Wind and power outages both take a toll on your ducts

Harrison County has seen 53 damaging wind events over the past ten years. Wind like that can loosen duct joints and seams, and once a joint opens, outside dust and debris get pulled in and your blower spreads it through every room the ducts feed.

Power loss adds to the problem. Nearly a third of Mississippi households went at least 24 hours without power in 2024, and every time the system sits off and starts back up, more of that debris moves through the same loose joints.

How often should air ducts be cleaned?
Most homes do fine having their air ducts cleaned every few years. Homes with pets, a smoker, or someone with allergies usually need it more often. If you see dust building up around the vent covers or notice a musty smell when the air kicks on, that's a sign to get them looked at sooner rather than wait.
Is air duct cleaning worth it?
It's worth it if your ducts are actually dirty, and not worth much if they're not. A contractor can look inside with a camera and tell you whether there's real buildup or whether the ducts are in decent shape already. That's a better way to decide than cleaning on a fixed schedule.
What does air duct cleaning involve?
A contractor connects a vacuum system to your ductwork, then uses brushes or air whips to knock loose dust and debris from the inside of the duct walls before pulling it out through the vacuum. Every supply and return vent gets cleaned, along with the grilles themselves. On most jobs the furnace or air handler gets a look too, since the blower and coil sit right in the path of that same airflow.
