Seven months of heating a year gives ductwork little rest
Your ducts move air through the house from October through April, seven months out of the year. Every time the furnace kicks on, that same air passes through the same runs of duct, and whatever dust settles in there gets stirred and pushed into the rooms you live in.
Power does not always stay on to keep that air moving the way it should. Greenville County has logged 122 damaging wind events over the past ten years, and in 2024 close to half of South Carolina households lost power for at least a full day. When the power drops, the blower stops, and the dust already sitting in the ducts just stays put until the system starts back up.

- How often should air ducts be cleaned?
- Most homes do fine having their ducts checked every few years, with the actual cleaning done when there's a reason for it. If anyone in the house has allergies, or you've had a repair that left dust behind, sooner makes sense. Homes here run the heat from October through April, so ducts that need attention tend to show it once that stretch starts, with musty air or dust coming out of the vents.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason for it, like visible dust at the vents, a musty smell when the air kicks on, or work done on the system that left debris in the ducts. It won't fix a system that's just old or noisy. A contractor can look at your ducts and tell you whether cleaning will actually help or whether the problem is something else.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system and uses brushes or air tools to knock dust and debris loose, then pulls it out before it resettles. The supply and return vents get cleaned along with the ducts themselves. On a forced-air system, the furnace or air handler often gets a look too, since dust builds up there as well.
