What Florence County storms push into your ducts

Florence County has logged 97 damaging wind events over the past ten years. Wind at that scale carries dust and debris toward the house, and what gets past a door or window is pulled into the return vent and settles in the ductwork over time.

The county has also seen 45% of South Carolina households lose power for at least a day in 2024. When power drops and comes back, the system starts up again and pushes air through ducts that have not been cleaned. Heat only runs November through March here, so the dust that collects over the rest of the year sits in the ducts until the system cycles on again.

How often should air ducts be cleaned?
Most homes do fine with duct cleaning every three to five years. Homes with pets, a recent renovation, or someone with allergies may need it sooner. If a home has had water damage or you can see dust blowing out of the vents, that's a sign to have it looked at sooner rather than on a schedule.
Is air duct cleaning worth it?
It depends on what's going on in the ducts. If there's visible mold, heavy dust buildup, or signs that pests have gotten into the system, cleaning them makes sense. If the ducts look fine and the furnace filter is doing its job, cleaning on a whim usually isn't worth the disruption. A contractor can look at the actual ductwork and tell you whether it needs it.
What does air duct cleaning involve?
A contractor uses specialized vacuum equipment connected to the duct system to pull loose dust, debris, and buildup out of the supply and return lines. Brushes or air whips may be used to knock buildup loose from the duct walls before it's vacuumed out. The vents, grilles, and sometimes the blower compartment get cleaned as part of the job too.
