Six months of heating pushes dust through your ducts
Your furnace runs November through April here, six months of the year, on nights that average 35°F. Every time it kicks on, air moves through the ductwork and stirs up whatever has settled since the last cycle. Dust, pet hair, and skin cells build up along the inside of the duct walls over a season of that.
DeKalb County has also logged 132 damaging wind events and three winter storms over the past ten years. Storms like that can drive debris into vents and ductwork, adding to what collects there between cleanings.

- How often should air ducts be cleaned?
- Most homes do fine with a duct cleaning every few years, not on a strict yearly schedule. If anyone in the house has allergies, or you've had rodents, a leak, or a renovation that kicked up dust, it's worth doing sooner. Homes here run the furnace November through April, so whatever settled in the ducts over summer gets pushed through the house once that starts.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason for it, like visible dust coming out of the vents, a musty smell when the system runs, or known mold or pest activity in the ducts. It won't lower your heating or cooling bills, and there's no proof it prevents illness in a typical home. If nothing's wrong that you can see or smell, cleaning on a schedule for its own sake usually isn't necessary.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system to create negative pressure, then uses brushes or air tools to loosen dust and debris along the way so it gets pulled out rather than pushed further into the ducts. The supply and return vents, the main trunk lines, and often the coil and blower compartment get cleaned in the same visit. A contractor can walk through what your specific system needs before starting.
