Eight months of heating pushes air through your ducts
Your furnace runs October through May here. On the nights that average 17°F, it cycles on and off for hours at a stretch, and every cycle pushes more air through the same ductwork. Dust and whatever else has settled in there over a long heating season rides along with it, back into the rooms you're heating.
Hall County has had 22 winter storms and 117 damaging wind events over the past ten years. A quarter of Nebraska households went at least a day without power in 2024. When a furnace sits idle in a cold house and then kicks back on, it stirs up what settled in the ducts while the air was still.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, but a contractor can tell you by looking at what's actually inside. Homes with pets, a smoker, or someone with allergies tend to need it sooner. If a duct run was opened up during repair work, or you see dust blowing out of the vents when the furnace kicks on, that's a sign to move up the timeline. Going by what's actually in the ducts beats going by the calendar.
- Is air duct cleaning worth it?
- It depends on what's going on in your ducts right now. If there's visible dust buildup, a musty smell when the furnace or AC runs, or you know rodents or debris got into the system, cleaning is worth doing. If none of that applies, a routine cleaning on a system that's otherwise clean won't make a noticeable difference. The filter is what actually cleans the air as it moves through, so a dirty filter is worth checking before anything else.
- What does air duct cleaning involve?
- A technician connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris from the inside of the duct walls, then pulls it out through the vacuum. Every supply and return vent in the house gets opened and cleaned this way. The furnace or air handler itself, along with the coil, usually gets checked and cleaned too since air passes through it on the way to the ducts. A contractor can walk you through what your particular system needs before starting.
