Eight months of heating pushes a lot of air through your ducts
Your furnace runs October through May here, eight months out of the year, and on nights that average 13°F it runs long and hard to keep up. That is a lot of air moving through the same ductwork, month after month, carrying dust and whatever else is in the house along with it.
Vermillion has also seen 32 winter storms and 40 damaging wind events over the past ten years. Wind like that finds its way into a house, through gaps around vents and returns, and brings dust and debris into the ducts with it. Over time that buildup settles in the trunk lines and branches, and the furnace has to push harder to move the same air through a dirtier duct.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. If nobody in the house has allergies and you haven't had a water leak, a rodent problem, or a renovation that kicked up dust near the ductwork, you don't need to think about it often. A contractor can look at the ducts and tell you whether there's buildup worth removing.
- Is air duct cleaning worth it?
- It's worth it if you can see dust coming out of the vents or you know there's something in the ducts, like debris from a remodel or signs of pests. It won't lower your heating bills or fix a furnace that's struggling, so don't go into it expecting that. What it does is take dust and debris out of the air your furnace is pushing through the house, and that matters here since the furnace runs from October through May.
- What does air duct cleaning involve?
- A contractor puts the duct system under negative pressure with a vacuum unit, then agitates the inside of the ducts with brushes or air tools so the loosened dust and debris get pulled out rather than blown further into the house. Every supply and return vent gets cleaned, along with the main trunk lines. A thorough job also covers the blower compartment and the coil, since dust builds up there too and feeds right back into the ducts if it's left alone.
