What Slidell's storms leave behind in your ducts
St. Tammany Parish sees damaging wind often, 88 events over the last ten years. Each one is a chance for moisture and outside air to work into your ductwork, through a cracked seam, a loose vent, or a system that lost power and sat shut down. Almost half of Louisiana households went at least a day without power in 2024, and a duct system that sits idle that long collects dust and lets humidity settle into it.
Your furnace only runs November through March here. The rest of the year, your ducts are carrying cooled air, and any dust or debris already inside gets pushed through the house every time the system runs.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. If your home had water damage, storm damage to the roof or attic, or you notice dust blowing out of the vents when the air kicks on, that's reason enough to have them cleaned. Slidell gets its share of damaging wind each year, and a roof leak or storm opening into the attic is one of the faster ways ducts get dirty between cleanings.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason behind it, not on a set schedule just to have it done. Dust buildup, a musty smell when the air runs, or visible debris coming from the vents are signs the ducts are the problem rather than the filter. If nobody in the house has allergy or breathing issues and you don't see or smell anything off, cleaning on a fixed timeline usually isn't necessary.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris from the inside of the duct walls, then pulls it out through the vacuum. The supply and return vents get cleaned along with the ducts themselves, and the register covers usually come off for a proper wipe down. On some jobs the coil and blower housing get inspected too, since dust in the ducts often means dust has reached those parts as well.
