Thanks for connecting us to the free vent check kit link! One of the guys my significant other worked with lost his home to a dryer fire and it was devastating. They lost everything, including all his tools and equipment for his second job. The truly devastating part of it, though, was trying to get the insurance company to get off the pot and do something for them. Glad to learn there's a kit that can help let you know if you need additional cleaning, other than what you can see yourself in the lint trap.
