Seven months of heat means seven months pulling air through those ducts

Your furnace runs October through April here, close to seven months a year. Every one of those months it is pulling air through the same ducts, and the dust and pet hair that ride along with it settle inside a little more each time. Most homes in Wood County are single-family and owner-occupied, so it is one household's dust building up in the same duct run year after year, not several units sharing and thinning it out.

When the furnace shuts off between cycles, some of what is sitting in the ducts settles into the runs closest to the vents. On a night that drops to 25°F, the burner is lighting and the blower is pushing air through those same ducts many times before morning.

How often should air ducts be cleaned?
There's no fixed schedule that fits every home. Most homes don't need it unless there's a reason, like visible dust at the vents, a musty smell when the furnace runs, or recent renovation work that stirred up debris behind the walls. Homes here run the furnace October through April, so if the ducts are due, it's worth having them checked before the cold nights start. A contractor can look inside and tell you if cleaning makes sense now or can wait.
Is air duct cleaning worth it?
It depends on what's actually in your ducts. If there's visible dust coming out of the vents, a musty smell when the furnace runs, or debris left over from past renovation work, cleaning them makes a real difference to the air moving through the house. If none of that applies, it's not something you need to do on a schedule just to do it. A contractor can inspect the ducts and tell you honestly whether cleaning will help.
What does air duct cleaning involve?
A contractor uses brushes and a high-powered vacuum to loosen and pull dust and debris out of the ductwork. Each supply and return vent gets cleaned along with the main trunk lines. The furnace and coil often get looked at too, since they connect straight to the same air path. The whole job is done through the existing vents, so nothing in the walls or ceiling needs to be opened up.
