Nine months of heating pushes a lot of air through your ducts
Your furnace runs October through June here. That is nine months of air moving through the same ducts, picking up dust and whatever else settles in them along the way. Every time the furnace kicks on, that air moves through the house again.
Winter nights here average 35°F from December through February, so the furnace is cycling on and off most nights for a good stretch of the year. Each cycle pushes more air, and more of whatever is sitting in the ducts, through the house.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home, so the honest answer depends on what a contractor finds when they look inside. Homes here run their heating and cooling nine months out of the year, October through June, so dust has more time to build up with less of a break than places with a short winter. If you can see dust kicking out of the vents when the system starts, or nobody has looked inside the ducts in years, that is reason enough to have them checked.
- Is air duct cleaning worth it?
- It is worth it when the ducts are actually dirty, not just because time has passed. Clean ducts mean the air moving through your house on cold nights and warm days isn't carrying dust and debris with it. A contractor can open a few vents and show you what is inside before you spend anything, which tells you more than any general rule would.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork, then uses brushes or air tools to loosen dust and debris inside the supply and return ducts as it gets pulled out. Every vent cover in the house comes off to get cleaned. The furnace or air handler and its coil usually get checked too, since debris collects there before it ever reaches the ducts. Once that is done, the covers go back on and the system runs as it did before, moving cleaner air through the house.
