Ten months of heating pushes a lot of air through your ducts
Your furnace runs September through June here, so the blower is moving air through your ductwork almost all year. Every pass carries dust and whatever else is in the house, and most of it settles inside the duct runs rather than making it back to the filter.
Bannock County has seen 79 winter storms and 46 damaging wind events over the past ten years. Storms like that knock out power, and outages mean the system sits idle, then kicks back on and stirs up what's settled since the last run. With winter nights averaging 18°F, that furnace is working hard through the cold months, pushing air through ducts that build up more than they would somewhere milder.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home, so a contractor looks at the ducts before setting a number. Homes here run the furnace September through June, nearly ten months of the year, so ducts move more air and collect more dust than in places with a short heating season. Pets, allergies, or a recent remodel are all reasons to have them checked sooner rather than later.
- Is air duct cleaning worth it?
- It is worth it when there is a reason for it, not on a fixed schedule for its own sake. Visible dust coming out of the vents, a musty smell when the furnace kicks on, or someone in the house with worsening allergies are all reasons to have it done. If none of that is happening, cleaning ducts on a whim will not make the air noticeably better or the furnace run more efficiently.
- What does air duct cleaning involve?
- A contractor connects a powerful vacuum to the duct system, then agitates the inside of each duct with brushes or air tools to knock loose dust and debris so the vacuum can pull it out. This covers the supply and return ducts, the grilles and registers, and usually the blower compartment of the furnace itself. The coil and the filter are separate parts and are not part of a duct cleaning, though a contractor may point out if either needs attention while they are in there.
