What the wind leaves behind in your ducts
Hancock County has seen 20 damaging wind events over the past ten years. Storms like that drive dust and debris into a house through every gap they can find, and a duct system pulls it in and holds onto it long after the weather clears.
Power loss makes it worse. Mississippi saw 30% of households go at least 24 hours without power in 2024, and a system that sits idle during a storm isn't moving air to keep anything from settling in the runs. Then the furnace kicks back on for the five months of winter here, and it pushes that settled dust through the house instead of clearing it out.

- How often should air ducts be cleaned?
- Most homes do fine with duct cleaning every few years, not every year. If anyone in the house has allergies, or you have had a lot of dust or renovation work, sooner makes sense. Homes here that have had storm damage or lost roof or window seals should also get a look, since wind and debris can push dirt and moisture into the ductwork.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason for it, like dust coming out of the vents, a musty smell, or work done on the roof or attic that could have let debris into the ducts. It is not something that needs to happen on a fixed schedule for most homes. A contractor can look at the ducts and tell you whether there is buildup worth removing.
- What does air duct cleaning involve?
- A contractor opens access points along the ductwork and uses a vacuum system to pull out dust, debris and anything else that has settled inside. The vents and registers get cleaned along with the supply and return lines. Some contractors also check the coil and blower while they are in there, since dirt in the ducts often means dirt in those spots too.
