Dryer Vent Cleaning & Blockage Removal - San Francisco

## Complete Blockage Required Emergency Cleaning Our team responded to a San Francisco residence where the homeowner reported extended drying times and poor dryer performance. Upon inspection, we discovered the dryer exhaust duct was completely blocked with accumulated lint, creating a serious fire hazard and preventing proper ventilation. The blockage was so severe that airflow was virtually eliminated, forcing the dryer to work under dangerous conditions. ## Professional Cleaning and System Restoration Using specialized rotary brush equipment and high-powered vacuum systems, we thoroughly cleaned the entire exhaust pathway from the dryer connection to the exterior termination. The cleaning process removed substantial lint accumulation that had built up over multiple years of use. We also cleaned the dryer's internal lint pathways and replaced the transition duct to ensure optimal performance. ## Code Compliance and Safety Verification Following the cleaning, we verified that the exhaust system meets IRC M1502 requirements, including proper termination location and backdraft damper function. The system now provides unrestricted airflow to the outdoors, significantly reducing fire risk and improving dryer efficiency. We recommend annual professional cleaning to prevent similar blockages and maintain safe operation. ## Results: Restored Safety and Performance Post-service testing confirmed full airflow restoration and proper system operation. The homeowner will now experience normal drying times, reduced energy costs, and most importantly, eliminated fire hazards associated with blocked dryer vents. This case demonstrates the critical importance of regular dryer vent maintenance for San Francisco homes.
