Nine months of heating pushes a lot of dust through your ducts
Your furnace runs from September through May here, nine months where air is moving through the ductwork almost every day. Every pass carries dust, pet hair, and whatever else is in the house into the trunk lines and back out through the registers.
Winter nights average 11°F in Franklin County, so the system runs hard and often to keep the house warm, and that means more air moving through the ducts than in a milder place. Over years, that buildup narrows the airflow and can leave dust settling on furniture and floors even after cleaning.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. If anyone in the house has allergies, if you have had a remodel or a new furnace put in, or if you have pets or a smoker in the house, cleaning sooner makes sense. If you see dust coming out of the vents or building up fast on furniture, that is a sign to have it looked at. A contractor can check the ducts and tell you honestly whether it is time.
- Is air duct cleaning worth it?
- It depends on what is going on in your ducts right now. If you can see dust buildup at the vents, if someone in the house has unexplained allergy symptoms, or if you just had construction or a pest problem, cleaning is worth doing. If your ducts look fine and no one is having breathing issues, it is not something you need to do just because time has passed. A contractor can look at your ducts and tell you honestly whether cleaning will help your situation.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or compressed air tools to knock loose dust and debris from the inside of the duct walls, then pulls it out through the vacuum. This covers the supply and return ducts, the grilles and registers, and usually the coils and blower housing on the furnace or air handler. The whole system gets cleaned together, since dust left in one section will just move to another.
