Eight months of heat means eight months of dust moving through your ducts
Your furnace runs October through May here, close to eight months of the year. Every time it kicks on, air pushes through the ductwork, and whatever is sitting in there, dust, pet hair, the fine grit that works into a house over a winter, moves with it. With nights averaging 16°F through the coldest stretch, that furnace is cycling on and off all night, every night.
Dodge County has had 17 winter storms and 49 damaging wind events over the past ten years. Storms like that drive dust and debris into a house around doors and windows, and it ends up pulled into the return air and settled in the ducts. A quarter of Nebraska households lost power for a full day or more in 2024, and when a furnace sits off during a cold snap, moisture has a chance to settle in the ductwork before things warm back up and start moving again.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. If anyone in the house has allergies, if you have pets, or if you have had renovation work done that left dust behind, cleaning sooner makes sense. If the vents look clean and nobody is having breathing trouble, you can wait.
- Is air duct cleaning worth it?
- It depends on what is going on in the house. If dust keeps settling back within days of cleaning, or you can see buildup at the vents, clearing the ducts will help. If nobody in the house has breathing trouble and the vents look clean, it is not something you need on a schedule.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system and uses brushes or air tools to knock loose dust and debris from inside the ducts, then pulls it out through the vacuum. Registers and grilles get cleaned too, and both the return and supply sides get covered. The furnace or air handler often gets a look as well, since it connects to the same ductwork.
