Six months of heating pushes the same air through your ducts
Your furnace runs November through April in Sebastian County, six months where the same ductwork moves air through your house day after day. On nights that average 31°F through the coldest months, that furnace is cycling often, and every cycle pushes more dust and debris through the same runs of duct.
Arkansas sees its share of winter storms and wind, and power loss is part of that. About a quarter of households in the state went at least a day without power in 2024. When a furnace sits idle and then starts back up, whatever settled in the ducts during that stretch gets pushed through the house again.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every house. Clean them sooner if someone in the house has allergies, if you have had a rodent or pest problem, or if you just finished a renovation that left drywall dust in the vents. Ducts that stay dry and sealed up can go a long time without needing attention.
- Is air duct cleaning worth it?
- It depends on what is actually sitting in the ducts. If you see dust building up at the vents, or you know there is debris or mold inside, cleaning them is worth it. If the ducts are clean and the system runs fine, cleaning them does nothing for you. A contractor can look inside and tell you which case you are in.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system to create negative pressure, then uses brushes or air tools to knock dust and debris loose so it gets pulled out instead of pushed further in. Every supply and return vent gets cleaned along with the main trunk lines. The furnace or air handler often gets a look too, since dust and debris settle there as well.
