What five months of heat does to the ducts
Orangeburg County homes run the furnace November through March, with winter nights averaging 37°F through the coldest stretch. That is five months of the blower cycling warm air through the same ductwork, night after night, pulling household dust along with it and packing it into the bends and the coil.
Power does not always stay on through that stretch. The county has logged 177 damaging wind events over the last ten years, and in 2024 nearly half of South Carolina households lost power for 24 hours or more. Every time the blower stops and restarts, it pulls against whatever has settled in the ducts since the last run.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. Homes with pets, a smoker, or someone with allergies tend to need it sooner than others. Recent construction or renovation work is another reason to have them checked, since drywall dust settles deep into the ductwork. Outside of that, watch for dust blowing out of the vents when the system runs, or a musty smell when the heat kicks on.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason behind it, not as routine upkeep on its own. Dust blowing out of the vents, a musty or moldy smell, or signs of rodents or pests in the ductwork are all good reasons to get it done. If the ducts look clean and the air coming out doesn't smell or carry dust, cleaning them won't make much difference to your air quality or how the system runs. A contractor can look at the ducts and tell you honestly whether it's needed.
- What does air duct cleaning involve?
- A contractor uses brushes and a vacuum system to loosen and pull dust and debris out of the ductwork, working through the supply and return runs. Each vent cover gets removed and cleaned, and the coil and blower near the furnace or air handler are often cleaned at the same time since dust collects there too. The goal is to clear out what's built up on the inside walls of the ducts, not just what's near the vent openings.
