Warning signs your Salem home needs dryer vent cleaning include clothes taking longer than one cycle to dry, dryer exterior feeling excessively hot during operation, burning smell when dryer runs, visible lint around exterior vent opening, clothes hotter than normal at cycle end, and increased utility bills from extended drying times. According to the National Fire Protection Association, these symptoms indicate dangerous lint buildup creating fire hazards requiring immediate professional attention. Salem’s humid Pacific Northwest climate can cause lint to mat and compact inside vents, accelerating blockage compared to drier climates. Ignoring warning signs risks dryer fires, carbon monoxide buildup with gas dryers, premature appliance failure, and wasted energy.
