Nine months of heating pushes a lot of air through those ducts
Your furnace runs September through May here, nine months of the year. Every one of those months it pulls air in, warms it, and pushes it back out through the same ductwork. Dust and whatever else is in that air settles along the way, and nine months gives it a lot of time to build up.
Winter nights average 13°F from December through February, so the furnace runs hard and often through the coldest stretch. A duct system working that much all season has less room to move the air your house needs once buildup packs in.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house. If anyone in the house has allergies, or you had work done that left drywall dust or debris behind, it's worth having them looked at sooner rather than later. A contractor can check your ducts and tell you whether they actually need cleaning or can wait.
- Is air duct cleaning worth it?
- It depends on what's actually in your ducts. If dust is visibly blowing out of the vents, or you see buildup when you pull a vent cover off, cleaning them will help your air quality and may let your furnace breathe easier. If the ducts look clean, cleaning them just because time has passed does not do much.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris, then pulls it out through the vacuum. Every vent in the house gets opened and cleaned this way, along with the main trunk lines. The furnace or air handler itself, including the blower and coil, usually gets cleaned as part of the job too, since that's where a lot of the dust collects.
