What Jacksonville's storms push into your ducts

Onslow County sees 68 damaging wind events over ten years, and wind that strong drives dust and debris into any gap in your ductwork. Add in five months of heating season from November through March, and that debris gets pushed through the system and settled into the ducts every time the furnace runs.

Power outages add to the problem. A quarter of North Carolina households lost power for 24 hours or more in 2024. When the system sits off, dust settles in the ducts instead of moving through. When it kicks back on, that buildup blows straight into the rooms of the house.

How often should air ducts be cleaned?
There's no fixed schedule that fits every home. If anyone in the house has allergies, or you've had a pest problem or water damage in the ductwork, it's worth doing sooner rather than later. Ducts that pull air through a musty crawlspace or attic tend to collect more than ducts that run through conditioned space. A contractor can look inside with a camera and tell you what's actually built up in there.
Is air duct cleaning worth it?
It depends on what's actually in your ducts. If you can see dust building up around the vents, or a room fills with dusty air when the furnace kicks on, cleaning will make a real difference. If the ducts are newer or the house has stayed dust-free, there's less to gain. A contractor can look inside with a camera and tell you whether there's enough buildup to justify the work.
What does air duct cleaning involve?
A contractor connects a vacuum to the duct system to pull it under negative pressure, then works through each vent with brushes or air whips to knock loose dust and debris so it gets pulled out rather than pushed further into the ducts. The furnace or air handler gets cleaned too, since the coil and blower collect the same dust. Vent covers usually come off for a proper cleaning, and the whole system gets sealed back up when the work is done.
