Lint and other debris can build up in your dryer hose and vent duct. The debris causes reduced air flow that traps exhaust gases. If the dryer hose and vent duct are not cleaned and inspected every year, this could create a fire.
Be sure to clean the lint screen between loads of laundry. However, cleaning the screen alone does not stop the vents from becoming clogged. Your dryer will work better and more efficiently if the ducts are clean. Dyer maintenance may also help save energy and eliminate mold issues.
There are several companies in Orlando that provide this type of cleaning service.
