Many people blame their dryer's inefficiency on the actual dryer, but most of the time it is their dryer exhaust vent that is causing the problem. Even with proper lint trap maintenance, a lot of lint and debris is routinely expelled through the exhaust vent. Over time, buildup occurs, restricting airflow. Dirty or clogged vents don't allow the hot air and moisture to escape efficiently, causing it to take longer to dry a load of laundry. This not only wastes your time, it also causes unnecessary wear and tear on your appliance.
