DuctMedic nationally certifies its technicians with 10 months of intensive training before releasing them into the world to cleanse dingy ducts and extract lint from clogged dryer conduits. Over time, un-purged vents gradually fill with flammable lint, which restricts airflow and can cause the machine's motor to overheat, a common cause of household fires and the destruction of countless love notes from the washing machine. DuctMedic's experienced fluff-mining crew draws out the dangerous buildup during a two-hour dryer-duct cleaning enhanced with video-assisted equipment to guarantee every stray cotton ball is extracted. With unobstructed ventilation, machines will run more efficiently and reduce levels of dust, pollutants, and humidity in household air. Annual or semi-annual vent excavations can also help to preserve clothing by directing heated breezes and the vengeful ghosts of missing socks away from delicate fabrics.
