Every clothes dryer duct system is different, but one thing is certain: A clogged dryer duct can increase the amount of time it takes to dry clothing by double or triple the time. What once used to take a thirty minute dry cycle now is taking sometimes up to two hours to dry. Most people don’t quite experience those extreme time differences but in our experience 60-70% of people will notice that after one cycle that their clothes aren’t quite dry yet and will restart the cycle again. Clothing that takes twice as long to dry is not only an energy waster, but also a fire hazard. This also adds much more wear and tear on the machine and cut the life of your dryer in half.
