Seven months of heating pushes a lot of air through those ducts
Your furnace runs October through April here, and on nights averaging 25°F it cycles on and off for hours at a stretch. Every one of those cycles pushes air through the same ductwork, and whatever is sitting in the ducts moves with it. Dust, pet hair, and anything that settled over the summer gets stirred up and carried into the rooms you're heating.
Most homes in Jefferson County are single-family houses people own rather than rent, which means whatever builds up in the ducts this winter is still there next winter unless something is done about it. Dirty ducts do not just move dust around. They can leave the furnace working harder to push air through a restricted system, and that shows up as uneven heat from room to room.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, but a good rule is to have them checked every few years and cleaned when they need it. Get it looked at sooner if anyone in the house has allergies, if you've had construction work done, or if you moved in and don't know the ducts' history. Homes here run the furnace seven months of the year, October through April, and that long stretch pushes more dust through the system than a shorter heating season would.
- Is air duct cleaning worth it?
- It depends on what's actually in your ducts. If dust kicks out of the vents when the furnace runs, if a room stays dusty no matter how often you clean it, or if rodents or construction dust got into the system, cleaning solves a real problem. If none of that applies, the benefit is smaller than people expect, since most household dust comes from the room itself, not the ductwork. A contractor can look inside the ducts and tell you whether cleaning will make a difference in your case.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork, then uses brushes or compressed air tools to knock loose dust and debris from the inside of the duct walls so the vacuum can pull it out. Every supply and return vent gets cleaned, along with the main trunk lines. The furnace or air handler often gets a look too, since the blower and coil sit in the airflow path and collect the same buildup.
