What Anderson County weather does to your ducts

Your furnace runs November through March here, five months of pulling air through the same ducts that carry cool air the rest of the year. Winter nights average 34 degrees, cold enough that the system cycles on and off often through the night, moving air and whatever is riding in it through the same runs again and again.

Anderson County has logged 111 damaging wind events over the past ten years. Wind like that drives dust and debris into the return side of a duct system, and it settles in the runs where the air barely moves. That buildup sits there until the blower stirs it loose and pushes it out through the vents into the house.

How often should air ducts be cleaned?
There's no fixed schedule that fits every home. Homes with pets, a recent renovation, or someone with allergies usually need it more often than others. If a room stays dusty right after you clean it, or you can see dust blowing out of the vents, that's a sign to get it checked.
Is air duct cleaning worth it?
It's worth it when there's a real reason behind it, not just as something to check off a list. Dust buildup in the ducts can end up back in the air you breathe, and a heavy buildup can make your furnace work harder to push air through. If you can see dust at the vents, notice a musty smell when the system runs, or someone in the house has ongoing allergy trouble, cleaning the ducts is worth doing.
What does air duct cleaning involve?
A contractor connects a vacuum system to your ductwork and uses brushes or air tools to loosen dust and debris along the way, then pulls it out through the vacuum. Every supply and return vent gets checked, and the furnace or air handler compartment usually gets cleaned too since dust collects there as well. The job is finished once the system is put back together and the vents are sealed up again.
