Check your outdoor clothes dryer vents!

Make sure the air exhaust vent pipe is not restricted and the outdoor vent flap will open when the dryer is operating. Once a year, or more often if you notice that it is taking longer than normal for your clothes to dry, clean lint out of the vent pipe or have a dryer lint removal service do it for you. Blockage in dryer exhaust vents can also occur from the nests of birds or other animals.
Clothes dryers should be vented directly to the outside. Serious hazards occur when dryer vents do not exhaust directly to the outside. CLEAR AWAY THE SNOW!
