This is the most common and easily identifiable symptom for homeowners. If a single load of laundry requires multiple cycles to dry completely, it's a primary indicator that restricted airflow from a clogged vent is trapping moist air in the drum.

What the Pros Say
"The number one thing customers tell me is, 'My clothes just aren't drying anymore.' That's the classic sign. When I show them the amount of lint I pull out—sometimes a full bucket's worth—they finally understand the fire hazard they were living with."

Mike Johnson
Dryer Vent Technician, 15 years"We see so many service calls for 'broken' dryers that are actually just severely clogged vents. Before you spend hundreds on a repair, spend a little on a cleaning. It solves the problem nine times out of ten and saves you money in the long run."

Sarah Chen
Appliance Service Manager"It's not just about lint. The heat and moisture create a perfect environment for mold. Furthermore, a clogged vent causes the dryer's high-limit thermostat to trip constantly, leading to premature failure of expensive electronic components."

Carlos Rodriguez
Master HVAC & Appliance Technician"Annual dryer vent cleaning is one of the most cost-effective safety measures a homeowner can take. It's an 'out of sight, out of mind' problem, but the consequences of ignoring it, from high energy bills to house fires, are significant."
