Seven months of heating pushes air through your ducts
Your furnace runs October through April here, seven months out of the year. Every one of those months it is pulling air through the same ductwork, and whatever is riding in that air, dust, pet hair, the fine grit that comes in under doors, settles inside as it moves.
Most homes in Madison County are single-family houses people own rather than rent, so the ducts in them are the same ones year after year, not swapped out between tenants. With winter nights averaging 25°F, the system is working hard and often to keep up, and dirty ducts make it push harder to move the same air through your house.

- How often should air ducts be cleaned?
- There's no fixed number of years that fits every home. A contractor can look inside your ducts and tell you whether there's enough buildup to matter. If anyone in the house has allergies, or you've had renovation work that left dust behind, it's worth having them checked sooner rather than waiting.
- Is air duct cleaning worth it?
- It depends on what's going on in your ducts right now. If you can see dust building up around your vents, or it's been years since anyone looked inside them, cleaning them makes sense. It won't fix a heating or cooling problem on its own, but it does clear out what's blocking airflow so the rest of the system can do its job.
- What does air duct cleaning involve?
- A contractor uses tools to loosen dust and debris from inside the ductwork, then vacuums it out with a system that pulls everything to the outside instead of pushing it further into your home. They'll also check the vents and the return air ducts, since dust settles wherever air moves slowly. Most jobs cover the whole duct system, not just the parts you can see.
