| How often do vents need cleaning?
The better a dryer vent blows, the less lint builds up in it. Short vents blow
better than long ones. Full size dryers blow better than smaller stack dryers or
older dryers. Vents with a lot of turns and elbows blow worse and build up more
lint. Very short vents attached to full size dryers may never need cleaning!
Most vents, however, need cleaning every two to three years, depending on
the factors above.
| Are dirty vents a fire hazard?
A plugged vent will certainly cause a dryer to run hotter and increase the
chance that something could catch fire. A dirty vent, however, is only one link in
a chain of events that must occur for a fire to start. Other events may include:
failure of thermostat and limit switches in the dryer, lint inside the dryer, a
missing or damaged lint screen, and a crushed hose behind the dryer. Some of
our competitors employ "scare tactics" and reprint newspaper articles about
fires caused by dryers. Though fire hazards may be exaggerated, many fire
departments and insurance companies do require that dryer vents be inspected
and cleaned regularly.
