dryer works harder and heat builds up and that is what can lead to a dryer vent fire." Schmidt said it's a bigger problem in new homes, where the dryer is placed far away from the vent outside the home." Another issue we see is animals making nest inside the dryer vents, This happens more in the Winter Months." Schmidt say's dryer vents should be Inspected and cleaned Annually. " You should have cleaning done Annually to be certain vent is working properly and efficient."
