Signs that your dryer vent needs cleaning include clothes taking longer to dry, the dryer feeling hot to the touch, clothes being unusually hot at the end of a cycle, a burning smell when the dryer is running, or a humid laundry room. To prevent these issues, have your vents cleaned at least once a year, or twice a year if you use your dryer frequently.
