Easier the ability is for air to flow through air ducts, easier air is delivered through the system to living spaces. If air ducts have any type of major blockage creating a hampering of air flow there will be higher energy costs noticed after a period of time.

Bi-products from these materials will likely circulate in the air of the home of where they are found. This is also a sign that most likely, there are rodents living in the air ducts or insects have nested.
